OpenResearcher-30B-A3B Overview

OpenResearcher-30B-A3B is an agentic large language model designed for long-horizon deep research fine-tuned from NVIDIA-Nemotron-3-Nano-30B-A3B-Base-BF16 on 96K OpenResearcher dataset with 100+ turns. The dataset is derived by distilling GPT-OSS-120B with native browser tools. More info can be found on the dataset card at OpenResearcher dataset.

The model achieves an impressive 54.8% accuracy on BrowseComp-Plus, surpassing performance of GPT-4.1, Claude-Opus-4, Gemini-2.5-Pro, DeepSeek-R1 and Tongyi-DeepResearch.
