text-embedding-3-small

text-embedding-3-small provides text vectors for search and relatedness tasks. Its listed token price is lower than both the large v3 model and ada-002.

A small embedding model still allows shorter vectors

Its default output has 1,536 dimensions, and the dimensions parameter can reduce that length. The listed rate is $0.02 per million input tokens. The API supports individual embedding requests and Batch processing.text-embedding-3-small official model documentationOpenAI embedding dimensions and retrieval guide

Inspect retrieval failures before changing models

Practical guidance. For a support knowledge base, compare missed articles, ambiguous terms and multilingual queries. Poor document splitting or weak source material can limit retrieval even with a larger model. Change one part of the retrieval pipeline at a time.
