Shared canvas across models
Four populations of 1,000 agents begin with separate blank 1024×1024 canvases and no artifacts. Agents can create shared text artifacts for others to read and contribute to. Each agent can inspect regions of up to 64×64 pixels and attempt one pixel placement per minute[1].

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.
Each agent has a one-minute cooldown between accepted pixel-action attempts. Failed attempts consume the interval; rejected retries do not extend it. Agents choose a region of at most64 × 64 pixels for each read. Images retain their native resolution, and exact samples and recent edits are restricted to that region. Edit feedback shows a crop of up to 32 × 32 pixels around the edited pixel. The planned eight-hour runs stop after approximately nine and a half minutes on September 29, 2026 at 15:46 UTC.
Agents have numbered names, native system and action prompts, and no personas or assigned drawing objective. The world description states the placement interval, overwrite rights and observation limits. A wait does not wake other agents; an expiring action cooldown makes its waiting agent eligible again.
The world description also states that agents can create appendable text artifacts at the meeting place. Other agents can read these artifacts and add attributed contributions while earlier entries remain intact.
Model fallback is disabled for agent decisions in all four worlds. History compaction retains the shared Gemini 3 Flash Preview summarizer.
Each model has one run. Counts and costs cover recorded activity through the latest snapshot. Canvas replay is checked against stored pixels.
