 "summary": "jina-embeddings-v5-text-small: structural change at dab81cb (2026-02-02)",
 "details": "jina-embeddings-v5-text-small: derived parameters 596.0M to 483.0M (-113.0M, -0.23 GB of bf16 weights); context window 40960 to 32768 tokens; model_type \"qwen3\" to \"jina_embeddings_v5\"; a different class is instantiated from the same id (2026-02-02).\n\nRepository: https://huggingface.co/jinaai/jina-embeddings-v5-text-small. Revisions from dab81cb52e4164a72665cb7ac7ef5cf98f8e7561 onward carry this change; a pin at c9756bfc6a062e6d2a993463b28a07aef08ed99d or earlier does not.\n\nChanged keys:\n- max_position_embeddings: 40960 -> 32768 (structural)\n- model_type: qwen3 -> jina_embeddings_v5 (structural)\n\nThis record says what the change does mechanically. It is not a report that anything broke for anyone.",
