Ineffable Intelligence adds six cofounders from DeepMind, InstaDeep

3 Key Points

  1. What happened

    Ineffable Intelligence, the London AI startup valued at $5 billion, has hired six high-profile "cofounders." Four are ex-Google DeepMind colleagues of founder David Silver, including three from the AlphaStar project.

  2. Why it matters

    The hiring follows a $1.1 billion seed round in April, the largest in Europe. It adds to a wave of researchers leaving Google DeepMind, reinforcing a perception the company is struggling.

  3. What to watch

    The new team includes reinforcement learning specialist Junhyuk Oh, suggesting Ineffable will pursue automated AI research. The startup's mission hinges on whether it can achieve superintelligence through reinforcement learning.

WHO IT HITSAI researchers and engineers considering roles at frontier labs are affected, as Ineffable's high-profile hires signal a competitive talent market. Investors tracking the 'neolabs' wave, including firms like Sequoia and Lightspeed, will watch whether this team delivers on its superintelligence mission.

Context & Analysis

Ineffable Intelligence's rapid assembly of a high-profile team is a direct challenge to Google DeepMind's dominance in AI research. Four of the six new hires are Silver's former colleagues, and three worked on AlphaStar, a breakthrough that showcased DeepMind's ability to build AI that beats humans at complex games. This influx of talent is part of a broader trend of researchers leaving DeepMind and other older labs to join 'neolabs.'

Ineffable's stated mission is to achieve superintelligence through reinforcement learning, the technique Silver is known for. The hiring of Junhyuk Oh, who was the reinforcement learning lead on AlphaStar and has explored automating AI research, suggests a focus on 'recursive self-improvement.' Similarly, Wojciech Czarnecki's background in multi-agent systems will shape their science team.

The stakes for Ineffable are high, now that it has a full founding team and a $5 billion valuation. The success of this endeavor hinges on whether this specific group of experts can use reinforcement learning to achieve more than incremental progress. The company's ability to live up to the 'superintelligence' promise, backed by a historic seed round, will likely be judged by its measurable research milestones in the coming years.
