Hi, I'm Bingran 👋

📍 Berkeley | 🎓 PhD Candidate @ UC Berkeley | 💻 Agent Evaluation | ⚛️ Experimental AMO Physics

I build reliable AI systems and run trapped-ion experiments in atomic, molecular and optical physics. This page is a short snapshot of projects and papers I've been lucky to work on across both tracks.

💻 Agent Evaluation

How I Build

Current Focus

• 🧪 Agent evaluation and skills-based benchmarking
• 🧭 Deterministic environments for testing long-horizon workflows
• 🛠️ Applied AI systems that operate across existing tools

Selected Work

• ⚛️ FrontierPhysics - FrontierPhysics is an open benchmark measuring whether AI agents can carry out authentic, specialist-level physics research.
• 🌊 BenchFlow - BenchFlow is a frontier environment lab. We build the environments AI agents learn in. We ship SkillsBench, ClawsBench, PostTrain, and the runtime.
• 📐 SkillsBench - SkillsBench evaluates how well skills work and how effective agents are at using them.
• 🌲 first-tree (repo) - Open-source agent orchestration for engineers. Put Claude Code, Codex, Cursor and your own agents on one backlog — parallel runs on your keys, review before merge, everything lands as a pull request.
• 🧠 DeepTutor - DeepTutorZotero is a research sources manager based on Zotero, with amazing AI capability powered by DeepTutor.
• 🐈 mews - Represent you to finish all the work, when you are sleeping.
• 🦞 smolclaw - High resolution mock environments for testing and improving claw like agents
• 😜 SBTI CLI - SBTI CLI - Test SBTI for your agents.

Selected Papers

• 📑 NeurIPS 2026 · SkillsBench: Benchmarking How Well Agent Skills Work Across Diverse Tasks
• 📑 COLM 2026 · ClawsBench: Evaluating Capability and Safety of LLM Productivity Agents in Simulated Workspaces
• 📑 arXiv · BenchShield: Formal Model-Backed Instrumentation for Reward Integrity in LLM-Agent Evaluation Infrastructure
