Qwen3 Reranker 8B is a reranking model from Alibaba, part of the newly launched Qwen3 Embedding series and built on the Qwen3 foundation model. Alibaba's announcement claims the series achieves leading results across text embedding and reranking benchmarks and that its rerankers sharpen search relevance in text retrieval. The model is built for retrieval work: given a query and candidate documents, it outputs relevance scores, supporting multilingual, cross-lingual, and code retrieval across over 100 languages.

}Frequently asked questions
Running locally
Qwen3 Reranker 8B needs an estimated 6.1 GB of VRAM at Q4, 10.3 GB at Q8, and 18.9 GB at FP16. These figures are estimates based on the 8B parameter count, covering weights plus about 15% and 0.5 GB for a short context.
Yes. A 24 GB GPU fits FP16 at an estimated 18.9 GB, a 16 GB or 12 GB GPU fits Q8 at an estimated 10.3 GB, and an 8 GB GPU fits Q4 at an estimated 6.1 GB.
Yes, at Q4, whose estimated VRAM is 6.1 GB. Assuming macOS lets the GPU use about 75% of unified memory, the smallest common Mac memory size that fits Q4 is an estimated 16 GB.
