Agentic harness for theoretical physics research

Hi everyone, at Hugging Face we've been developing agentic harnesses for various domains and today we're releasing physics-intern to tackle research-level problems in theoretical physics. It's a multi-agent framework which we designed to mimic the research process and decomposes the work into several focused tasks that are dispatched to dedicated subagents (computing, reviewing claims, challenging the research strategy...) Using the physics-intern, we were able to double the performance of Gemini models on the CritPt benchmark and set a new SOTA compared to models like GPT-5.5 Pro, while being significantly cheaper :) We wrote up how our framework was built in a blog post and hope it's useful for the community to build on: [https://huggingface.co/spaces/huggingface/physics-intern](https://huggingface.co/spaces/huggingface/physics-intern)
