Qwen3-Embedding

Alibaba Cloud
open weights / Overall score: 4.3(strong)

Qwen3-Embedding is Alibaba's text embedding family built on the Qwen3 dense base models and shipped in 0.6B, 4B and 8B sizes. The models cover 100+ natural and programming languages at a 32k context, support Matryoshka output dimensions from 32 up to 4096, and take a task instruction on the query side. They are released alongside a matching Qwen3-Reranker line, so a retrieval stack can use the same family for both the bi-encoder and the cross-encoder stage.

The vendor's own GGUF conversions and the separate Qwen3-VL-Embedding line are excluded from the adoption sum. Verified 2026-09-11 via the Hugging Face model card, the three Hub API records and the QwenLM repository.

license
Apache-2.0(OSI)

Apache-2.0 across every distributed size, which is unusual for a Qwen release and means multi_sku_rule has nothing restrictive to resolve to. What holds it at 3 rather than higher is the other half of the ladder: the training corpus is described in the paper but not published, and the repository carries evaluation and usage code rather than the pipeline that produced the checkpoints.

Adoption

5 high confidence
5.0

12,549,679 downloads in the trailing 30 days across the three shipped embedding checkpoints - 7,806,497 for the 0.6B, 2,489,577 for the 4B and 2,253,605 for the 8B. Excluded from the sum: the vendor's own GGUF conversions of the same three checkpoints (another 173k) and the separate Qwen3-VL-Embedding line, which is a different product. Level 5 here is measured, not inferred.

Capability

4 high confidence
4.0

Rung 4, the competitive frontier. Qwen3-Embedding-8B held first place on the multilingual MTEB leaderboard at release and still posts 70.58, with 100+ languages, a 32k context and Matryoshka dimensions - everything the rung asks for. It is one below Harrier-OSS because the anchor's 74.3 has since displaced it from the top of the same table, not because anything about the Qwen line has weakened.
