“The game is over!” he tweeted, suggesting that there is now a clear path from Gato to artificial general intelligence, or AGI, a vague concept of human- or superhuman-level AI. One of DeepMind’s top researchers and a coauthor of the Gato paper, Nando de Freitas, couldn’t contain his excitement. While Gato is undeniably fascinating, some researchers have gotten a bit carried away in the week since its release. The tokenization, network design, loss function, and deployment of Gato are described in the subsections below. Sampled tokens are constructed into dialogue responses, captions, button presses, and other actions based on the context during deployment. Gato can be trained and sampled from this representation in the same way that a normal large-scale language model can.

It serializes all data into a flat series of tokens to facilitate the analysis of this multimodal input. Gato’s main design principle is to train on as many different types of data as possible, including photos, text, proprioception, joint torques, button presses, and other discrete and continuous observations and activities. Within its 1024-token context window, the model is always aware of all previous observations and actions.
The action is decoded and delivered to the environment, producing a new observation, when all tokens composing the action vector have been tested (as stated by the environment’s action specification). It is accomplished by sampling the tokenized weights from the first step into autoregressive action vectors one token at a time.
It can interact with languages, and images, play games and interact with mechanical objects when treated as weights. Gato operates by normalizing and modulating all the inputs and data streams from various jobs into flat token sequences. It is a generalist policy that is multimodal, multi-task, and multi-embodiment. Gato can do over 600 various things, including play video games, caption photos, and move real-world robotic arms. Gato, as the agent is known, is the generalist AI of DeepMind that can execute a wide range of jobs that humans can, without specializing in a single skill. It’s time to ask if Gato has a better chance is being an AGI than AlphaZero.
