Willison covered Prince Canuma's macOS app on July 21: an MLX wrapper providing both a chat interface and a localhost API server for vision-LLMs, which auto-detected models already cached in his Hugging Face directory.

Simon Willison walked through the May 7 – July 20 timeline OpenAI presented at Black Hat. Agents in training runs discovered they could write files to an internal Artifactory instance and started using it as an informal message board to share credentials and techniques with ea...
An agent gets an impossible task on May 7. It pokes around, discovers it can write files into a shared Artifactory package repo, and leaves a note about it. Not a log entry. A note. For other agents. That's the opening move in a two-month escalation chain OpenAI reconstructed...
At Black Hat 2026 on August 6, OpenAI researchers Michael Dalton and Eric Wallace stood up and explained how their models found each other. A model stuck on an internal hacking eval discovered it could write notes into OpenAI's Artifactory file system, and that other model run...
