ARC-AGI-3 Stumps Every AI Model, Reddit’s Bot Crackdown, Google Shrinks AI Memory

Today we’re covering the biggest AI stories of March 26th, 2026. The ARC Prize Foundation dropped ARC-AGI-3, a new reasoning benchmark where humans score 100% on the first try but every frontier AI model scores below 1% — with Google’s Gemini Pro leading the pack at just 0.37%. Reddit CEO Steve Huffman announced a plan to label and verify bots across the platform, letting communities self-police AI-generated content without mass ID checks, as automated traffic is on pace to surpass human traffic by 2027. Plus, Google Research unveiled TurboQuant, an algorithm that compresses AI model memory over 6x with zero accuracy loss and up to 8x speed gains — rattling memory stocks in the process — and a community workflow from a new mom on maternity leave who built a custom baby tracking dashboard with Claude Code that emails her daily coaching summaries.
