GPT-6 Beats All 48 Levels of Neal.fun's 'I'm Not a Robot' Game as CAPTCHAs Crumble

APPSO · wechat · 2026-09-08

Neal Agarwal's 'I'm Not a Robot' browser game on neal.fun has 48 increasingly absurd levels (find Wally, draw a perfect circle, break up with your 'girlfriend'), and GPT-6 has now cleared them all — a vivid sign that visual CAPTCHAs are losing the arms race.

The data: A 2023 USENIX Security study found bots solve mainstream CAPTCHAs at 85–100% accuracy, beating humans' 50–85%; a 2024 ETH Zurich PhD project showed Google's checkbox is trivially defeated by targeted models.
A short history: CMU's warped-text Gimpy (2000, used by Yahoo) was 30% cracked within two years; Google's reCAPTCHA checkbox (2014) was bypassed at 70% accuracy by 2016.
The pivot: The industry is abandoning challenges for invisible scoring — Cloudflare Turnstile, reCAPTCHA v3's 0–1 human-probability score — and Wikipedia switched to behavior-based hCaptcha this year, challenging only 0.1% of users visually.
Context: Cloudflare estimates bot traffic rose from 30% to 60% of the web in a year, and will block mixed-purpose AI crawlers on ad-supported pages by default from Sep 15, 2026.
The deeper problem: AI agents booking tickets or research on your behalf are technically bots with legitimate intent; verifying humanity doesn't verify intent. Product design needs revocable authorization and anomaly cutoffs instead. Google is experimenting with camera-based gesture CAPTCHAs, raising new privacy and false-positive concerns.

GPT-6 also scores 92.7% on ScreenSpot-Pro (tool-free), vs 76.9% for GPT-5.6 Sol — moving from 'knowing which element to click' to actually locating and operating it.
