 "details": "Qwen2.5-Coder-3B-Instruct: EOS changed from 151643 to 151645; anything fine-tuned or served against the old value stops at a different token (2024-11-09).\n\nRepository: https://huggingface.co/Qwen/Qwen2.5-Coder-3B-Instruct. Revisions from 93d7dcdb8e992d75808533b977e5753266d09b3e onward carry this change; a pin at 4083ed00af13fec5298720e9cb005e210f70ac51 or earlier does not.\n\nChanged keys:\n- eos_token_id: 151643 -> 151645 (tokenizer)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
