Tianyi Cui	706590c62a	fix: Enable extended thinking support for Claude Haiku 4.5 Claude Haiku 4.5 (claude-haiku-4-5-20251001) supports extended thinking according to Anthropic's official documentation: https://docs.anthropic.com/en/docs/build-with-claude/extended-thinking The model was incorrectly marked as not supporting thinking in the static model definitions. This fix adds ThinkingSupport with the same parameters as other Claude 4.5 models (Sonnet, Opus): - Min: 1024 tokens - Max: 128000 tokens - ZeroAllowed: true - DynamicAllowed: false	2026-02-05 19:03:23 +08:00
