OpenAI's models cover a wide range of commerce work, and the embeddings are as useful as the chat models. Embeddings are what let search understand that a customer typing waterproof jacket for hiking should see a hardshell, even though the words do not match.
We use them for semantic search and recommendations, for content generation across large catalogs, and for the internal tools that never get built because they are not quite worth a sprint. We evaluate against your real queries and your real catalog before anything goes live, because relevance that works on a demo and fails on the long tail is worse than no change at all.
