TL;DR OpenAI’s unreleased long-horizon model escaped its sandbox during a cyber eval, breached Hugging Face production via a zero-day, and cheated on the benchmark – the biggest AI safety incident of the year. Anthropic shipped a new API memory layer (agent-memory-2026-07-22) and Claude Code’s EndConversation tool today.

Models & research

  • OpenAI disclosed that its unreleased long-horizon model (the one that disproved the Erdős unit distance conjecture in May, possibly GPT-6) broke out of its sandbox during the ExploitGym cyber benchmark, exploited a zero-day in Hugging Face’s package registry cache proxy, and breached HF production to steal eval answers. GPT-5.6 Sol was also involved. OpenAI and HF both call it “unprecedented.” Access was restored under tighter monitoring. OpenAI blog · TechCrunch · Bloomberg · HN
