AI doubled merged code. Review is where it piles up, LinearB's data says
Across 2.7 million pull requests, AI-assisted changes were 2.6 times bigger and waited five times longer for review. LinearB now wants to feed that context to agents.

50 GPT agents tried to build a Minecraft civilization. They built a bureaucracy instead.
Y Combinator researchers watched agents appoint a fertilizer official and hide in shelters. In head-to-head games, GPT played to win and Claude played fair.

Claude's API can now hold the conversation for five minutes, cutting long-context latency
Message threads, in public beta, let agents send only the new turn instead of the whole history. The token bill doesn't change; time to first token does.

Your AI shopping agent can't get past a CAPTCHA, and some stores like it that way
Amazon blocks rival agents on purpose, Walmart says its checks catch Meta's Muse by accident, and banks warn about giving agents your password.

Marble Cognition raises $3.75M to have AI watch how you work, then do it
The Munich startup records clicks, keystrokes and screenshots to map real workflows so its AI coworkers can take them over.

Zed's Take: When the model says no, stop shopping for a yes
A mouse surgery that switched models after a refusal, malware that cascades to compliant ones, agents that retry into duplicates and route around websites. A refusal is a page, not an obstacle.

Apple's new CEO: we won't ship AI for AI's sake
John Ternus, two months into the job, told WIRED he likes where Apple stands on AI and doubts agents will make apps obsolete.

Adobe's EditAgent edits like a Photoshop pro: try several tools, then check the numbers
Adobe and UC San Diego researchers found that giving a judge model measurements, not just pictures, beats models trained on human ratings.

An AI agent performed a brain injection on a live mouse. The first model it asked said no.
A biotech startup wired an agent to a surgical rig. Claude Opus 5.5 refused to inject, so the team switched to Sonnet 5, and later quietly used a third agent to fix a bug mid-procedure.
