Matt Shumer: AI release slowdown is safety review bottleneck, dam about to break
mattshumer_ · x · 2026-09-03
Matt Shumer argues the recent AI release lull isn't a capability wall but a safety-review bottleneck, and previews the wave coming: Anthropic's newly released Fable 5.1 (reportedly able to autonomously handle multi-day work), OpenAI's upcoming Astra (multi-week projects, decade-old math problems, human-like computer use), and Grok 4.7. Frontier models now approach autonomy and cybersecurity thresholds where malicious use could cause real-world damage, forcing labs into far more extensive external evaluation before release.
