fix(fold-xai): use Chat Completions for xAI tool calls - #10
Merged
Conversation
xAI's Responses API (/v1/responses) has incomplete support for streaming tool calls, causing the stream to hang when Grok tries to call tools. Switch fold-xai from @effect/ai-openai (Responses API) to @effect/ai-openai-compat (Chat Completions API), matching the approach fold-opencode already uses for grok models. Also bumps the default model to grok-4.6.
