Simon Willison Shares GPT-6 Astra Pelican Comparison

Simon Willison announced on X that he received access to GPT-6 Astra. He posted a grid comparing its output against GPT-5.6 Sol, Terra, and Luna using illustrations of pelicans riding bicycles. The grid displays twelve images arranged by model. His linked page presents an SVG reasoning-effort comparison for the GPT-6 and GPT-5.6 series. The page also states pricing per million input and output tokens: Astra at ten dollars and fifty dollars, Sol at five dollars and thirty dollars, Terra at two dollars fifty cents and fifteen dollars, and Luna at one dollar and six dollars.
