+# LLM provider chain
+
+This repository resolves the LLM provider in a simple, ordered chain:
+
+1. GitHub Models
+   - Selected when `GITHUB_MODELS_ENDPOINT` or `GITHUB_MODELS_TOKEN` is set.
+   - This is the first choice because it can proxy multiple model backends.
+2. OpenAI
+   - Selected when `OPENAI_API_KEY` or `OPENAI_BASE_URL` is set and GitHub
+     Models is not configured.
+3. Regex fallback
+   - If neither provider is configured, the provider is inferred by regex
+     matching on the model identifier (see `langchain_analysis.detect_llm_provider`).
+   - This is a best-effort heuristic used for logs and UI labels.
+
+## Preferred provider override
+
+Set `PREFERRED_LLM_PROVIDER` to force a specific provider name regardless of
+chain position. This is helpful when the model identifier is ambiguous or when
+running in a mixed environment.
+
+Examples:
+
+- `PREFERRED_LLM_PROVIDER=openai`
+- `PREFERRED_LLM_PROVIDER=github models`
+- `PREFERRED_LLM_PROVIDER=azure openai`

+## Supported LLM providers
+
+The LLM analysis layer recognizes the providers below. These names are the
+canonical labels surfaced in logs and UI.
+
+- GitHub Models
+- OpenAI
+- Azure OpenAI
+- Anthropic
+- Cohere
+- Mistral
+- Google (Gemini/PaLM)
+- Amazon Bedrock
+- Hugging Face
+- Unknown (fallback when no match is detected)
+
+## How the provider is resolved
+
+1. `PREFERRED_LLM_PROVIDER` overrides everything when set.
+2. GitHub Models is selected if `GITHUB_MODELS_ENDPOINT` or
+   `GITHUB_MODELS_TOKEN` is configured.
+3. OpenAI is selected if `OPENAI_API_KEY` or `OPENAI_BASE_URL` is configured.
+4. If no configuration is present, the provider is inferred by regex matching
+   on the model identifier (see `docs/LLM_PROVIDER_CHAIN.md`).
