- Return raw Response from createChatCompletions instead of parsing SSE in the service layer, allowing handlers to pipe streams directly - Pipe OpenAI-compatible streams through a monitoring TransformStream for TTFT and throughput logging without re-serializing - Anthropic /messages handler now parses SSE at the handler level where it needs to translate events - Normalize max_completion_tokens to max_tokens for upstream compat - Set Bun idleTimeout to 0 to prevent premature SSE connection kills (default 10s was dropping long-running LLM streams) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
