Revisions from 7937954a98e0d2fe2baa2aa0195f02d87d4e8389 onward carry this change; a pin at cc77892181284701d11262109d3b85b4fd870813 or earlier does not.\n\nChanged keys:\n- tokenizer model_max_length: unset -> 77 (tokenizer)\n- tokenizer tokenizer_class: unset -> CLIPTokenizer (tokenizer)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
