Ineffable Intelligence has secured a record-breaking $1.1 billion in Seed funding at a $5.1 billion valuation, marking its first external capital raise. The company, founded by DeepMind's former RL lead David Silver, will use the funds to develop its "superlearner" AI using Reinforcement Learning. The round was co-led by Sequoia and Lightspeed, with significant participation from NVIDIA, Google, and the UK's Sovereign AI Fund.
