 "details": "shieldgemma-9b: the chat template text changed; the renderer could not run one of the two versions, so whether rendered prompts changed is not known (2024-08-28).\n\nRepository: https://huggingface.co/google/shieldgemma-9b. Revisions from 8edd323adfa23ca6e1d824aa79594e160aff7b15 onward carry this change; a pin at 5b50a60d91f0a79236f5e8e5133e9135400f1e89 or earlier does not.\n\nChanged keys:\n- tokenizer chat_template_sha256: 859f857e74986e31 -> 19acd33317c8f502 (template)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
