# Fallback Providers
feat(auth): same-provider credential pools with rotation, custom endpoint support, and interactive CLI (#2647)
* feat(auth): add same-provider credential pools and rotation UX
Add same-provider credential pooling so Hermes can rotate across
multiple credentials for a single provider, recover from exhausted
credentials without jumping providers immediately, and configure
that behavior directly in hermes setup.
- agent/credential_pool.py: persisted per-provider credential pools
- hermes auth add/list/remove/reset CLI commands
- 429/402/401 recovery with pool rotation in run_agent.py
- Setup wizard integration for pool strategy configuration
- Auto-seeding from env vars and existing OAuth state

* fix(tests): prevent pool auto-seeding from host env in credential pool tests
Tests for non-pool Anthropic paths and auth remove were failing when
host env vars (ANTHROPIC_API_KEY) or file-backed OAuth credentials
were present. The pool auto-seeding picked these up, causing unexpected
pool entries in tests.
- Mock _select_pool_entry in auxiliary_client OAuth flag tests
- Clear Anthropic env vars and mock _seed_from_singletons in auth remove test
* feat(auth): add thread safety, least_used strategy, and request counting
- Add threading.Lock to CredentialPool for gateway thread safety
(concurrent requests from multiple gateway sessions could race on
pool state mutations without this)
- Add 'least_used' rotation strategy that selects the credential
with the lowest request_count, distributing load more evenly
- Add request_count field to PooledCredential for usage tracking
- Add mark_used() method to increment per-credential request counts
- Wrap select(), mark_exhausted_and_rotate(), and try_refresh_current()
with lock acquisition
- Add tests: least_used selection, mark_used counting, concurrent
thread safety (4 threads × 20 selects with no corruption)
* feat(auth): add interactive mode for bare 'hermes auth' command
When 'hermes auth' is called without a subcommand, it now launches an
interactive wizard that:
1. Shows full credential pool status across all providers
2. Offers a menu: add, remove, reset cooldowns, set strategy
3. For OAuth-capable providers (anthropic, nous, openai-codex), the
add flow explicitly asks 'API key or OAuth login?' — making it
clear that both auth types are supported for the same provider
4. Strategy picker shows all 4 options (fill_first, round_robin,
least_used, random) with the current selection marked
5. Remove flow shows entries with indices for easy selection
The subcommand paths (hermes auth add/list/remove/reset) still work
exactly as before for scripted/non-interactive use.
* fix(tests): update runtime_provider tests for config.yaml source of truth (#4165)
Tests were using OPENAI_BASE_URL env var which is no longer consulted
after #4165. Updated to use model config (provider, base_url, api_key)
which is the new single source of truth for custom endpoint URLs.
* feat(auth): support custom endpoint credential pools keyed by provider name
Custom OpenAI-compatible endpoints all share provider='custom', making
the provider-keyed pool useless. Now pools for custom endpoints are
keyed by 'custom:<normalized_name>' where the name comes from the
custom_providers config list (auto-generated from URL hostname).
- Pool key format: 'custom:together.ai', 'custom:local-(localhost:8080)'
- load_pool('custom:name') seeds from custom_providers api_key AND
model.api_key when base_url matches
- hermes auth add/list now shows custom endpoints alongside registry
providers
- _resolve_openrouter_runtime and _resolve_named_custom_runtime check
pool before falling back to single config key
- 6 new tests covering custom pool keying, seeding, and listing
* docs: add Excalidraw diagram of full credential pool flow
Comprehensive architecture diagram showing:
- Credential sources (env vars, auth.json OAuth, config.yaml, CLI)
- Pool storage and auto-seeding
- Runtime resolution paths (registry, custom, OpenRouter)
- Error recovery (429 retry-then-rotate, 402 immediate, 401 refresh)
- CLI management commands and strategy configuration
Open at: https://excalidraw.com/#json=2Ycqhqpi6f12E_3ITyiwh,c7u9jSt5BwrmiVzHGbm87g
* fix(tests): update setup wizard pool tests for unified select_provider_and_model flow
The setup wizard now delegates to select_provider_and_model() instead
of using its own prompt_choice-based provider picker. Tests needed:
- Mock select_provider_and_model as no-op (provider pre-written to config)
- Call _stub_tts BEFORE custom prompt_choice mock (it overwrites it)
- Pre-write model.provider to config so the pool step is reached
* docs: add comprehensive credential pool documentation
- New page: website/docs/user-guide/features/credential-pools.md
Full guide covering quick start, CLI commands, rotation strategies,
error recovery, custom endpoint pools, auto-discovery, thread safety,
architecture, and storage format.
- Updated fallback-providers.md to reference credential pools as the
first layer of resilience (same-provider rotation before cross-provider)
- Added hermes auth to CLI commands reference with usage examples
- Added credential_pool_strategies to configuration guide
* chore: remove excalidraw diagram from repo (external link only)
* refactor: simplify credential pool code — extract helpers, collapse extras, dedup patterns
- _load_config_safe(): replace 4 identical try/except/import blocks
- _iter_custom_providers(): shared generator for custom provider iteration
- PooledCredential.extra dict: collapse 11 round-trip-only fields
(token_type, scope, client_id, portal_base_url, obtained_at,
expires_in, agent_key_id, agent_key_expires_in, agent_key_reused,
agent_key_obtained_at, tls) into a single extra dict with
__getattr__ for backward-compatible access
- _available_entries(): shared exhaustion-check between select and peek
- Dedup anthropic OAuth seeding (hermes_pkce + claude_code identical)
- SimpleNamespace replaces class _Args boilerplate in auth_commands
- _try_resolve_from_custom_pool(): shared pool-check in runtime_provider
Net -17 lines. All 383 targeted tests pass.

Credential pools handle same-provider rotation (e.g., multiple OpenRouter keys). This page covers cross-provider fallback. Both are optional and work independently.

## Primary Model Fallback
When your main LLM provider encounters errors — rate limits, server overload, auth failures, connection drops — Hermes can automatically switch to a backup provider:model pair mid-session without losing your conversation.
### Configuration
docs: two-week gap sweep — platforms, CLI, config, TUI, hooks, providers (#17727)
Covers ~60 merged PRs from Apr 15–29 that shipped user-visible behavior
without docs coverage. No functional code changes; docs + static manifest
regeneration only.
Highlights:
Stale / incorrect:
- configuration.md: auxiliary auto-routing line was wrong since #11900;
now correctly states auto routes to the main model, with a note on the
cost trade-off and per-task override pattern.
- integrations/providers.md + configuration.md compression intro:
removed stale 'Gemini Flash via OpenRouter' claim.
- website/static/api/model-catalog.json: rebuilt from hermes_cli/models.py
so the live manifest picks up tencent/hy3-preview (and remains in sync
for future model-catalog PRs).

- New 'hermes fallback' interactive manager.
- New 'hermes update --check', '--backup' flag, and pre-update pairing
snapshot behavior.
- 'hermes gateway start/restart --all' multi-profile flag.
- cron.md: 'hermes tools' as a platform, per-job enabled_toolsets,
wakeAgent gate, context_from chaining.

- xAI Grok STT as a 6th transcription option.
- 'hermes -z' scripted one-shot mode + HERMES_INFERENCE_MODEL.
Build: 'docusaurus build' succeeds. No new broken links/anchors;
pre-existing warnings unchanged.

The easiest path is the interactive manager:
```bash
hermes fallback
```
`hermes fallback` reuses the provider picker from `hermes model` — same provider list, same credential prompts, same validation. Press `a` to add a fallback, `↑` /`↓` to reorder, `d` to remove, `q` to save and exit. Changes persist under `model.fallback_providers` in `config.yaml` .
If you'd rather edit the YAML directly, add a `fallback_model` section to `~/.hermes/config.yaml` :
2026-03-15 06:24:28 -07:00
```yaml
fallback_model:
provider: openrouter
model: anthropic/claude-sonnet-4
```
Both `provider` and `model` are **required ** . If either is missing, the fallback is disabled.

:::note `fallback_model` vs `fallback_providers`
`fallback_model` (singular) is the legacy single-fallback key — Hermes still honors it for back-compat. `fallback_providers` (plural, list) supports multiple fallbacks tried in order; `hermes fallback` writes to this key. When both are set, Hermes merges them with `fallback_providers` taking priority.

feat(providers): add native NVIDIA NIM provider
Adds NVIDIA NIM as a first-class provider: ProviderConfig in
auth.py, HermesOverlay in providers.py, curated models
(Nemotron plus other open source models hosted on
build.nvidia.com), URL mapping in model_metadata.py, aliases
(nim, nvidia-nim, build-nvidia, nemotron), and env var tests.
Docs updated: providers page, quickstart table, fallback
providers table, and README provider list.

| Google Gemini (OAuth) | `google-gemini-cli` | `hermes model` (Google OAuth; optional: `HERMES_GEMINI_PROJECT_ID` ) |
docs: correctness audit — fix wrong values, add missing coverage (#11972)
Comprehensive audit of every reference/messaging/feature doc page against the
live code registries (PROVIDER_REGISTRY, OPTIONAL_ENV_VARS, COMMAND_REGISTRY,
TOOLSETS, tool registry, on-disk skills). Every fix was verified against code
before writing.
### Wrong values fixed (users would paste-and-fail)
- reference/environment-variables.md:
- DASHSCOPE_BASE_URL default was `coding-intl.dashscope.aliyuncs.com/v1` \u2192
actual `dashscope-intl.aliyuncs.com/compatible-mode/v1`.
- MINIMAX_BASE_URL and MINIMAX_CN_BASE_URL defaults were `/v1` \u2192 actual
`/anthropic` (Hermes calls MiniMax via its Anthropic Messages endpoint).
- reference/toolsets-reference.md MCP example used the non-existent nested
`mcp: servers:` key \u2192 real key is the flat `mcp_servers:`.
- reference/skills-catalog.md listed ~20 bundled skills that no longer exist
on disk (all moved to `optional-skills/`). Regenerated the whole bundled
section from `skills/**/SKILL.md` \u2014 79 skills, accurate paths and names.
- messaging/slack.md ":::info" callout claimed Slack has no
`free_response_channels` equivalent; both the env var and the yaml key are
in fact read.
- messaging/qqbot.md documented `QQ_MARKDOWN_SUPPORT` as an env var, but the
adapter only reads `extra.markdown_support` from config.yaml. Removed the
env var row and noted config-only nature.
- messaging/qqbot.md `hermes setup gateway` \u2192 `hermes gateway setup`.
### Missing coverage added
- Providers: AWS Bedrock and Qwen Portal (qwen-oauth) \u2014 both in
PROVIDER_REGISTRY but undocumented everywhere. Added sections to
integrations/providers.md, rows to quickstart.md and fallback-providers.md.
- integrations/providers.md "Fallback Model" provider list now includes
gemini, google-gemini-cli, qwen-oauth, xai, nvidia, ollama-cloud, bedrock.
- reference/cli-commands.md `--provider` enum and HERMES_INFERENCE_PROVIDER
enum in env-vars now include the same set.
- reference/slash-commands.md: added `/agents` (alias `/tasks`) and `/copy`.
Removed duplicate rows for `/snapshot`, `/fast` (\u00d72), `/debug`.
- reference/tools-reference.md: fixed "47 built-in tools" \u2192 52. Added
`feishu_doc` and `feishu_drive` toolset sections.
- reference/toolsets-reference.md: added `feishu_doc` / `feishu_drive` core
rows + all missing `hermes-<platform>` toolsets in the platform table
(bluebubbles, dingtalk, feishu, qqbot, wecom, wecom-callback, weixin,
homeassistant, webhook, gateway). Fixed the `debugging` composite to
describe the actual `includes=[...]` mechanism.
- reference/optional-skills-catalog.md: added `fitness-nutrition`.
- reference/environment-variables.md: added NOUS_BASE_URL,
NOUS_INFERENCE_BASE_URL, NVIDIA_API_KEY/BASE_URL, OLLAMA_API_KEY/BASE_URL,
XAI_API_KEY/BASE_URL, MISTRAL_API_KEY, AWS_REGION/AWS_PROFILE,
BEDROCK_BASE_URL, HERMES_QWEN_BASE_URL, DISCORD_ALLOWED_CHANNELS,
DISCORD_PROXY, TELEGRAM_REPLY_TO_MODE, MATRIX_DEVICE_ID, MATRIX_REACTIONS,
QQBOT_HOME_CHANNEL_NAME, QQ_SANDBOX.
- messaging/discord.md: documented DISCORD_ALLOWED_CHANNELS, DISCORD_PROXY,
HERMES_DISCORD_TEXT_BATCH_DELAY_SECONDS and HERMES_DISCORD_TEXT_BATCH_SPLIT
_DELAY_SECONDS (all actively read by the adapter).
- messaging/matrix.md: documented MATRIX_REACTIONS (default true).
- messaging/telegram.md: removed the redundant second Webhook Mode section
that invented a `telegram.webhook_mode: true` yaml key the adapter does
not read.
- user-guide/features/hooks.md: added `on_session_finalize` and
`on_session_reset` (both emitted via invoke_hook but undocumented).
- user-guide/features/api-server.md: documented GET /health/detailed, the
`/api/jobs/*` CRUD surface, POST /v1/runs, and GET /v1/runs/{id}/events
(10 routes that were live but undocumented).
- user-guide/features/fallback-providers.md: added `approval` and
`title_generation` auxiliary-task rows; added gemini, bedrock, qwen-oauth
to the supported-providers table.
- user-guide/features/tts.md: "seven providers" \u2192 "eight" (post-xAI add
oversight in #11942).
- user-guide/configuration.md: TTS provider enum gains `xai` and `gemini`;
yaml example block gains `mistral:`, `gemini:`, `xai:` subsections.
Auxiliary-provider enum now enumerates all real registry entries.
- reference/faq.md: stale AIAgent/config examples bumped from
`nous/hermes-3-llama-3.1-70b` and `claude-sonnet-4.6` to
`claude-opus-4.7`.
### Docs-site integrity
- guides/build-a-hermes-plugin.md referenced two nonexistent hooks
(`pre_api_request`, `post_api_request`). Replaced with the real
`on_session_finalize` / `on_session_reset` entries.
- messaging/open-webui.md and features/api-server.md had pre-existing
broken links to `/docs/user-guide/features/profiles` (actual path is
`/docs/user-guide/profiles`). Fixed.
- reference/skills-catalog.md had one `<1%` literal that MDX parsed as a
JSX tag. Escaped to `<1%`.
### False positives filtered out (not changed, verified correct)
- `/set-home` is a registered alias of `/sethome` \u2014 docs were fine.
- `hermes setup gateway` is valid syntax (`hermes setup \<section\>`);
changed in qqbot.md for cross-doc consistency, not as a bug fix.
- Telegram reactions "disabled by default" matches code (default `"false"`).
- Matrix encryption "opt-in" matches code (empty env default \u2192 disabled).
- `pre_api_request` / `post_api_request` hooks do NOT exist in current code;
documented instead the real `on_session_finalize` / `on_session_reset`.
- SIGNAL_IGNORE_STORIES is already in env-vars.md (subagent missed it).
Validation:
- `docusaurus build` \u2014 passes (only pre-existing nix-setup anchor warning).
- `ascii-guard lint docs` \u2014 124 files, 0 errors.
- 22 files changed, +317 / \u2212158.

feat(providers): add Arcee AI as direct API provider
Adds Arcee AI as a standard direct provider (ARCEEAI_API_KEY) with
Trinity models: trinity-large-thinking, trinity-large-preview, trinity-mini.
Standard OpenAI-compatible provider checklist: auth.py, config.py,
models.py, main.py, providers.py, doctor.py, model_normalize.py,
model_metadata.py, setup.py, trajectory_compressor.py.
Based on PR #9274 by arthurbr11, simplified to a standard direct
provider without dual-endpoint OpenRouter routing.

Add GMI Cloud (api.gmi-serving.com) as a full first-class API-key provider
with built-in auth, aliases, model catalog, CLI entry points, auxiliary client
routing, context length resolution, doctor checks, env var tracking, and docs.
- auth.py: ProviderConfig for 'gmi' (api_key, GMI_API_KEY / GMI_BASE_URL)
- providers.py: HermesOverlay with extra_env_vars for models.dev detection
- models.py: curated slash-form model catalog; live /v1/models fetch
- main.py: 'gmi' in _named_custom_provider_map and --provider choices
- model_metadata.py: _URL_TO_PROVIDER, _PROVIDER_PREFIXES, dedicated
context-length probe block (GMI's /models has authoritative data)
- auxiliary_client.py: alias entries; _compat_model fix for slash-form
models on cached aggregator-style clients; gmi aux default model
- doctor.py: GMI in provider connectivity checks
- config.py: GMI_API_KEY / GMI_BASE_URL in OPTIONAL_ENV_VARS
- conftest.py: explicit GMI_BASE_URL clearing (not caught by _API_KEY suffix)
- docs: providers.md, environment-variables.md, fallback-providers.md,
configuration.md, quickstart.md (expands provider table)

docs: resync reference, user-guide, developer-guide, and messaging pages against code (#17738)
Broad drift audit against origin/main (b52b63396).
Reference pages (most user-visible drift):
- slash-commands: add /busy, /curator, /footer, /indicator, /redraw, /steer
that were missing; drop non-existent /terminal-setup; fix /q footnote
(resolves to /queue, not /quit); extend CLI-only list with all 24
CLI-only commands in the registry
- cli-commands: add dedicated sections for hermes curator / fallback /
hooks (new subcommands not previously documented); remove stale
hermes honcho standalone section (the plugin registers dynamically
via hermes memory); list curator/fallback/hooks in top-level table;
fix completion to include fish
- toolsets-reference: document the real 52-toolset count; split browser
vs browser-cdp; add discord / discord_admin / spotify / yuanbao;
correct hermes-cli tool count from 36 to 38; fix misleading claim
that hermes-homeassistant adds tools (it's identical to hermes-cli)
- tools-reference: bump tool count 55 -> 68; add 7 Spotify, 5 Yuanbao,
2 Discord toolsets; move browser_cdp/browser_dialog to their own
browser-cdp toolset section
- environment-variables: add 40+ user-facing HERMES_* vars that were
undocumented (--yolo, --accept-hooks, --ignore-*, inference model
override, agent/stream/checkpoint timeouts, OAuth trace, per-platform
batch tuning for Telegram/Discord/Matrix/Feishu/WeCom, cron knobs,
gateway restart/connect timeouts); dedupe the Cron Scheduler section;
replace stale QQ_SANDBOX with QQ_PORTAL_HOST
User-guide (top level):
- cli.md: compression preserves last 20 turns, not 4 (protect_last_n: 20)
- configuration.md: display.platforms is the canonical per-platform
override key; tool_progress_overrides is deprecated and auto-migrated
- profiles.md: model.default is the config key, not model.model
- sessions.md: CLI/TUI session IDs use 6-char hex, gateway uses 8
- checkpoints-and-rollback.md: destructive-command list now matches
_DESTRUCTIVE_PATTERNS (adds rmdir, cp, install, dd)
- docker.md: the container runs as non-root hermes (UID 10000) via
gosu; fix install command (uv pip); add missing --insecure on the
dashboard compose example (required for non-loopback bind)
- security.md: systemctl danger pattern also matches 'restart'
- index.md: built-in tool count 47 -> 68
- integrations/index.md: 6 STT providers, 8 memory providers
- integrations/providers.md: drop fictional dashscope/qwen aliases
Features:
- overview.md: 9 image models (not 8), 9 TTS providers (not 5),
8 memory providers (Supermemory was missing)
- tool-gateway.md: 9 image models
- tools.md: extend common-toolsets list with search / messaging /
spotify / discord / debugging / safe
- fallback-providers.md: add 6 real providers from PROVIDER_REGISTRY
(lmstudio, kimi-coding-cn, stepfun, alibaba-coding-plan,
tencent-tokenhub, azure-foundry)
- plugins.md: Available Hooks table now includes on_session_finalize,
on_session_reset, subagent_stop
- built-in-plugins.md: add the 7 bundled plugins the page didn't
mention (spotify, google_meet, three image_gen providers, two
dashboard examples)
- web-dashboard.md: add --insecure and --tui flags
- cron.md: hermes cron create takes positional schedule/prompt, not
flags
Messaging:
- telegram.md: TELEGRAM_WEBHOOK_SECRET is now REQUIRED when
TELEGRAM_WEBHOOK_URL is set (gateway refuses to start without it
per GHSA-3vpc-7q5r-276h). Biggest user-visible drift in the batch.
- discord.md: HERMES_DISCORD_TEXT_BATCH_SPLIT_DELAY_SECONDS default
is 2.0, not 0.1
- dingtalk.md: document DINGTALK_REQUIRE_MENTION /
FREE_RESPONSE_CHATS / MENTION_PATTERNS / HOME_CHANNEL /
ALLOW_ALL_USERS that the adapter supports
- bluebubbles.md: drop fictional BLUEBUBBLES_SEND_READ_RECEIPTS env
var; the setting lives in platforms.bluebubbles.extra only
- qqbot.md: drop dead QQ_SANDBOX; add real QQ_PORTAL_HOST and
QQ_GROUP_ALLOWED_USERS
- wecom-callback.md: replace 'hermes gateway start' (service-only)
with 'hermes gateway' for first-time setup
Developer-guide:
- architecture.md: refresh tool/toolset counts (61/52), terminal
backend count (7), line counts for run_agent.py (~13.7k), cli.py
(~11.5k), main.py (~10.4k), setup.py (~3.5k), gateway/run.py
(~12.2k), mcp_tool.py (~3.1k); add yuanbao adapter, bump platform
adapter count 18 -> 20
- agent-loop.md: run_agent.py line count 10.7k -> 13.7k
- tools-runtime.md: add vercel_sandbox backend
- adding-tools.md: remove stale 'Discovery import added to
model_tools.py' checklist item (registry auto-discovery)
- adding-platform-adapters.md: mark send_typing / get_chat_info as
concrete base methods; only connect/disconnect/send are abstract
- acp-internals.md: ACP sessions now persist to SessionDB
(~/.hermes/state.db); acp.run_agent call uses
use_unstable_protocol=True
- cron-internals.md: gateway runs scheduler in a dedicated background
thread via _start_cron_ticker, not on a maintenance cycle; locking
is cross-process via fcntl.flock (Unix) / msvcrt.locking (Windows)
- gateway-internals.md: gateway/run.py ~12k lines
- provider-runtime.md: cron DOES support fallback (run_job reads
fallback_providers from config)
- session-storage.md: SCHEMA_VERSION = 11 (not 9); add migrations
10 and 11 (trigram FTS, inline-mode FTS5 re-index); add
api_call_count column to Sessions DDL; document messages_fts_trigram
and state_meta in the architecture tree
- context-compression-and-caching.md: remove the obsolete 'context
pressure warnings' section (warnings were removed for causing
models to give up early)
- context-engine-plugin.md: compress() signature now includes
focus_topic param
- extending-the-cli.md: _build_tui_layout_children signature now
includes model_picker_widget; add to default layout
Also fixed three pre-existing broken links/anchors the build warned
about (docker.md -> api-server.md, yuanbao.md -> cron-jobs.md and
tips#background-tasks, nix-setup.md -> #container-aware-cli).
Regenerated per-skill pages via website/scripts/generate-skill-docs.py
so catalog tables and sidebar are consistent with current SKILL.md
frontmatter.

feat: add Hugging Face as a first-class inference provider (#3419)
Salvage of PR #1747 (original PR #1171 by @davanstrien) onto current main.
Registers Hugging Face Inference Providers (router.huggingface.co/v1) as a named provider:
- hermes chat --provider huggingface (or --provider hf)
- 18 curated open models via hermes model picker
- HF_TOKEN in ~/.hermes/.env
- OpenAI-compatible endpoint with automatic failover (Groq, Together, SambaNova, etc.)
Files: auth.py, models.py, main.py, setup.py, config.py, model_metadata.py, .env.example, 5 docs pages, 17 new tests.

| Hugging Face | `huggingface` | `HF_TOKEN` |

| Custom endpoint | `custom` | `base_url` + `key_env` (see below) |
2026-03-15 06:24:28 -07:00
### Custom Endpoint Fallback
2026-04-18 15:54:05 -06:00
For a custom OpenAI-compatible endpoint, add `base_url` and optionally `key_env` :
2026-03-15 06:24:28 -07:00
```yaml
fallback_model:
provider: custom
model: my-local-model
base_url: http://localhost:8000/v1
2026-04-18 15:54:05 -06:00
key_env: MY_LOCAL_KEY # env var name containing the API key
2026-03-15 06:24:28 -07:00
```
### When Fallback Triggers
The fallback activates automatically when the primary model fails with:
- **Rate limits** (HTTP 429) — after exhausting retry attempts
- **Server errors** (HTTP 500, 502, 503) — after exhausting retry attempts
- **Auth failures** (HTTP 401, 403) — immediately (no point retrying)
- **Not found** (HTTP 404) — immediately
- **Invalid responses** — when the API returns malformed or empty responses repeatedly
When triggered, Hermes:
1. Resolves credentials for the fallback provider
2. Builds a new API client
3. Swaps the model, provider, and client in-place
4. Resets the retry counter and continues the conversation
The switch is seamless — your conversation history, tool calls, and context are preserved. The agent continues from exactly where it left off, just using a different model.
2026-04-20 17:18:53 +08:00
:::info Per-Turn, Not Per-Session
Fallback is **turn-scoped ** : each new user message starts with the primary model restored. If the primary fails mid-turn, fallback activates for that turn only. On the next message, Hermes tries the primary again. Within a single turn, fallback activates at most once — if the fallback also fails, normal error handling takes over (retries, then error message). This prevents cascading failover loops within a turn while giving the primary model a fresh chance every turn.

### Examples
**OpenRouter as fallback for Anthropic native:**
```yaml
model:
provider: anthropic
default: claude-sonnet-4-6
fallback_model:
provider: openrouter
model: anthropic/claude-sonnet-4
```
**Nous Portal as fallback for OpenRouter:**
```yaml
model:
provider: openrouter
default: anthropic/claude-opus-4
fallback_model:
provider: nous
model: nous-hermes-3
```
**Local model as fallback for cloud:**
```yaml
fallback_model:
provider: custom
model: llama-3.1-70b
base_url: http://localhost:8000/v1
2026-04-18 15:54:05 -06:00
key_env: LOCAL_API_KEY
2026-03-15 06:24:28 -07:00
```
**Codex OAuth as fallback:**
```yaml
fallback_model:
provider: openai-codex
model: gpt-5.3-codex
```
### Where Fallback Works
| Context | Fallback Supported |
|---------|-------------------|
| CLI sessions | ✔ |
| Messaging gateway (Telegram, Discord, etc.) | ✔ |
| Subagent delegation | ✘ (subagents do not inherit fallback config) |
| Cron jobs | ✘ (run with a fixed provider) |
| Auxiliary tasks (vision, compression) | ✘ (use their own provider chain — see below) |
:::tip
There are no environment variables for `fallback_model` — it is configured exclusively through `config.yaml` . This is intentional: fallback configuration is a deliberate choice, not something a stale shell export should override.
:::
---
## Auxiliary Task Fallback
Hermes uses separate lightweight models for side tasks. Each task has its own provider resolution chain that acts as a built-in fallback system.
### Tasks with Independent Provider Resolution
| Task | What It Does | Config Key |
|------|-------------|-----------|
| Vision | Image analysis, browser screenshots | `auxiliary.vision` |
| Web Extract | Web page summarization | `auxiliary.web_extract` |

docs: correctness audit — fix wrong values, add missing coverage (#11972)
Comprehensive audit of every reference/messaging/feature doc page against the
live code registries (PROVIDER_REGISTRY, OPTIONAL_ENV_VARS, COMMAND_REGISTRY,
TOOLSETS, tool registry, on-disk skills). Every fix was verified against code
before writing.
### Wrong values fixed (users would paste-and-fail)
- reference/environment-variables.md:
- DASHSCOPE_BASE_URL default was `coding-intl.dashscope.aliyuncs.com/v1` \u2192
actual `dashscope-intl.aliyuncs.com/compatible-mode/v1`.
- MINIMAX_BASE_URL and MINIMAX_CN_BASE_URL defaults were `/v1` \u2192 actual
`/anthropic` (Hermes calls MiniMax via its Anthropic Messages endpoint).
- reference/toolsets-reference.md MCP example used the non-existent nested
`mcp: servers:` key \u2192 real key is the flat `mcp_servers:`.
- reference/skills-catalog.md listed ~20 bundled skills that no longer exist
on disk (all moved to `optional-skills/`). Regenerated the whole bundled
section from `skills/**/SKILL.md` \u2014 79 skills, accurate paths and names.
- messaging/slack.md ":::info" callout claimed Slack has no
`free_response_channels` equivalent; both the env var and the yaml key are
in fact read.
- messaging/qqbot.md documented `QQ_MARKDOWN_SUPPORT` as an env var, but the
adapter only reads `extra.markdown_support` from config.yaml. Removed the
env var row and noted config-only nature.
- messaging/qqbot.md `hermes setup gateway` \u2192 `hermes gateway setup`.
### Missing coverage added
- Providers: AWS Bedrock and Qwen Portal (qwen-oauth) \u2014 both in
PROVIDER_REGISTRY but undocumented everywhere. Added sections to
integrations/providers.md, rows to quickstart.md and fallback-providers.md.
- integrations/providers.md "Fallback Model" provider list now includes
gemini, google-gemini-cli, qwen-oauth, xai, nvidia, ollama-cloud, bedrock.
- reference/cli-commands.md `--provider` enum and HERMES_INFERENCE_PROVIDER
enum in env-vars now include the same set.
- reference/slash-commands.md: added `/agents` (alias `/tasks`) and `/copy`.
Removed duplicate rows for `/snapshot`, `/fast` (\u00d72), `/debug`.
- reference/tools-reference.md: fixed "47 built-in tools" \u2192 52. Added
`feishu_doc` and `feishu_drive` toolset sections.
- reference/toolsets-reference.md: added `feishu_doc` / `feishu_drive` core
rows + all missing `hermes-<platform>` toolsets in the platform table
(bluebubbles, dingtalk, feishu, qqbot, wecom, wecom-callback, weixin,
homeassistant, webhook, gateway). Fixed the `debugging` composite to
describe the actual `includes=[...]` mechanism.
- reference/optional-skills-catalog.md: added `fitness-nutrition`.
- reference/environment-variables.md: added NOUS_BASE_URL,
NOUS_INFERENCE_BASE_URL, NVIDIA_API_KEY/BASE_URL, OLLAMA_API_KEY/BASE_URL,
XAI_API_KEY/BASE_URL, MISTRAL_API_KEY, AWS_REGION/AWS_PROFILE,
BEDROCK_BASE_URL, HERMES_QWEN_BASE_URL, DISCORD_ALLOWED_CHANNELS,
DISCORD_PROXY, TELEGRAM_REPLY_TO_MODE, MATRIX_DEVICE_ID, MATRIX_REACTIONS,
QQBOT_HOME_CHANNEL_NAME, QQ_SANDBOX.
- messaging/discord.md: documented DISCORD_ALLOWED_CHANNELS, DISCORD_PROXY,
HERMES_DISCORD_TEXT_BATCH_DELAY_SECONDS and HERMES_DISCORD_TEXT_BATCH_SPLIT
_DELAY_SECONDS (all actively read by the adapter).
- messaging/matrix.md: documented MATRIX_REACTIONS (default true).
- messaging/telegram.md: removed the redundant second Webhook Mode section
that invented a `telegram.webhook_mode: true` yaml key the adapter does
not read.
- user-guide/features/hooks.md: added `on_session_finalize` and
`on_session_reset` (both emitted via invoke_hook but undocumented).
- user-guide/features/api-server.md: documented GET /health/detailed, the
`/api/jobs/*` CRUD surface, POST /v1/runs, and GET /v1/runs/{id}/events
(10 routes that were live but undocumented).
- user-guide/features/fallback-providers.md: added `approval` and
`title_generation` auxiliary-task rows; added gemini, bedrock, qwen-oauth
to the supported-providers table.
- user-guide/features/tts.md: "seven providers" \u2192 "eight" (post-xAI add
oversight in #11942).
- user-guide/configuration.md: TTS provider enum gains `xai` and `gemini`;
yaml example block gains `mistral:`, `gemini:`, `xai:` subsections.
Auxiliary-provider enum now enumerates all real registry entries.
- reference/faq.md: stale AIAgent/config examples bumped from
`nous/hermes-3-llama-3.1-70b` and `claude-sonnet-4.6` to
`claude-opus-4.7`.
### Docs-site integrity
- guides/build-a-hermes-plugin.md referenced two nonexistent hooks
(`pre_api_request`, `post_api_request`). Replaced with the real
`on_session_finalize` / `on_session_reset` entries.
- messaging/open-webui.md and features/api-server.md had pre-existing
broken links to `/docs/user-guide/features/profiles` (actual path is
`/docs/user-guide/profiles`). Fixed.
- reference/skills-catalog.md had one `<1%` literal that MDX parsed as a
JSX tag. Escaped to `<1%`.
### False positives filtered out (not changed, verified correct)
- `/set-home` is a registered alias of `/sethome` \u2014 docs were fine.
- `hermes setup gateway` is valid syntax (`hermes setup \<section\>`);
changed in qqbot.md for cross-doc consistency, not as a bug fix.
- Telegram reactions "disabled by default" matches code (default `"false"`).
- Matrix encryption "opt-in" matches code (empty env default \u2192 disabled).
- `pre_api_request` / `post_api_request` hooks do NOT exist in current code;
documented instead the real `on_session_finalize` / `on_session_reset`.
- SIGNAL_IGNORE_STORIES is already in env-vars.md (subagent missed it).
Validation:
- `docusaurus build` \u2014 passes (only pre-existing nix-setup anchor warning).
- `ascii-guard lint docs` \u2014 124 files, 0 errors.
- 22 files changed, +317 / \u2212158.

### Auto-Detection Chain
When a task's provider is set to `"auto"` (the default), Hermes tries providers in order until one works:
**For text tasks (compression, web extract, etc.):**
```text
OpenRouter → Nous Portal → Custom endpoint → Codex OAuth →
2026-04-11 11:02:58 -07:00
API-key providers (z.ai, Kimi, MiniMax, Xiaomi MiMo, Hugging Face, Anthropic) → give up
2026-03-15 06:24:28 -07:00
```
**For vision tasks:**
```text
Main provider (if vision-capable) → OpenRouter → Nous Portal →
Codex OAuth → Anthropic → Custom endpoint → give up
```
If the resolved provider fails at call time, Hermes also has an internal retry: if the provider is not OpenRouter and no explicit `base_url` is set, it tries OpenRouter as a last-resort fallback.
### Configuring Auxiliary Providers
Each task can be configured independently in `config.yaml` :
```yaml
auxiliary:
vision:
provider: "auto" # auto | openrouter | nous | codex | main | anthropic
model: "" # e.g. "openai/gpt-4o"
base_url: "" # direct endpoint (takes precedence over provider)
api_key: "" # API key for base_url
web_extract:
provider: "auto"
model: ""
compression:
provider: "auto"
model: ""
session_search:
provider: "auto"
model: ""
2026-04-19 13:11:22 -06:00
timeout: 30
max_concurrency: 3
extra_body: {}
2026-03-15 06:24:28 -07:00
skills_hub:
provider: "auto"
model: ""
mcp:
provider: "auto"
model: ""
```

auxiliary:
compression:
provider: main # Same provider options as other auxiliary tasks
model: google/gemini-3-flash-preview
base_url: null # Custom OpenAI-compatible endpoint
2026-03-17 04:46:15 -07:00
```
And the fallback model uses:
```yaml
fallback_model:
provider: openrouter
model: anthropic/claude-sonnet-4
# base_url: http://localhost:8000/v1 # Optional custom endpoint
2026-03-15 06:24:28 -07:00
```
2026-04-19 13:11:22 -06:00
For `auxiliary.session_search` , Hermes also supports:
- `max_concurrency` to limit how many session summaries run at once
- `extra_body` to pass provider-specific OpenAI-compatible request fields through on the summarization calls
Example:
```yaml
auxiliary:
session_search:
provider: main
model: glm-4.5-air
max_concurrency: 2
extra_body:
enable_thinking: false
```
If your provider does not support a native OpenAI-compatible reasoning-control field, `extra_body` will not help for that part; in that case `max_concurrency` is still useful for reducing request-burst 429s.
2026-03-17 04:46:15 -07:00
All three — auxiliary, compression, fallback — work the same way: set `provider` to pick who handles the request, `model` to pick which model, and `base_url` to point at a custom endpoint (overrides provider).
2026-03-15 06:24:28 -07:00
### Provider Options for Auxiliary Tasks
2026-04-08 16:39:17 -07:00
These options apply to `auxiliary:` , `compression:` , and `fallback_model:` configs only — `"main"` is **not ** a valid value for your top-level `model.provider` . For custom endpoints, use `provider: custom` in your `model:` section (see [AI Providers ](/docs/integrations/providers )).
2026-03-15 06:24:28 -07:00
| Provider | Description | Requirements |
|----------|-------------|-------------|
| `"auto"` | Try providers in order until one works (default) | At least one provider configured |
| `"openrouter"` | Force OpenRouter | `OPENROUTER_API_KEY` |
2026-04-06 17:17:57 -07:00
| `"nous"` | Force Nous Portal | `hermes auth` |
2026-03-15 06:24:28 -07:00
| `"codex"` | Force Codex OAuth | `hermes model` → Codex |
2026-04-08 16:39:17 -07:00
| `"main"` | Use whatever provider the main agent uses (auxiliary tasks only) | Active main provider configured |
2026-03-15 06:24:28 -07:00
| `"anthropic"` | Force Anthropic native | `ANTHROPIC_API_KEY` or Claude Code credentials |
### Direct Endpoint Override
For any auxiliary task, setting `base_url` bypasses provider resolution entirely and sends requests directly to that endpoint:
```yaml
auxiliary:
vision:
base_url: "http://localhost:1234/v1"
api_key: "local-key"
model: "qwen2.5-vl"
```
`base_url` takes precedence over `provider` . Hermes uses the configured `api_key` for authentication, falling back to `OPENAI_API_KEY` if not set. It does **not ** reuse `OPENROUTER_API_KEY` for custom endpoints.

Older configs with `compression.summary_model` / `compression.summary_provider` / `compression.summary_base_url` are automatically migrated to `auxiliary.compression.*` on first load (config version 17).

If no provider is available for compression, Hermes drops middle conversation turns without generating a summary rather than failing the session.

## Delegation Provider Override
Subagents spawned by `delegate_task` do **not ** use the primary fallback model. However, they can be routed to a different provider:model pair for cost optimization:
```yaml
delegation:
provider: "openrouter" # override provider for all subagents
model: "google/gemini-3-flash-preview" # override model
# base_url: "http://localhost:1234/v1" # or use a direct endpoint
# api_key: "local-key"
```
See [Subagent Delegation ](/docs/user-guide/features/delegation ) for full configuration details.
---
## Cron Job Providers
Cron jobs run with whatever provider is configured at execution time. They do not support a fallback model. To use a different provider for cron jobs, configure `provider` and `model` overrides on the cron job itself:
```python
cronjob(
action="create",
schedule="every 2h",
prompt="Check server status",
provider="openrouter",
model="google/gemini-3-flash-preview"
)
```
See [Scheduled Tasks (Cron) ](/docs/user-guide/features/cron ) for full configuration details.

docs: correctness audit — fix wrong values, add missing coverage (#11972)
Comprehensive audit of every reference/messaging/feature doc page against the
live code registries (PROVIDER_REGISTRY, OPTIONAL_ENV_VARS, COMMAND_REGISTRY,
TOOLSETS, tool registry, on-disk skills). Every fix was verified against code
before writing.
### Wrong values fixed (users would paste-and-fail)
- reference/environment-variables.md:
- DASHSCOPE_BASE_URL default was `coding-intl.dashscope.aliyuncs.com/v1` \u2192
actual `dashscope-intl.aliyuncs.com/compatible-mode/v1`.
- MINIMAX_BASE_URL and MINIMAX_CN_BASE_URL defaults were `/v1` \u2192 actual
`/anthropic` (Hermes calls MiniMax via its Anthropic Messages endpoint).
- reference/toolsets-reference.md MCP example used the non-existent nested
`mcp: servers:` key \u2192 real key is the flat `mcp_servers:`.
- reference/skills-catalog.md listed ~20 bundled skills that no longer exist
on disk (all moved to `optional-skills/`). Regenerated the whole bundled
section from `skills/**/SKILL.md` \u2014 79 skills, accurate paths and names.
- messaging/slack.md ":::info" callout claimed Slack has no
`free_response_channels` equivalent; both the env var and the yaml key are
in fact read.
- messaging/qqbot.md documented `QQ_MARKDOWN_SUPPORT` as an env var, but the
adapter only reads `extra.markdown_support` from config.yaml. Removed the
env var row and noted config-only nature.
- messaging/qqbot.md `hermes setup gateway` \u2192 `hermes gateway setup`.
### Missing coverage added
- Providers: AWS Bedrock and Qwen Portal (qwen-oauth) \u2014 both in
PROVIDER_REGISTRY but undocumented everywhere. Added sections to
integrations/providers.md, rows to quickstart.md and fallback-providers.md.
- integrations/providers.md "Fallback Model" provider list now includes
gemini, google-gemini-cli, qwen-oauth, xai, nvidia, ollama-cloud, bedrock.
- reference/cli-commands.md `--provider` enum and HERMES_INFERENCE_PROVIDER
enum in env-vars now include the same set.
- reference/slash-commands.md: added `/agents` (alias `/tasks`) and `/copy`.
Removed duplicate rows for `/snapshot`, `/fast` (\u00d72), `/debug`.
- reference/tools-reference.md: fixed "47 built-in tools" \u2192 52. Added
`feishu_doc` and `feishu_drive` toolset sections.
- reference/toolsets-reference.md: added `feishu_doc` / `feishu_drive` core
rows + all missing `hermes-<platform>` toolsets in the platform table
(bluebubbles, dingtalk, feishu, qqbot, wecom, wecom-callback, weixin,
homeassistant, webhook, gateway). Fixed the `debugging` composite to
describe the actual `includes=[...]` mechanism.
- reference/optional-skills-catalog.md: added `fitness-nutrition`.
- reference/environment-variables.md: added NOUS_BASE_URL,
NOUS_INFERENCE_BASE_URL, NVIDIA_API_KEY/BASE_URL, OLLAMA_API_KEY/BASE_URL,
XAI_API_KEY/BASE_URL, MISTRAL_API_KEY, AWS_REGION/AWS_PROFILE,
BEDROCK_BASE_URL, HERMES_QWEN_BASE_URL, DISCORD_ALLOWED_CHANNELS,
DISCORD_PROXY, TELEGRAM_REPLY_TO_MODE, MATRIX_DEVICE_ID, MATRIX_REACTIONS,
QQBOT_HOME_CHANNEL_NAME, QQ_SANDBOX.
- messaging/discord.md: documented DISCORD_ALLOWED_CHANNELS, DISCORD_PROXY,
HERMES_DISCORD_TEXT_BATCH_DELAY_SECONDS and HERMES_DISCORD_TEXT_BATCH_SPLIT
_DELAY_SECONDS (all actively read by the adapter).
- messaging/matrix.md: documented MATRIX_REACTIONS (default true).
- messaging/telegram.md: removed the redundant second Webhook Mode section
that invented a `telegram.webhook_mode: true` yaml key the adapter does
not read.
- user-guide/features/hooks.md: added `on_session_finalize` and
`on_session_reset` (both emitted via invoke_hook but undocumented).
- user-guide/features/api-server.md: documented GET /health/detailed, the
`/api/jobs/*` CRUD surface, POST /v1/runs, and GET /v1/runs/{id}/events
(10 routes that were live but undocumented).
- user-guide/features/fallback-providers.md: added `approval` and
`title_generation` auxiliary-task rows; added gemini, bedrock, qwen-oauth
to the supported-providers table.
- user-guide/features/tts.md: "seven providers" \u2192 "eight" (post-xAI add
oversight in #11942).
- user-guide/configuration.md: TTS provider enum gains `xai` and `gemini`;
yaml example block gains `mistral:`, `gemini:`, `xai:` subsections.
Auxiliary-provider enum now enumerates all real registry entries.
- reference/faq.md: stale AIAgent/config examples bumped from
`nous/hermes-3-llama-3.1-70b` and `claude-sonnet-4.6` to
`claude-opus-4.7`.
### Docs-site integrity
- guides/build-a-hermes-plugin.md referenced two nonexistent hooks
(`pre_api_request`, `post_api_request`). Replaced with the real
`on_session_finalize` / `on_session_reset` entries.
- messaging/open-webui.md and features/api-server.md had pre-existing
broken links to `/docs/user-guide/features/profiles` (actual path is
`/docs/user-guide/profiles`). Fixed.
- reference/skills-catalog.md had one `<1%` literal that MDX parsed as a
JSX tag. Escaped to `<1%`.
### False positives filtered out (not changed, verified correct)
- `/set-home` is a registered alias of `/sethome` \u2014 docs were fine.
- `hermes setup gateway` is valid syntax (`hermes setup \<section\>`);
changed in qqbot.md for cross-doc consistency, not as a bug fix.
- Telegram reactions "disabled by default" matches code (default `"false"`).
- Matrix encryption "opt-in" matches code (empty env default \u2192 disabled).
- `pre_api_request` / `post_api_request` hooks do NOT exist in current code;
documented instead the real `on_session_finalize` / `on_session_reset`.
- SIGNAL_IGNORE_STORIES is already in env-vars.md (subagent missed it).
Validation:
- `docusaurus build` \u2014 passes (only pre-existing nix-setup anchor warning).
- `ascii-guard lint docs` \u2014 124 files, 0 errors.
- 22 files changed, +317 / \u2212158.
