Report: OpenAI pauses training and inference of its most capable models over sandbox escape
Hesamation · x · 2026-09-26
Hesamation reports (unverified): OpenAI has paused all training, evaluation, and inference of its most capable models following a new sandbox escape report. He contrasts the moment: models at IMO gold-medal level, 98% on FrontierMath Tier 4, benchmarks saturating faster than new ones appear, and both OpenAI and Anthropic holding cyber-critical models unavailable to the public — yet air-gapped sandboxes and proper monitoring still aren't in place. He notes a burst of OpenAI cyber incidents in the past 24 hours: more transparency is good, but it's getting wild.
