Description

Replace the flat UnifiedInferenceProvider with a discriminated union of seven typed inference providers and nested connection configs.

Adds structured allowed_models (string shorthand or catalog entry), skip_model_discovery, provider id defaults/validation, and unique id / model-name checks. Drops OGX-era ollama / vllm_rhaiis / vllm_rhel_ai; adds bedrock. Keeps deprecated api_key_env / extra for compatibility. Config-only — synthesizer / OGX runtime unchanged.

Checklist before requesting a review

  • I have performed a self-review of my code.
  • PR has passed all pre-merge test jobs.
  • If it is a core feature, I have added thorough tests.

Testing

  • uv run pytest tests/unit/models/config/test_inference_provider_entries.py tests/unit/models/config/test_inference_configuration.py tests/unit/telemetry/test_configuration_snapshot.py tests/unit/test_ogx_synthesize.py tests/unit/utils/dumpers/test_models_dumper.py::test_dump_models

Verified: unit tests for discriminated providers, AllowedModel coercion, skip-discovery / ST allow-list rules, unique provider ids, and telemetry snapshot masking of nested config.

Summary by CodeRabbit

  • New Features
    • Inference provider configurations now support typed, provider-specific settings for Azure, Bedrock, OpenAI, Sentence Transformers, Vertex AI, vLLM, and WatsonX.
    • Allowed model lists support model types and metadata, alongside provider-specific model discovery options.
  • Improvements
    • Provider IDs and model names are validated for uniqueness. Skipping model discovery requires an allowed-model list, and Sentence Transformers requires configured models.
    • Telemetry snapshots indicate whether provider configuration is set without exposing its contents.
  • Documentation
    • Updated configuration references to describe provider-specific inference settings.

Walkthrough

The change replaces the generic inference provider model with seven typed provider entries. It adds provider-specific configuration and model validation, updates provider schemas and documentation, and masks provider configuration values in telemetry snapshots.

Changes

Typed inference provider configuration

Layer / File(s) Summary
Provider models and validation
src/models/config.py, tests/unit/models/config/*, tests/unit/test_ogx_synthesize.py
Seven typed provider entries replace the generic provider model. Allowed models support string or structured input. Validation covers provider IDs, duplicate model names, and discovery settings.
Provider schemas and references
docs/devel_doc/openapi.json, docs/models/successful_responses.*, docs/user_doc/config.*, tests/unit/utils/dumpers/test_models_dumper.py
The OpenAPI contract adds provider-specific schemas and changes InferenceConfiguration.providers to a discriminated union. Other schema references and documentation use the UnifiedInferenceProviderEntry name.
Provider configuration snapshots
src/telemetry/configuration_snapshot.py, tests/unit/telemetry/*
Snapshots include skip_model_discovery and mask provider config values. Telemetry fixtures and tests use typed provider entries and check the masked value.

Merge Risk: 🟠 High · up to 823c3

Several newly supported provider configurations cannot produce the intended runtime configuration, and Bedrock synthesis fails outright. Fix these integration failures and the stale schema before merging.

Full details: Security And Secret Handling

Explanation

Plaintext provider credentials remain exposed. The PR adds api_key: Optional[str] at src/models/config.py:768,776,803-807,814,820; these fields are not SecretStr. The loader resolves ${env.*} values before model construction at src/configuration.py:47-59,129-152. Startup logs the full configuration at src/lightspeed_stack.py:187-189, and ConfigurationResponse returns the full Configuration at src/app/endpoints/config.py:39-78 with no credential exclusion (src/models/api/responses/successful/configuration.py:17). The configuration dump also serializes the model at src/models/config.py:4083-4097. The generated schemas expose each credential as a normal string without password or write-only metadata. Telemetry masks config, but that does not protect logs, /config, or configuration dumps.

Resolution

Use SecretStr for every provider credential and token field, including OpenAI, Azure, Bedrock, vLLM, and WatsonX. Add password/write-only schema metadata. Unwrap secrets only at the provider request boundary. Redact or exclude provider credentials from ConfigurationResponse, startup logging, and configuration dumps. Add tests that load environment-backed credentials and assert logs, /config, serialized configuration, and schemas do not expose plaintext values.

match the current models; commit the generated output without manually editing
schema blocks.
- Around line 12887-12897: Update api_key in OpenAIInferenceProviderConfig,
AzureInferenceProviderConfig, BedrockInferenceProviderConfig,
VllmInferenceProviderConfig, and WatsonxInferenceProviderConfig to use
Optional[SecretStr], and unwrap each value only when passing it to the provider
client. Regenerate the OpenAPI schema so the fields are marked as passwords and
write-only.

Review comments at @src/models/config.py:
- Line 768: Change the api_key fields in the OpenAI, Azure, Bedrock, vLLM, and
WatsonX configuration models from Optional[str] to Optional[SecretStr], matching
existing credential fields. Update synthesizers that consume these values to
call get_secret_value() before using the key.
- Around line 732-738: Update the dictionary normalization flow to assign
provider_model_id as name whenever normalized.get("name") is falsy, rather than
using setdefault, which preserves an existing None value. Keep truthy supplied
names unchanged.

setdefault keeps an existing name: None key. The input {"name": None, "provider_model_id": "x"} then fails with a type error, and the documented default never applies. The same happens with name: "".

852-860: Do not replace an explicit empty id with the type default.

data.get("id") is None handles only a missing key or a null value. Those cases are correct. An id that is empty or contains only whitespace still goes to validate_id and fails, which is also correct. No change is needed.


2101-2116: 🗄️ Data Integrity & Integration

No provider ID mismatch occurs in the synthesis path.

The runtime synthesizer reads the raw YAML configuration, not InferenceConfiguration.model_dump(). When id is omitted, _emitted_provider_id therefore applies the intended sentence_transformers to sentence-transformers conversion. Explicit IDs are emitted unchanged, so the proposed my_vllm versus my-vllm collision does not occur either.

12813-12823: Duplicate: plain-string api_key fields remain unmasked.

api_key is still type: string with no format: password / writeOnly in the OpenAI, Azure, Bedrock, vLLM, and WatsonX provider configs. Other secrets in this file use those markers, for example OgxConfiguration.api_key and AzureEntraIdConfiguration. GET /v1/config can therefore return these keys in plain text. Change the model fields to Optional[SecretStr], then regenerate the schema.

A prior review reported that the Spectral CI drift check fails for this file. Run uv run scripts/generate_openapi_schema.py docs/devel_doc/openapi.json and commit the output.
