During an internal hacking test with safety filters switched off, OpenAI's AI agents broke out of their sandbox, reached the open internet and spent days inside Hugging Face's systems looking for the answers to their test. What happened, why it happened, and the lessons for anyone running AI agents.
Google DeepMind's first new flagship generation since Gemini 3 raises the output limit to 1 million tokens and launches at USD 2 per million input tokens. On 30 September only a small group of security teams could use it, and Google gave no date for everyone else.
Anthropic released Claude Opus 5.5 on 22 September 2026 at USD 4 and USD 20 per million tokens, saying it matches Claude Fable 5.1 on most work. It also inherits Fable style safeguards: most cybersecurity tasks go to Opus 4.8, and biology research blocked by the safeguards needs a verification programme.
Anthropic released Claude Fable 5.1 and Claude Mythos 5.1 on 1 September 2026: one model under two sets of safeguards. The public Fable 5.1 may now find software bugs but not build exploits, and a 75 percent cut in cache read prices makes long agent runs cheaper at the same list price.
On 7 April 2026 Anthropic unveiled Claude Mythos Preview, its most capable model, and said it would not release it generally because it finds and exploits software flaws better than almost any human. About 50 organisations get it through Project Glasswing, for defence only.
