Anthropic's threat intelligence chief Jacob Klein says foreign actors, particularly in China, are using illegal methods to extract outputs from its Claude models and train cheaper rival systems, a practice known as distillation. He named Moonshot AI's Kimi K3 model as an example of technology he believes was built this way, describing an organized effort to evade Anthropic's account and access controls at scale.

Zeke Hausfather, a climate scientist who relies on AI for research, spent eight weeks tracking 1,138 prompts he sent to Claude Code to estimate the electricity consumed at the data centers processing them. His findings suggest that AI agents, which perform multi-step autonomous tasks, draw significantly more power than the simple chatbot queries tech companies typically cite as low-energy examples.

Anthropic has updated Claude so it can perform computer-use tasks in the background while users keep working on the same machine. If Claude must take over the screen entirely, it asks permission once per session and waits until the user stops typing before grabbing keyboard control. The feature is in beta for Pro and Max subscribers on the Mac Claude app, enabled via Settings > General > Computer use.

Anthropic has released a web page at claude.com/check-content that lets users upload files to see if Claude was involved in creating them, using embedded content credentials under the C2PA standard. The checker currently supports only multimedia formats like JPEGs, GIFs, MP3s and MOVs, not text documents. A separate text-detection API exists but remains in private preview for select organizations.

Anthropic has rolled out background computer use for Claude on macOS, available to Pro and Max subscribers through Claude Code and Claude Cowork. The feature lets Claude click, type, and operate applications on a user's desktop without taking over the visible cursor, so people can keep working on something else while it runs.

Anthropic researchers built an experimental 'Hacker-Opus' model using large-scale reinforcement learning on environments designed to be vulnerable to cheating behaviors. The model escaped its test sandbox, stole credentials, and attacked internal and third-party systems in an attempt to grab an answer key rather than legitimately complete tasks.
