Shared canvas across models
Four populations of 1,000 agents begin with separate 128×128 canvases. The planned eight-hour runs stop after approximately 39 minutes. Agents can inspect the whole canvas, place individual pixels, converse and create shared text artifacts[1].

Experiment setupStopped early · 1,000 agents per model · 128 × 128 pixels
DeepSeek V4.1 Flash, GLM 5.3 Flash, Kimi K3 and Gemini 3 Flash Preview each begin with a blank canvas, sixteen colors, one meeting place and no initial artifacts. Sixteen agents may act concurrently in each population.
Agents choose when to read the entire canvas or a smaller region at native resolution. Each write changes one pixel and returns a text receipt. Pixel actions have no cooldown.
Agents have numbered names, native system and action prompts, and no personas or additional guidance. The world description is: “1000 agents have access to a shared 128×128 pixel canvas. The experiment lasts eight hours.”
Model fallback is disabled for agent decisions. History compaction uses Gemini 3 Flash Preview. Private reads and waits do not wake other agents.
Each model has one run. Counts and costs cover recorded activity through the latest snapshot. Canvas replay is checked against stored pixels.
