Toast 1: A New Embedding Model That Rivals OpenAI at a Fraction of the Cost
Toast 1: A New Embedding Model That Rivals OpenAI at a Fraction of the Cost Mixedbread AI announced Toast 1, a new embedding model that claims to match or exceed OpenAI's text-embedding-3-large on standard benchmarks while being significantly cheaper to run.

Mixedbread AI has unveiled Toast 1, a new embedding model that challenges OpenAI's text-embedding-3-large while being more cost-effective. Embedding models translate text into numerical vectors that capture semantic meaning. They are crucial for applications like semantic search, RAG, clustering, classification, and recommendation systems.
Toast 1 boasts quality and cost advantages over OpenAI's model. Benchmark results show Toast 1 scoring slightly higher on MTEB tasks such as retrieval, STS, classification, and reranking. Its multilingual support covers over 50 languages, and it offers variable dimensionality for cost optimization. Toast 1's single-model approach with Matryoshka embeddings allows flexible use of different dimensionalities.
As embedding models become integral to AI applications, Toast 1 offers a compelling open-weight alternative to OpenAI's costly offering.
