An export-control order meant to block foreign users forced a total shutdown because Anthropic couldn't filter by nationality in real time.
Why now: Covered in the July 10 briefing alongside OpenAI's GPT-5.6 rollout the day before.
The Commerce Department ordered Anthropic to disable Fable 5 and Mythos 5 for every customer, then reversed the order, per Last Week in AI. Anyone running production code against either model lost API access without warning, then got it back the same way. That's a new kind of outage: not a bug, not a rate limit, a government order.
The order targeted foreign nationals only. Anthropic had no way to filter users by nationality in real time, so every customer lost access instead. Access returned when Commerce reversed the order.
Engadget frames OpenAI's July 9 GPT-5.6 release as the company getting permission to ship, though that's one outlet's characterization, not a confirmed process.
Commerce showed it can pull a frontier model offline for every customer on export-control authority alone, then hand it back. That capability doesn't disappear when the news cycle does. Watch whether Anthropic ships real-time nationality filtering. If it does, this is a one-time story. If it doesn't, expect a repeat.
