Qwen3 Reranker

Alibaba Cloud
open weights / Overall score: 4.0(strong)

Alibaba's Qwen3 reranking line, the cross-encoder half of the Qwen3 Embedding series. The text models (0.6B, 4B, 8B) score a query-document pair over 100-plus languages at 32K context and accept a task instruction. Qwen ships Qwen3-VL-Reranker models that extend the same interface to images and video, but this product is scoped to the text cross-encoders: the category treats a vision-language line as a separate product from the text line, for a vendor's reranker and its embedder alike.

Added 2026-09-11 for the embeddings_retrieval promotion. Scoped to the text cross-encoders. Qwen ships Qwen3-VL-Reranker checkpoints on the same interface, but this category treats a vision-language line as a separate product from the text line, for a vendor's reranker and its embedder alike, so they are excluded from this record on every axis. Community seq-cls conversions (tomaarsen, dolfsai, furiosa-ai) and GGUF/AWQ re-publishers are not counted. Verified 2026-09-11 via the Qwen3-Reranker-4B and Qwen3-VL-Reranker-2B model cards and the QwenLM/Qwen3-Embedding repository.

Openness

3 high confidence
3.0
weights
open(Apache-2.0 ungated safetensors across the three text cross-encoder checkpoints)
data
closed(no training corpus or data-construction scripts released)
code
partial(the Qwen3-Embedding repository's docs/training directory holds a single file, SWIFT.md, which documents fine-tuning through the third-party ms-swift framework rather than releasing a pretraining pipeline)
license
Apache-2.0(OSI)

Apache-2.0 weights and a repository that ships training docs, but no training corpus and no data-construction scripts, so the ladder lands on its open-weights centre of gravity rather than on a data rung.

Adoption

4 high confidence
4.0

3,765,905 downloads in the trailing 30 days across the three text reranker checkpoints - Reranker-4B, Reranker-0.6B and Reranker-8B. The Qwen3-VL-Reranker checkpoints are excluded and are not counted anywhere on the map, which is the same rule qwen3-embedding applies to Qwen3-VL-Embedding: a vision-language line is a separate product from the text line, for a vendor's reranker and its embedder alike. Counting them would give 5,720,864 and the same band. Community seq-cls conversions, GGUF and AWQ re-publishers are excluded.

Capability

4 high confidence
4.0

Rung 4, competitive frontier: current generation, multilingual, long-context and strong on published retrieval numbers across both text and visual-document tasks. Held below the category anchor rather than level with it because harrier-oss holds a measured first place on the public MMTEB v2 table and this line does not, on any single instrument the category treats as primary.
