 "summary": "mistral-7b-v0.3-bnb-4bit: tokenizer change at ff1aba4 (2024-08-07)",
 "details": "mistral-7b-v0.3-bnb-4bit: pad token unset to 770; batched training masks a different id; generation defaults changed (max_length unset to 32768); a call that does not pass these explicitly now generates differently (2024-08-07).\n\nRepository: https://huggingface.co/unsloth/mistral-7b-v0.3-bnb-4bit. Revisions from ff1aba4d92518713a7366d03d247afb1b0b76a64 onward carry this change; a pin at 6ae0f3056d3ba783295883026e417e8f838a6e9e or earlier does not.\n\nChanged keys:\n- generation max_length: unset -> 32768 (generation-defaults)\n- generation pad_token_id: unset -> 770 (tokenizer)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
