When it happens, every vector in your index needs to be regenerated.\n- Embeddings from different models are geometrically incompatible, even when dimensions match. There is no shortcut: you have to re-embed.\n- Three production strategies: blue-green index deployment (build a parallel index and cut over), mixed-model indexes with RRF fusion (migrate gradually while keeping both queryable), and embedding space alignment (promising research, but no confirmed production deployments yet).\n- Standard A/B testing is misleading for embedding swaps because the retrieval step itself changes. Use LLM-as-judge for offline validation and canary rollouts with automated rollback.\n- Build for migration from day one: version your embeddings, store the original text alongside the vectors, and keep a retrieval evaluation harness ready. Teams that treat the embedding model as a permanent decision scramble when the deprecation notice arrives.\n \n ","thumbnail_url":"https://img.transistorcdn.com/KyA01h2FD2insgk-wX_xzV6vbJnTNl2BvPYVL-XaI9A/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzQxMjcyLzE2ODM1/ODI0ODgtYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
