An open-source AI community event on reinforcement learning for agentic systems, hosted by GitHub and Hugging Face. Join the open-source community at GitHub in San Francisco for an evening with researchers and builders exploring how AI agents are trained and evaluated. We will look beyond single-turn RL to multi-step, environment-driven training: reward design, rollouts, benchmarks, and the practical gap between training gains and real-world agent behavior. What to expect Short, 10-minute talks with Q&A, followed by a closing panel on what works in RL for agents, where the bottlenecks are, and what the open-source ecosystem needs next. Speakers:

  • Ben Burtenshaw (HF)
  • Govind Kamtamneni (Microsoft)
  • Victor Barres (Mercor)
  • Zach Wentz (Reflection)
  • Tao Lin (RadixArk)
  • Xiangyi Li (Benchflow) Who should attend ML practitioners, agent builders, and RL researchers. Thursday, October 22, 2026 · 6–9pm Pacific GitHub, San Francisco
