 "summary": "jina-embeddings-v2-small-en: structural change at 8eac7ec (2023-10-19)",
 "details": "jina-embeddings-v2-small-en: vocab_size changed from 30522 to 30528; the embedding and output head change shape, so adapters and merges made against the old vocabulary no longer load cleanly; derived parameters 32.4M to 32.4M (+3.1K, +0.00 GB of bf16 weights) (2023-10-19).\n\nRepository: https://huggingface.co/jinaai/jina-embeddings-v2-small-en. Revisions from 8eac7ec07775c72f94b7012149aa5c87d80a73cf onward carry this change; a pin at cb8edc5e5c8037c9c9613deb2d91ddc21c1d1b56 or earlier does not.\n\nChanged keys:\n- vocab_size: 30522 -> 30528 (structural)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
