 "summary": "jina-embeddings-v2-base-code: structural change at 27936d8 (2024-01-25)",
 "details": "jina-embeddings-v2-base-code: vocab_size changed from 61056 to 30528; the embedding and output head change shape, so adapters and merges made against the old vocabulary no longer load cleanly; derived parameters 138.2M to 114.8M (-23.4M, -0.05 GB of bf16 weights); declared dtype \"float16\" to \"float32\" (2024-01-25).\n\nRepository: https://huggingface.co/jinaai/jina-embeddings-v2-base-code. Revisions from 27936d831769514f3107ecd67f9f202d74df59bf onward carry this change; a pin at c157a1f32981e53c466a5a7e27ef09b1cbdedee4 or earlier does not.\n\nChanged keys:\n- dtype: float16 -> float32 (structural)\n- vocab_size: 61056 -> 30528 (structural)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
