 "details": "Olmo-3-7B-Instruct: generation defaults changed (max_new_tokens unset to 32768, temperature unset to 0.6, top_p unset to 0.95); a call that does not pass these explicitly now generates differently (2025-11-21).\n\nRepository: https://huggingface.co/allenai/Olmo-3-7B-Instruct. Revisions from 48683dfc961ce0f02f802f109b261d6028d83e0c onward carry this change; a pin at d42dc9de51ee481e02b8a35d8222b86c6d7c5b20 or earlier does not.\n\nChanged keys:\n- generation max_new_tokens: unset -> 32768 (generation-defaults)\n- generation temperature: unset -> 0.6 (generation-defaults)\n- generation top_p: unset -> 0.95 (generation-defaults)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
