Mixedbread
Multimodal embedding and search APIs — state-of-the-art retrieval models, 100+ languages, sub-200ms latency, supports text, images, audio, video, and code.
About Mixedbread
Mixedbread provides embedding and search APIs across modalities — text, images, audio, video and code through one retrieval surface, across a hundred-plus languages. It is infrastructure, not a product: you send content, you get vectors and ranked results. The problem it addresses is that retrieval quality decides whether a RAG system is useful, and running your own embedding models carries an operational cost few teams account for.
We track it rather than run it. We list it as the candidate for when retrieval has to cross modalities — searching images or recordings alongside text — where general-purpose text embeddings run out.
OpenAI and Cohere embeddings are the defaults, well documented and easy to swap. Voyage AI is retrieval-focused and worth benchmarking against directly. Jina AI covers similar multimodal ground with open weights you can host yourself. Storage is a separate call: Pinecone, Weaviate or Qdrant for a dedicated vector database, or pgvector in a Postgres you already run. Our recommendation is unglamorous — if your corpus is English text of modest size, pgvector plus a mainstream model is good enough. Reach for a specialist when multimodal retrieval is the real requirement, and benchmark on your own data, because published retrieval numbers rarely transfer.
