Anthropic's Claude sees 'elevated errors' as it tops Apple's free apps after Pentagon clash

Anthropic's Claude artificial intelligence models had "elevated errors" on Monday, as the app held its spot as the most popular free app on Apple's App Store.

Claude's status website showed "degraded performance" on Claude Opus 4.6, its latest model released last month. In an update at 9:42 a.m. ET, the site stated that the issue was identified and a fix was in the works.

The AI chat app surged in popularity after fallout with the Defense Department over restrictions for the government agency's use of Anthropic's technology.

On Friday, President Donald Trump ordered every U.S. government agency to "immediately cease" using Anthropic's technology. Defense Secretary Pete Hegseth announced on X shortly after that the Pentagon would be labeling the company a "supply-chain risk to national security."
