We’re excited to announce a brand new embedding mannequin which is considerably extra succesful, value efficient, and easier to make use of. The brand new mannequin, text-embedding-ada-002, replaces 5 separate fashions for textual content search, textual content similarity, and code search, and outperforms our earlier most succesful mannequin, Davinci, at most duties, whereas being priced 99.8% decrease.
Embeddings are numerical representations of ideas transformed to quantity sequences, which make it straightforward for computer systems to know the relationships between these ideas. For the reason that preliminary launch of the OpenAI /embeddings endpoint, many functions have integrated embeddings to personalize, suggest, and search content material.
You’ll be able to question the /embeddings endpoint for the brand new mannequin with two strains of code utilizing our OpenAI Python Library, similar to you can with earlier fashions:
import openai
response = openai.Embedding.create(
enter="porcine buddies say",
mannequin="text-embedding-ada-002"
)
Mannequin Enhancements
Stronger efficiency. text-embedding-ada-002 outperforms all of the previous embedding fashions on textual content search, code search, and sentence similarity duties and will get comparable efficiency on textual content classification. For every activity class, we consider the fashions on the datasets utilized in previous embeddings.
Unification of capabilities. We’ve got considerably simplified the interface of the /embeddings endpoint by merging the 5 separate fashions proven above (text-similarity, text-search-query, text-search-doc, code-search-text and code-search-code) right into a single new mannequin. This single illustration performs higher than our earlier embedding fashions throughout a various set of textual content search, sentence similarity, and code search benchmarks.
Longer context. The context size of the brand new mannequin is elevated by an element of 4, from 2048 to 8192, making it extra handy to work with lengthy paperwork.
Smaller embedding measurement. The brand new embeddings have solely 1536 dimensions, one-eighth the dimensions of davinci-001 embeddings, making the brand new embeddings less expensive in working with vector databases.
Lowered worth. We’ve got lowered the value of latest embedding fashions by 90% in comparison with previous fashions of the identical measurement. The brand new mannequin achieves higher or related efficiency because the previous Davinci fashions at a 99.8% lower cost.
General, the brand new embedding mannequin is a way more highly effective instrument for pure language processing and code duties. We’re excited to see how our clients will use it to create much more succesful functions of their respective fields.
Limitations
The brand new text-embedding-ada-002 mannequin isn’t outperforming text-similarity-davinci-001 on the SentEval linear probing classification benchmark. For duties that require coaching a light-weighted linear layer on prime of embedding vectors for classification prediction, we propose evaluating the brand new mannequin to text-similarity-davinci-001 and selecting whichever mannequin offers optimum efficiency.

Examples of Embeddings API in Motion
Kalendar AI is a gross sales outreach product that makes use of embeddings to match the best gross sales pitch to the best clients out of a dataset containing 340M profiles. This automation depends on similarity between embeddings of buyer profiles and sale pitches to rank up best suited matches, eliminating 40–56% of undesirable focusing on in comparison with their previous method.
Notion, the web workspace firm, will use OpenAI’s new embeddings to enhance Notion search past at the moment’s key phrase matching techniques.
