A Brooklyn startup with 60 people just raised 2 billion dollars to build AI models as powerful as GPT-4, then release the actual model weights for free—not just API access, but the stuff OpenAI guards like nuclear codes. Reflection AI is led by the core team behind AlphaGo and Google Gemini, using the same reinforcement learning techniques that beat the world Go champion, except now applied to coding agents that write software that actually works with reliability guarantees. Their first frontier model drops soon, trained on tens of trillions of tokens, and it's backed by Sequoia, NVIDIA, Eric Schmidt, and even the White House AI Czar who said the U.S. needs to win the open-source AI race.
