feat: Litellm OpenAI compatible router - #2263
Conversation
Introduces a LiteLLM-backed model catalog service and wires new OpenAI-compatible `/v1` endpoints (`/models`, `/model-catalog`, `/chat/completions`, `/embeddings`) through a new gateway that resolves provider credentials server-side. The frontend model pickers now consume a single catalog query (with custom model entry support), and Langflow integration is updated to call the OpenRAG proxy via `OPENRAG_LLM_BASE_URL` using caller JWTs instead of forwarding provider API keys; related unit tests and env docs were added.
This change expands OpenRAG beyond the fixed provider list by allowing arbitrary LiteLLM providers to be configured, stored, validated, and used across onboarding, settings, health checks, model listing, and gateway calls. It introduces generic provider credential payloads in API models, custom provider persistence/encryption in config management, provider removal handling with fallbacks, and runtime credential resolution for non-legacy providers. On the frontend, onboarding and settings now use catalog-defined credential fields (including custom providers), add a generic provider configuration dialog, and surface configured custom providers alongside built-ins. Model selection UX is improved with deferred search limits and reusable model capability/details panels in onboarding, agent settings, and ingest settings. Unit tests were updated and expanded to cover arbitrary provider credentials, config round-tripping, gateway credential handling, and flow update behavior for non-legacy providers.
Introduces a provider-logo mapping helper with family-prefix resolution and monogram fallbacks, plus tests to ensure mapped assets exist and fallback initials stay stable. Updates onboarding and settings model/provider pickers to accept per-option icons and render vendor marks consistently, and vendors the logo assets with source attribution for offline-safe rendering.
Model feature panels now show a provider mark (logo when available, monogram fallback) plus a clearer model/provider header in onboarding and settings views. The provider identifier is passed through all ModelFeatures call sites to support this. On onboarding, auto-selection now prefers an OpenAI model when no explicit default is found, giving a more predictable first-time default choice.
Improve model selection and onboarding/settings behavior when the same model ID exists across multiple providers by tracking `selectedProvider` and adding provider-aware selection helpers. Catalog options are now ranked to prioritize real, capability-complete defaults over template/finetune rows. Add credential snapshot helpers so onboarding can reuse saved provider credentials (including legacy OpenAI/Anthropic/Watsonx/Ollama fields) without forcing re-entry, and only submit new credentials when needed. Backend settings payload generation was refactored to preserve legacy secret fields while merging custom provider credentials, with unit tests updated to cover provider disambiguation, ranking, and secret preservation.
Introduces new OpenRAG LLM and Embeddings components (plus component index registration) and switches bundled flows to use them instead of generic model nodes. The update standardizes runtime auth/base-url wiring on `OPENRAG_LLM_TOKEN` and `OPENRAG_LLM_BASE_URL`, seeds non-empty placeholders across Docker/Helm/operator envs, and updates Langflow global-variable sync and header injection accordingly. It also adds scripts/tests for patching Langflow sidebar bundle entries and keeping component metadata in sync.
Ingestion failed for every file during onboarding with: Flow build blocked: custom components are not allowed: OpenSearch (Multi-Model Multi-Embedding) Two independent Langflow 1.11 behaviours caused it. 1. Langflow's extension migration table claims the bare class name OpenSearchVectorStoreComponentMultimodalMultiEmbedding and rewrites every node carrying it to ext:elastic:...@official before validation runs. That bundle is not installed here, so the node's type resolved to nothing and the restricted-mode gate blocked the whole flow. Reference our own copy by its canonical ext:openrag:...@extra id instead, which the rewriter leaves alone, and rename the inline bundle directory to lowercase snake_case so Langflow's extension loader accepts it (it was rejecting 'OpenRAG' with inline-bundle-name-invalid, which is why the ext id had nothing to resolve to). 2. update_openrag_component_index.py computed the index integrity digest with json.dumps' default ensure_ascii=True when orjson is absent. Langflow hashes the orjson/UTF-8 encoding, so the digests never matched, it logged "SHA256 mismatch (file may be corrupted or tampered)" and silently discarded the index -- taking the OpenRAG bundle with it and adding ~8s to every startup. Also refreshes the stale MCPTools code embedded in openrag_agent.json, which would otherwise fail the same gate with "outdated components must be updated before running".
Picking a LiteLLM provider meant opening "Configure provider" and hunting through a dropdown, so the catalogue was invisible until you went looking for it. Render every provider the installed LiteLLM version supports as a box instead, with a search field at the top of the page. Ordering is preserved: the four providers with bespoke dialogs stay first in their existing order, the already-configured custom providers follow, and the rest of the catalogue sits below under "All providers". Clicking any catalogue box opens the generic dialog with that provider preselected.
The health banner showed "<Provider> error - cache_key() got an unexpected keyword argument 'credentials'" on every page. The endpoint passes credentials= to provider_health_cache.cache_key(), but that function never gained the parameter, so the call raised TypeError before any provider was actually contacted. Nothing about it is provider-specific — whichever provider happened to be configured got blamed, and no provider could ever report healthy. Give cache_key() credentials/embedding_credentials and fold them into the digest, hashed like the existing api_key fields so secrets stay out of the key. They belong in it regardless: generic LiteLLM providers keep their secrets there rather than in api_key/endpoint/project_id, so rotating one would otherwise keep serving the pre-rotation verdict for the whole TTL. The endpoint also computed embedding_credentials without passing it, so the embedding side had the same staleness. Separately, the specific-provider branch called validate_provider_setup without credentials, so validating a generic provider from the providers page ran with no credentials at all. Forward them there too.
The new catalogue cards reused getModelLogo, which is built for dropdown rows: an 11px image inside a 16px frame. Dropped into a card tile it looked noticeably smaller than the bespoke provider SVGs beside it, which draw at ~17px. Render the mark directly at 17px and reuse CardIcon for the tile so both grids stay identical, rather than enlarging the tile — that size was already right.
Configuring a provider only wrote the credentials down. Nothing checked them, so a wrong api_base or a deployment name that does not exist on the account surfaced much later as a mid-chat or mid-ingest failure -- "litellm.APIError: AzureException APIError - Resource not found". The generic provider dialog now saves, then issues one real call through LiteLLM and shows the provider's own error inline, keeping the dialog open so the values can be corrected. Making that possible needed a model to test with. Generic providers are validated by an actual completion/embedding call, and the endpoint only had a model when the provider being checked happened to be the selected LLM or embedding provider -- otherwise validation failed with "A model is required to validate the provider". Catalogue model names do not help for Azure, Bedrock or SageMaker either, where names are per-account deployments. So the endpoint takes an explicit model/embedding_model_override, and the dialog asks for one, seeded from the catalogue and falling back to the provider's placeholder. Verified against a deliberately wrong Azure endpoint: the dialog stays open showing the connection error rather than reporting success.

"Update required from Langflow" reappeared more or less constantly. The check compared the flow file's mtime against Langflow's updated_at, and mtime says nothing about content: git checkout, pull, stash/pop, a branch switch, a fresh clone, and any container rebuild that re-COPYs flows/ all restamp every flow file without changing a byte. Each of those made all four flows look newer than Langflow's copies, so the prompt came back and asked the user to overwrite flows with identical content. Keep the mtime test as the cheap pre-filter, then confirm the shipped definition actually differs before reporting an update. The comparison covers the component set, each component's code hash, and the wiring, and ignores node positions and template values -- OpenRAG rewrites values in the Langflow copy every time settings are applied (models, chunk size, credentials), so a whole-payload comparison would report an update forever instead of never. Verified live: touching all four flow files reports nothing, while changing one component's code hash still reports that flow.

Empty api_base silently routes OpenRAG traffic to the public OpenAI endpoint. All four components build their client with base_url = api_base or None. When OPENRAG_LLM_BASE_URL resolves empty — which docker-compose.yml line 179 permits by default — ChatOpenAI and OpenAIEmbeddings fall back to https://api.openai.com/v1 and send the OpenRAG hop token there. The shared root cause is the missing required-value check on api_base.

custom_components/openrag/openai_compatible_llm.py (118-127), build_embeddings

Do not restrict catalog embedding options to four providers.
groupedCatalogOptions already filters by provider key. The isCatalogProvider allow-list adds a second filter that returns [] for every other provider. This PR adds generic LiteLLM provider configuration, so a user can select an embedding provider such as gemini or bedrock. For those providers, the picker silently falls back to the static list and the catalog models never appear.
Remove the allow-list and pass the current provider key directly.

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift
Generic providers always run a paid validation call, ignoring test_completion=False.
For any provider outside {openai, watsonx, ollama, anthropic}, validate_provider_setup always calls _test_litellm_provider, which issues a real litellm.acompletion or litellm.aembedding request. The test_completion flag has no effect on this branch. The function's own docstring states test_completion=False performs lightweight validation with no credits consumed, but that guarantee does not hold for generic providers.
Periodic provider-health polling normally calls with test_completion=False. For a custom provider, every polling cycle that misses the health cache still issues a real, credit-consuming call, unlike known providers, which get a genuinely free check (/v1/models, IAM token, or endpoint status).
Add a lightweight check for generic providers, or skip validation entirely when test_completion is False and the provider is generic, so periodic health polling does not consume credits.

remove_provider_config does not clear legacy fields for a known provider name.
set_credentials keeps a known provider's legacy fields (for example providers.openai.api_key/.configured) synchronized with providers.custom[provider]. remove_provider_config only deletes working_config.providers.custom[provider]. It does not clear the matching legacy fields.
If remove_provider_config is ever called with "openai", "anthropic", "watsonx", or "ollama", the provider stays configured through its legacy fields. any_configured() and _custom_providers_for_settings both still report it as configured, so the removal appears to succeed but leaves stale credentials in place.
Reject remove_provider_config requests for the four known provider names (direct them to remove_<provider>_config instead), or clear the matching legacy fields when the removed name matches one of them.

Forward dimensions, encoding_format, and user to litellm.aembedding.
Only model and input are forwarded. OpenAI-compatible clients commonly send dimensions and encoding_format. Dropping dimensions silently returns a vector of the provider default size instead of the requested size. LangflowFileService._detect_embedding_dimensions builds the OpenSearch mapping from a probe through this same path, so a caller that requests a reduced dimension writes vectors that do not match the mapping. Dropping encoding_format returns floats where the client expects base64.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Do not bypass strict routing for an unconfigured provider.
is_known_provider(prefix) only shows that LiteLLM recognizes the prefix. It does not show that this workspace configured the provider. With strict=True, a value such as groq/model returns here and bypasses the UnknownEmbeddingProvider path at Lines 254-259.
Check configured-provider state before preserving the prefix, or skip this fast path in strict mode. Otherwise an unconfigured prefixed model reaches LiteLLM instead of failing fast as this method documents.
