New embedding models and API updates

# New embedding models and API updates Source: [https://openai.com/index/new-embedding-models-and-api-updates/](https://openai.com/index/new-embedding-models-and-api-updates/) `text\-embedding\-3\-small`is our new highly efficient embedding model and provides a significant upgrade over its predecessor, the`text\-embedding\-ada\-002`model released in[December 2022⁠](https://openai.com/index/new-and-improved-embedding-model/)\. **Stronger performance\.**Comparing`text\-embedding\-ada\-002`to`text\-embedding\-3\-small`, the average score on a commonly used benchmark for multi\-language retrieval \([MIRACL⁠\(opens in a new window\)](https://github.com/project-miracl/miracl)\) has increased from 31\.4% to 44\.0%, while the average score on a commonly used benchmark for English tasks \([MTEB⁠\(opens in a new window\)](https://github.com/embeddings-benchmark/mteb)\) has increased from 61\.0% to 62\.3%\. **Reduced price\.**`text\-embedding\-3\-small`is also substantially more efficient than our previous generation`text\-embedding\-ada\-002`model\. Pricing for`text\-embedding\-3\-small`has therefore been reduced by 5X compared to`text\-embedding\-ada\-002`, from a price per 1k tokens of $0\.0001 to $0\.00002\. We are not deprecating`text\-embedding\-ada\-002`, so while we recommend the newer model, customers are welcome to continue using the previous generation model\. A new large text embedding model:`text\-embedding\-3\-large` `text\-embedding\-3\-large`is our new next generation larger embedding model and creates embeddings with up to 3072 dimensions\. **Stronger performance\.**`text\-embedding\-3\-large`is our new best performing model\. Comparing`text\-embedding\-ada\-002`to`text\-embedding\-3\-large`: on MIRACL, the average score has increased from 31\.4% to 54\.9%, while on MTEB, the average score has increased from 61\.0% to 64\.6%\.
