About
The standard benchmark for text and multimodal embedding models, covering retrieval, classification, clustering, semantic similarity and reranking rather than a single retrieval score. The 2025 MMTEB expansion extended it to a large multilingual task set, and results are published on an interactive HuggingFace leaderboard. Apache-2.0 and Python, maintained by the embeddings-benchmark organisation.
Why it made the leaderboard
Retrieval quality is set by the embedding model, and MTEB is how you choose one: it scores across retrieval, classification, clustering, similarity and reranking instead of a single number, so a model that wins on retrieval but collapses on clustering has nowhere to hide. The MMTEB expansion extends the same treatment across many languages.
