Qwen3-Reranker-8B
This repository contains Qwen/Qwen3-Reranker-8B
together with a Furiosa Executable Bundle (FXB) for running it on
FuriosaAI RNGD with Furiosa-LLM.
The same model also runs on other frameworks (such as Sentence Transformers,
vLLM, and Transformers); for usage with those, see the upstream
Qwen/Qwen3-Reranker-8B model card.
Overview
Qwen3-Reranker-8B is the 8B reranking model in the Qwen3-Reranker series,
built on the Qwen3 dense transformer backbone. Given a query and a set of
candidate documents, it produces relevance scores used to reorder retrieval
results β a common second stage in retrieval-augmented generation (RAG) and
search pipelines. Its intended use is the same as the upstream
Qwen/Qwen3-Reranker-8B,
and it is released under the Apache 2.0 License.
- Architecture: Qwen3 (dense)
- Input / Output: Text (query-document pairs) / Relevance score
- Supported Inference Engine: Furiosa LLM
- Supported Hardware: FuriosaAI RNGD
Quantization
No quantization β the model runs in its native BF16 precision.
Parallelism Strategy
On RNGD, Qwen3-Reranker-8B runs with a tensor-parallel size of 8 PEs, which
maps to a single RNGD card (8 PEs per card).
Usage
To run this model with Furiosa-LLM, follow the examples below after
installing Furiosa-LLM and its prerequisites.
You can use the model either online through the OpenAI-compatible server or
offline through the Furiosa-LLM Python API.
Launch the server
The simplest way to serve the model is:
When the server is ready, you will see:
Basic Usage
The server exposes a /v1/rerank endpoint (compatible with the Cohere/Jina
rerank API, also used by vLLM). Send a query and the candidate documents with
curl; the server returns the documents reordered by relevance_score:
You can do the same from Python with the requests library, and pass top_n to
keep only the most relevant documents:
To score query-document pairs directly instead of reranking, the server also
exposes a /v1/score endpoint.
Advanced Usage
For offline use, load the model with the LLM constructor (the FXB shipped in
the repo is discovered automatically) and call score with a query and the
candidate documents to obtain relevance scores:
