A request that never gets an answer will cost money again. Per Anthropic's ClaudeDevs account, the company is resuming charges for requests its safeguards block before Claude responds, citing "some coordinated attacks on our systems in recent weeks."

The rule covers only three categories where Anthropic says false positive rates are low: biology, distillation attacks, and frontier LLM development. Distillation means training a rival model on another model's outputs, the practice Anthropic has been fighting in public.

Anthropic didn't say what a blocked request costs or how low those false positive rates actually are. The announcement says charging resumes today.

The Democratic Republic of the Congo is facing an outbreak of an unusual Ebola variant, and global health groups have brought Claude into the response. Anthropic says CEPI, WHO's Africa office and Kinshasa's INRB are among the organizations using Claude to speed up that work. The short announcement doesn't say which tasks Claude handles. It points readers to a longer feature piece on Anthropic's site.

A post on Threads claims a Liquid Glass UI revamp for Claude on iOS is "almost ready," and it moves navigation to a bottom tab bar along with other tweaks. Anthropic hasn't announced a redesign, and we found no independent confirmation of the report. The post doesn't list the other tweaks or give a release date.
