 "details": "Qwen3.8-27B-FP8: generation defaults changed (temperature 0.6 to 1); a call that does not pass these explicitly now generates differently (2026-08-13).\n\nRepository: https://huggingface.co/Qwen/Qwen3.8-27B-FP8. Revisions from 5c9be11f91f4d57a79e47ba40839003766792302 onward carry this change; a pin at e4f7558fd8506eda3a43c9e9dff1d01ba855488a or earlier does not.\n\nChanged keys:\n- generation temperature: 0.6 -> 1 (generation-defaults)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
