Why
BYOM models exposed through an OpenAI V1-compatible Chat Completions API may return provider-specific tool-call metadata that must be included in subsequent requests. The client currently loses these fields when converting responses into LangChain messages, causing multi-turn tool execution to fail for providers that require the original metadata.
