OpenAI vs. Open-source Embedding Model Showdown

In today's video, Jacky Liang, developer advocate at Timescale, deep dives into the complex world of embedding models for AI applications, comparing OpenAI's reliable but costly models against high-performing open-source alternatives. Discover how these models measure up on tasks involving text chunks and various question types, from simple to context-based. Learn how pgai Vectorizer simplifies handling multiple models and automates embedding updates within PostgreSQL. Get detailed results from the evaluation of four popular models, along with practical recommendations to help you choose the best model for your specific needs and constraints.
