Siddharth Balyan 46fedef07f fix(openrouter): never send reasoning field for adaptive Anthropic models (#43012) ... The previous fix (#42991) only omitted reasoning when it was being disabled. But reasoning-mandatory Anthropic models (Claude 4.6+, fable) 400 with thinking.type.disabled on EVERY tool-continuation turn even when reasoning is enabled: chat_completions never replays signed thinking blocks, so the prior assistant tool_call has no thinking, and OpenRouter resolves "reasoning requested but history has none" by emitting thinking.type.disabled — which these models reject. Result: first turn works, every turn after the first tool call dies (HTTP 400, non-retryable). OpenRouter ignores reasoning.effort for adaptive Anthropic models anyway (the model self-decides), so the reasoning field is pointless for them on every turn and harmful on tool-replay turns. Omit it entirely → adaptive default. - openrouter profile: drop the reasoning field for reasoning-mandatory Anthropic models regardless of enabled/disabled; legacy Anthropic + non-Anthropic models unchanged. - tests: assert omission across enabled/disabled/effort variants; parity tests switched to a non-Anthropic reasoning model (deepseek) since Anthropic 4.6+ no longer carries a reasoning field. Verified live end-to-end: a tool-replay turn on anthropic/claude-fable-5 with reasoning enabled now builds extra_body=None and returns HTTP 200 (was 400).		2026-06-10 00:18:23 +05:30
