Model ID: `text-embedding-3-small`

text-embedding-3-small is our improved, more performant version of our ada embedding model.
Embeddings are a numerical representation of text that can be used to measure the relatedness between two pieces of text.
Embeddings are useful for search, clustering, recommendations, anomaly detection, and classification tasks.

## Model details

- Default snapshot: `text-embedding-3-small`

## Rate limits

Rate limits ensure fair and reliable access to the API by placing specific caps on requests, tokens, audio duration, or other usage within a given time period. Your usage tier determines how high these limits are set and automatically increases as you send more requests and spend more on the API.
