🤔Want a principled way to RL your diffusion model? Check Data-regularized Reinforcement Learning (DDRL)! Post-train @nvidia #Cosmos World Foundation models with a million GPU hours! 🤯 Novel formulation ➡️ Theoretically integrates SFT into RL ➡️ Robust to Reward Hacking 🛑 Details: research.nvidia.com/labs/dir/ddrl/ #DDRL #Diffusion #RL #NVIDIA #Cosmos


We raised $28M seed from Threshold Ventures, AIX Ventures, and NVentures (Nvidia's venture capital arm) —alongside 10+ unicorn founders and top AI researchers— to build reasoning models that generate real-time simulations and games. Models are bottlenecked by practical simulations that can act as Reinforcement Learning environments. Human self-expression is bounded by tools that let us create alternate realities. At Moonlake, we are building a future where anyone can create interactive worlds, bring their child-like wonder to life, learn within them, and most importantly, share experiences with people we care about.

Today is my last day at @StabilityAI . It’s incredible how quickly the past year has flown by! I’m deeply grateful for the opportunity to work alongside such talented and inspiring colleagues. A special thank you to Christian @chrlaf for trusting me to lead the speech research direction as a new graduate. I’m proud of my team and all that we’ve achieved together. (Psst... Stable Codec will be released very very soon!) I’ll truly miss Stability AI and the amazing team here. Excited to share my next steps with you all soon! ❤️
