Why are similarity scores lower with text-embedding-3-small?

I hope you’re right—and I agree that from an infrastructure and cost‑efficiency point of view, ada‑002 likely has a strong profile. I also anticipate that ada‑002 will stick around until a genuinely better replacement is available. For now, we’re sticking with ada‑002 where performance matters most, though we may still need to plan a move to 3‑small, since unexpected model availability changes are risky for production systems that rely on stable embeddings
