AI Model Families: Pick an Embedding Model You Can Live With
Embedding choice is hard to reverse — re-embedding millions of documents is expensive — so optimize for retrieval quality on your data and provider stability.
10 min · Reviewed 2026
The premise
Once your corpus is embedded, switching costs real money and time; pick the embedding model on retrieval quality measured on your queries, not provider marketing.
What AI does well here
Build a small retrieval-quality test from real queries
Score candidates on recall@k for your data
Estimate switch cost (re-embed at current corpus size)
Recommend dimension and quantization tradeoffs
What AI cannot do
Predict provider price or deprecation
Replace tuning your chunking strategy
Eliminate the need for hybrid retrieval
