- WIRED found dormant face-recognition code called NameTag inside Meta's AI companion app, installed on more than 50 million phones since January 2026.
- The system used three AI models to detect faces, crop them, and encode biometric signatures on-device, with unrecognised faces indexed and stored locally.
- Meta stripped nearly all the code within a day of WIRED's report, said the feature does not exist, and called the reporting 'incredibly misleading.'

- Anthropic says shared links are 'not guessable or discoverable unless people choose to share them themselves,' but Google is doing the discovering.

Not a typo! Lotta caveats here it seems, but even the 62.7 score is an insane leap forward. ARC-AGI-3 is uniquely difficult. arcprize.org/blog/astra

The telltale sign of a Claude dashboard. In the future designers will be like "I want to evoke the early days of AI. Like 2026 Claude dashboard shit"
One idea that has crystallized for me — using AI to help you make custom tools to express your ideas is super powerful. AI is not making the end product, but lets you build a super-custom magical tool for just the thing you want to build.
