Nvidia Partners With British Startup Ineffable Intelligence at $5.1 Billion Valuation to Build Reinforcement Learning Superlearners

Nvidia announced on May 13 a strategic engineering partnership with Ineffable Intelligence, the London-based AI startup founded by former Google DeepMind reinforcement learning chief David Silver. The two companies will co-design large-scale reinforcement learning infrastructure on Nvidia's Grace Blackwell chips and upcoming Vera Rubin platform.

Ineffable, only founded in late 2025, raised a record $1.1 billion seed round in April at a $5.1 billion valuation. The round was co-led by Sequoia Capital and Lightspeed Venture Partners, with participation from Nvidia, Google, DST Global, Index Ventures and the UK Sovereign AI Fund.

"The next frontier of AI is superlearners — systems that learn continuously from experience," Nvidia CEO Jensen Huang said. The bet signals an industry shift away from pure LLM scaling toward agents that improve through trial and error rather than static human-generated data.
