About Qwen3 Embedding 8B

Qwen3 Embedding 8B is Alibaba's flagship open-weight embedding model under Apache 2.0: 8B parameters, a 32K-token input window, and vectors of up to 4096 dimensions — with Matryoshka support down to 32, so vector size matches what your store can afford.

It is instruction-aware: a one-line task instruction steers the same model toward retrieval, classification, clustering, or code search, across 100+ natural and programming languages — no fine-tuning required.

It ranked #1 on the MTEB multilingual leaderboard at release (score 70.58) and posts 81.22 on MTEB-Code — retrieval quality that carries production RAG pipelines and semantic search.

#1MTEB multilingual at release

Score 70.58 on the leaderboard spanning retrieval, classification, and clustering.

4096embedding dimensions

Matryoshka support scales vectors down to 32 dims to cut storage and search cost.

100+languages supported

One embedding space across natural and programming languages.

Key capabilities

Qwen3 Embedding 8B is the retrieval side of a production RAG stack — search, deduplication, and classification that stay accurate across languages and code.

Multilingual retrieval

Cross-language matching in 100+ languages — query in German, retrieve English documents, and vice versa.

Code search

81.22 on MTEB-Code — natural-language queries over repositories, snippets, and documentation.

Instruction-aware vectors

A one-line task instruction tunes embeddings for retrieval, classification, or clustering — no fine-tuning required.

Matryoshka dimensions

Truncate 4096-dim vectors down to 32 with graceful quality falloff — match vectors to your store budget.

Where this model fits

Best for
  • Semantic search and RAG retrieval

    MTEB-topping retrieval quality feeds cleaner context to any generation model in the catalog.

  • Multilingual search across 100+ languages

    One embedding space for global content — query in one language, match documents in another.

  • Code search and documentation retrieval

    81.22 on MTEB-Code — natural-language queries over repositories, snippets, and docs.

  • Clustering, dedup, and classification

    Instruction-aware vectors adapt to the task, and Matryoshka dimensions cut storage where scale demands it.

Avoid for
  • Chat, generation, or tool calling

    Outputs vectors, not text. Pair it with a generation model such as Qwen 3.6 35B-A3B for the answering side of RAG.

  • Inputs beyond 32K tokens

    Chunk longer documents before embedding — 32K is the per-request ceiling.

  • Image or audio embeddings

    Text only. Use a multimodal embedder for cross-modal search.
