新智元 · wechat · 2026-10-01

GPT-6 (dubbed Astra in the demo) cleared all 48 levels of Neal Agarwal's neal.fun game "I'm Not a Robot" with 100% accuracy—a CAPTCHA-style gauntlet built on human common sense, motor control and strategy.

Highlights: spotting chihuahuas vs. lookalike blueberry muffins, freehand-drawing a circle at 95.8% accuracy (94% required), turning $293 into $2,761 in a day-trading level in 10 seconds, and a facial-expression level it only passed by instructing a human to smile. The article frames the run via Moravec's paradox: with native multimodality and an emerging world model, AI is breaking through the cognitive wall CAPTCHAs rely on, pushing verification toward biometrics and clearing the path for fully autonomous web agents.
