RaDeR, are a set of reasoning-based dense retrieval and reranker models trained with data derived from mathematical problem solving using large language models (LLMs). RaDeR retrievers, trained for mathematical reasoning, effectively generalize to diverse retrieval reasoning tasks in the BRIGHT and RAR-b benchmarks, consistently outperforming strong baselines in overall performance.

How to Get Started with the Model

Run the following code to start a server of the model with vLLM for fast inference.

vllm serve Raderspace/RaDeR_Qwen25-7B_NuminaMath_MATH_allquerytypes \
  --task embed \
  --trust-remote-code \
  --override-pooler-config '{"pooling_type": "LAST", "normalize": true}' \
  --gpu-memory-utilization 0.9 \
  --api-key abc \
  --tokenizer Qwen/Qwen2.5-7B-Instruct \
  --port 8001 \
  --disable-log-requests \
  --max-num-seqs 5000

Follow the code on Github to see how to query the retriever server.
