feat: add llmman as an OpenAI-compatible provider - #7217
Conversation
llmman (https://github.com/llmmanorg/llmman) runs local models distributed as OCI artifacts and serves an OpenAI-compatible API on port 17434. It needs no API key, so it follows the Ollama entry rather than the hosted ones. LLMMAN_HOST is a bare host:port value, so it also joins the /v1 base-URL normalization; that helper is renamed since it is no longer Ollama-specific. Routing is registered in LLM as well as the provider registry, so both llmman/<model> and provider="llmman" reach OpenAICompatibleCompletion instead of falling back to LiteLLM. Closes crewAIInc#7216 Signed-off-by: Eric Curtin <eric.curtin@docker.com>

Suggested reviewers: Merge Risk: 🔵 Low · up to This PR adds llmman as a local OpenAI-compatible provider, but the generated CLI configuration may not change the runtime endpoint, non-loopback HTTP endpoints may transmit credentials without an explicit transport policy, and empty model names plus environment-dependent test setup can cause bounded correctness or test reliability issues.

Write LLMMAN_HOST for llmman. The CLI writes API_BASE unchanged to .env, but OpenAICompatibleCompletion resolves the llmman endpoint only from LLMMAN_HOST. Therefore, changing the generated API_BASE does not change the runtime endpoint. Use LLMMAN_HOST or add an explicit translation.

Reject an empty llmman model after prefix parsing.
_validate_model_in_constants("", "llmman") falls through to _matches_provider_pattern, which returns True for llmman. The factory can therefore construct OpenAICompatibleCompletion with model=""; its model: str field has no non-empty validation. Add a non-empty model_part guard before the permissive local-provider match.

Make the default URL assertion independent of LLMMAN_HOST.
This test reads the process environment but asserts the default URL. A developer or CI job that defines LLMMAN_HOST will make the test fail even when the environment override works correctly. Clear LLMMAN_HOST or set it to an empty value before constructing the LLM.
