OpenAI’s Latest Embedding Models and API Innovations

OpenAI's latest update introduces revolutionary embedding models like text-embedding-3-small and text-embedding-3-large, significantly enhancing AI capabilities. These models offer superior performance at reduced costs, marking a milestone in AI technology and accessibility​​​​​​​​​​.

OpenAI has recently launched a groundbreaking update to its AI technologies, including the introduction of advanced embedding models and significant API improvements. This update marks a substantial leap forward in the capabilities and efficiency of AI models, offering developers and users a richer and more versatile toolset.

Breakthrough in Embedding Models: text-embedding-3-small and text-embedding-3-large

Enhanced Performance and Efficiency

The new generation of embedding models, namely text-embedding-3-small and text-embedding-3-large, stands at the forefront of this update. These models have shown remarkable improvements in performance. The text-embedding-3-large model, for instance, has significantly increased its average score on the MIRACL benchmark from 31.4% to 54.9% and on the MTEB benchmark from 61.0% to 64.6%. This enhancement is indicative of its superior ability in multi-language retrieval and English tasks, setting a new standard in the field.


Remarkably, OpenAI has managed to reduce the cost of using these models, making them more accessible to a wider range of users and developers. The pricing for text-embedding-3-small has been slashed by 5X compared to its predecessor, text-embedding-ada-002. Similarly, the text-embedding-3-large is priced attractively at $0.00013 per 1k tokens, further democratizing access to high-quality AI tools.

Flexibility with Embedding Sizes

A key feature of these new models is their ability to adjust embedding sizes. Users can now trade off between performance and cost-effectiveness by shortening the embeddings, a feature that maintains the concept-representing properties of the embeddings while offering flexibility in their application.

GPT-3.5 and GPT-4 Turbo: Enhanced Models and Reduced Pricing

GPT-3.5 Turbo

Alongside the embedding models, OpenAI is set to introduce an updated version of the GPT-3.5 Turbo model, gpt-3.5-turbo-0125, with significant price reductions. This model promises higher accuracy and improved functionality, including a fix for a text encoding issue in non-English languages.

GPT-4 Turbo

The GPT-4 Turbo model has also been updated, continuing to offer its powerful capabilities at lower costs. It has been increasingly adopted by developers due to its comprehensive knowledge base, larger context windows, and cost-efficiency.

Future-Oriented API Enhancements

OpenAI’s commitment to continuous improvement is further reflected in the enhancements made to their API. The introduction of new API usage management tools allows developers greater control and insight into their API usage. These tools include the creation of multiple API keys with different permissions and scopes, and a detailed monitoring system for usage and billing.


OpenAI’s latest update represents a significant milestone in AI development. By offering more powerful, cost-effective, and flexible models, OpenAI continues to push the boundaries of what’s possible in AI, paving the way for innovative applications across various fields. This update not only enhances the technical capabilities of AI models but also makes them more accessible and user-friendly, encouraging broader adoption and experimentation in the AI community.
