 "summary": "Kimi-VL-A3B-Instruct: tokenizer change at 7a3c132 (2025-04-20)",
 "details": "Kimi-VL-A3B-Instruct: EOS declared as [163585] (was unset); generation that relied on the library default now stops on this token; BOS declared as 163584 (was unset); pad token unset to 163838; batched training masks a different id (2025-04-20).\n\nRepository: https://huggingface.co/moonshotai/Kimi-VL-A3B-Instruct. Revisions from 7a3c132a7b0f1f1677f5a72f258bd3afded7d357 onward carry this change; a pin at b0b86ff5487fc5b15f6882cb45056918187212aa or earlier does not.\n\nChanged keys:\n- generation bos_token_id: unset -> 163584 (tokenizer)\n- generation eos_token_id: unset -> [163585] (tokenizer)\n- generation pad_token_id: unset -> 163838 (tokenizer)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
