 "details": "Qwen2.5-14B-Instruct-AWQ: the chat template changed and renders differently (tool-call); prompts rendered with the old one no longer match what the model now expects, so cached prompts and eval sets need re-rendering (2024-09-19).\n\nRepository: https://huggingface.co/Qwen/Qwen2.5-14B-Instruct-AWQ. Revisions from 15caf3706c437f72fe4a0b64b4aee94b5e823e9c onward carry this change; a pin at 302d7ea6b811c4c5c6e127a0435f6342dbe9ec72 or earlier does not.\n\nChanged keys:\n- tokenizer chat_template_sha256: d5495a1e5db06111 -> cd8e9439f0570856 (template)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
