 "summary": "Llama-3.2-3B-Instruct: tokenizer change at c64b6bc (2025-01-16)",
 "details": "Llama-3.2-3B-Instruct: pad token unset to 128004; batched training masks a different id; generation defaults changed (max_length unset to 131072); a call that does not pass these explicitly now generates differently (2025-01-16).\n\nRepository: https://huggingface.co/unsloth/Llama-3.2-3B-Instruct. Revisions from c64b6bcd612f3348d4ae448944518845e6478eeb onward carry this change; a pin at cfe38f8f38afea8b9f9cc66f634bf53c321cf426 or earlier does not.\n\nChanged keys:\n- pad_token_id: unset -> 128004 (tokenizer)\n- generation max_length: unset -> 131072 (generation-defaults)\n- generation pad_token_id: unset -> 128004 (tokenizer)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
