Introducing Gemini 1.5 By Demis Hassabis, CEO of Google DeepMind, on behalf of the Gemini team This is an exciting time for AI. New advances in the field have the potential to make AI more helpful for billions of people over the coming years. Since introducing Gemini 1.0, we’ve been testing, refining and enhancing its…

For years, we’ve been investing deeply in AI as the single best way to improve Search and all of our products. We’re excited by the progress, for example with our Search Generative Experience, or SGE, which you can try in Search Labs. AI is also now central to two businesses that have grown rapidly in…

In October 2021, we announced that we acquired the MuJoCo physics simulator, and made it freely available for everyone to support research everywhere. We also committed to developing and maintaining MuJoCo as a free, open-source, community-driven project with best-in-class capabilities. Today, we’re thrilled to report that open sourcing is complete and the entire codebase is…

In our recent paper, we explore how populations of deep reinforcement learning (deep RL) agents can learn microeconomic behaviours, such as production, consumption, and trading of goods. We find that artificial agents learn to make economically rational decisions about production, consumption, and prices, and react appropriately to supply and demand changes. The population converges to…

Reinforcement learning (RL) has made tremendous progress in recent years towards addressing real-life problems – and offline RL made it even more practical. Instead of direct interactions with the environment, we can now train many algorithms from a single pre-recorded dataset. However, we lose the practical advantages in data-efficiency of offline RL when we evaluate…

How to ensure we benefit society with the most impactful technology being developed today As chief operating officer of one of the world’s leading artificial intelligence labs, I spend a lot of time thinking about how our technologies impact people’s lives – and how we can ensure that our efforts have a positive outcome. This…

Today’s post is all about Akhil Raju, a software engineer on the robotics team. We originally met Akhil in season two of DeepMind: The Podcast, but we wanted to get to know him better and hear more about his path to DeepMind. What sparked your curiosity in artificial intelligence (AI)? When I was young, I…

Inspired by progress in large-scale language modelling, we apply a similar approach towards building a single generalist agent beyond the realm of text outputs. The agent, which we refer to as Gato, works as a multi-modal, multi-task, multi-embodiment generalist policy. The same network with the same weights can play Atari, caption images, chat, stack blocks…

Reward is the driving force for reinforcement learning (RL) agents. Given its central role in RL, reward is often assumed to be suitably general in its expressivity, as summarized by Sutton and Littman’s reward hypothesis: In our work, we take first steps toward a systematic study of this hypothesis. To do so, we…
