    On Saturday, we brought together 200+ founders, researchers, and engineers for RL IRL at Y Combinator HQ! At Osmosis (YC W25), our belief is that RL is the missing piece for AI agents that truly learn and work - but despite all the recent attention on RL, there weren't any major in-person events focused on how to actually *apply* RL. We wanted to fix this, so we brought together some of our friends to talk about how they're using RL today! The response was overwhelming! We had over 800 registrations and were literally at max capacity at YC. The talks covered everything from how to set up products for RL, to how to design RL training loops, to how companies build & scale RL environments today: -Osmosis (YC W25) and Greptile - Designing RL-Ready Products -ZeroEntropy (YC W25) - Scaling Reranker Models with RLAIF -Reducto - RL for Ill-Defined Objectives -hud (YC W25) and The LLM Data Company (YC X25) - Building & Scaling RL Environments -Encord - Data Scaffolding for Multimodal RL -Turing - RL Environments for the Enterprise *Link to thread of summaries + session recordings is in the comments.* Thank you so much to our co-organizers that helped bring RL IRL together, and a special thank you to all the attendees that came! We'll be hosting more RL-focused events - in the meantime, if you're interested in learning about how to use RL for your own use cases, don't hesitate to reach out!

    We’re excited to finally launch Osmosis (YC W25): we help companies build AI agents that actually work. With reinforcement learning that enables fine-tuned models to outperform foundation models, we make AI agents better, faster, and cheaper. We’ve raised $6.3M in seed funding, co-led by CRV and Audacious Ventures, along with angels like Paul Graham (Y Combinator), Guillermo Rauch (Vercel), Misha Laskin (Reflection AI), Erik Bernhardsson (Modal Labs), Shane Gu (Google DeepMind), and many more. My co-founder Baiqing (Andy) L. and I met over a decade ago in middle school. I’ve always known that I wanted to start a company with him. While I co-founded & sold my first company in undergrad, Andy speedran college and became the youngest tech lead at TikTok. We’re just getting started - we’ve got even more projects (like our open-source models) coming soon, and I can’t wait to share. If you're interested in applying reinforcement learning for your own product, book a demo in the comments!

    I met my co-founder Kasey Z. in middle school. He founded and sold his first company during college, while I joined TikTok early-on to scale real-time recommendations through the pandemic. Now, a decade+ after we first met, I’m excited to officially unveil Osmosis: a comprehensive platform that helps company build AI agents that actually work. The reason why TikTok won was because the product learned from users in real-time. We’re applying the same principles to AI agents now. We’ve raised $7M from Y Combinator and some of the best investors, built an amazing team, and we’re just getting started. Learn more about Osmosis here: osmosis.ai
