Reflection AI lands $2B to build an open-source AI champion

Brooklyn-based Reflection AI has closed a staggering $2 billion funding round at an $8 billion valuation. The round, led by chipmaker and AI kingmaker Nvidia, marks a 15x valuation jump in just seven months for the startup, which aims to build what it calls “superintelligent autonomous coding agents.”

Founded in early 2024 by a duo of DeepMind heavyweights—Misha Laskin, who led reward modeling for Gemini, and Ioannis Antonoglou, a co-creator of AlphaGo—Reflection AI is positioning itself as a uniquely American, open-source counterweight to the industry’s giants. With a team of around 60 researchers poached from labs like OpenAI and DeepMind, the company is making a direct play against the closed, proprietary models of its rivals and the rapid rise of Chinese open models like DeepSeek.

An open-source counterweight

The core thesis at Reflection AI is that the future of AI shouldn’t be locked inside a handful of corporate labs. The company argues this concentration of power stifles innovation and creates a global dependency on closed systems. Its answer isn’t just another chatbot or copilot. Instead, Reflection AI is focused on building fully autonomous agents that can understand, write, and independently evolve complex software codebases—a significant leap beyond current-generation developer assistants.

This ambitious goal is backed by what the company calls a proprietary “frontier LLM training stack,” a framework designed to advance reinforcement learning and agent orchestration. While details are sparse, the promise has attracted a who’s who of Silicon Valley and strategic investors.

With this massive war chest, Reflection AI plans to scale its research and infrastructure, aiming for the public release of its first open-source frontier language model in 2026. It’s a bold, capital-intensive strategy that pits a relatively new startup against the most powerful technology companies in the world. But with backing from Nvidia and a clear mission to democratize frontier AI, Reflection AI is now one of the most formidable challengers in the race to build the future of intelligence.

The new funding includes capital from Eric Schmidt, Citi, and 1789 Capital, with continued support from Lightspeed, Sequoia, and Zoom founder Eric Yuan.
