A Generalist Agent vs Kalos.art

Gato is the generalist agent DeepMind introduced in its May 2022 research post "A Generalist Agent." One transformer policy with shared weights handles chat, image captioning, Atari games, and real robot arm block stacking from the same model. The post describes it as a multi-modal, multi-task, multi-embodiment policy that picks whether to emit text, joint torques, button presses, or other tokens based on context.

Most tools in this space train a separate model per task domain. Gato instead serializes every modality and environment into a flat token sequence and runs it through a transformer shaped like a large language model. That means one pretrained checkpoint moves between dialogue, vision, and control without swapping architectures.

During training, data from simulated and real environments mixes with natural language and image datasets, with loss masked so Gato predicts only action and text targets. At deployment, a prompt tokenizes first, each new observation appends to the sequence, and the model samples an action vector one token at a time inside a 1024-token context window. The blog includes domain-grouped charts of tasks where the pretrained model clears expert score thresholds.

lib.KALOS.art is a browsable style reference library for AI image generation. It catalogs artist names and art genres organized for Midjourney v5.2, Midjourney v4, SDXL, Stable Diffusion 2.1, and Stable Diffusion 1.5. Each model gets its own library slice so you can see which prompts and references work on the engine you actually run.

Most prompt libraries dump the same artist list for every model. lib.KALOS.art sizes each library to what that model recognizes, from 767 artists on SD 2.1 up to 1,340 on MJ v5.2 and SDXL, with 292 genre and medium categories alongside the artist index. Every artist and genre entry ships with 8 to 11 themed example galleries so you compare outcomes before copying a prompt.

AI art hobbyists and working prompt engineers use it to look up a style, copy a tuned prompt through the built-in copier, and save favorites once they log in. It sits beside the broader Kalos.art marketplace but stays focused on reference browsing rather than selling artwork.
