OpenAI Unveils Advanced Embedding Models with Cost-Effective Solutions

OpenAI announced the release of new embedding models and API updates, including improved performance, cost reduction, and diverse sizing options.

OpenAI has introduced a significant update to its range of embedding models and API tools, marking a remarkable advance in the field of artificial intelligence. This article provides a comprehensive overview of the new models, their implications, and the impact they have on developers and users.

Introducing new embedding models

OpenAI has revealed two new embedding models called text-embedding-3-small and text-embedding-3-large. Embeddings are sequences of numbers representing concepts in content such as natural language or code, which make it easier for models and machine learning algorithms to understand the relationships between different elements. The new models offer a variety of sizes – 512, 1536 for the small model and 256, 1024 and 3072 for the large model – to meet different computing needs and performance requirements.

Cost effectiveness

A distinctive feature of this update is the significant cost reduction. The new models are up to 80% lower prices than the previous models. This pricing strategy aims to make advanced AI tools more accessible to a wider range of developers and users, encouraging innovation and creativity in AI applications.

Technical challenges and solutions

Introducing new models of different sizes presents certain challenges, especially for developers using pgvector-extensions to store embeds. The main concern is how to manage multiple vector dimensions in the same database table while maintaining efficient query mechanisms. Strategies to deal with this include padding existing vectors to fit the maximum dimensions required and creating multiple columns or tables for each dimension size. These approaches, while not without their challenges, reflect the evolving nature of AI development and the need for adaptive database management practices.

A wider meaning

The release of these models is more than a technical update; it marks a shift in OpenAI’s approach to making AI more accessible and cost-effective. By lowering economic barriers to entry, OpenAI promotes wider adoption of AI technologies, potentially leading to more innovative uses and applications across industries.


New OpenAI embedding models and API updates represent a significant step forward in the AI ​​industry. By offering more efficient, flexible and cost-effective solutions, they pave the way for wider experimentation and application of AI technologies. As the AI ​​landscape continues to evolve, these updates underscore the importance of continued innovation and accessibility in the field.
