Zero-shot and single-turn. Models received no example image, example answer, or conversation history. A local Node.js harness sent the same prompt, recorded time and OpenRouter cost, and validated the 32×32 result.
Price is the OpenRouter-reported API cost. Time is elapsed request time.
Artificial Analysis Intelligence Index, snapshot 2026-08-22. Each score matches the exact model and thinking level tested by Artificial Analysis. No score is shown when that combination was not tested.
Output limit reached means the model or provider stopped the response before it completed all 32 pixel rows, so there was no valid image to display.
