Claude Cowork arrives in Chrome with skills and plugins

Anthropic's agentic workspace just got a browser home: the Chrome extension that used to read pages for you can now run a full Cowork session in its side panel, skills and plugins included.

Anthropic's Cowork agent now runs inside the Chrome extension's side panel, bringing skills, plugins, and connectors into the browser for the first time. Until now, Claude in Chrome could read the page you were on, click, type, and fill forms — fine for research, but the work stopped at the tab. With this update, a full Cowork session lives in the panel: Claude handles the research on the page, and Cowork turns it into finished deliverables — Excel files, PowerPoint decks, reports — with no extra setup. Anthropic's suggested workflows include pulling metrics from analytics dashboards, organizing Google Drive, and logging sales calls into Salesforce. Sessions are tied to your account rather than your device, so a task started in the browser follows you to the desktop app, and the update is live now for all paid plans through the Chrome Web Store.

The move matters for two reasons. First, the skills-and-plugins ecosystem Anthropic has been building around Cowork is no longer desktop-only — the same extensions that power the agent on your machine now work wherever you open Chrome, which is exactly how a productivity agent wins default status. Second, it parks a genuinely capable agent inside the page at a moment when browser-based agents are the industry's live battleground. Anthropic is keeping the guardrails visible: Claude asks for confirmation before any purchase, and the company still warns about hidden instructions on websites — the prompt-injection problem that makes every page a potential attack surface. Its advice: don't point it at banking or health data. That caveat is the honest acknowledgment that a browser agent operates in hostile territory, and it's the reason this ships as a workspace tool with training wheels rather than a free-roaming web agent.

Cowork in Chrome is less a new product than a statement of where Anthropic thinks agent work happens: on the page, next to the actual work, with the safety rails drawn in.

What to watch: whether skills built for the desktop Cowork transfer to browser sessions unchanged — and how the majors' browser-agent bets converge from here.

Would you let an agent confirm purchases on your behalf in the browser, or is that one click too many? Tell us in the comments.

Akhetonics says its all-optical CPU reaches a customer in 2026

Light-based computing keeps promising more than it delivers — but one Munich startup has just put a date on its bet, and the interview laying it out is doing the rounds on Hacker News this week. Akhetonics says it will deploy its first commercial machine with a major customer by the end of 2026, with several more planned for 2027. The company, founded by Michael Kissner and Leonardo Del Bino, is building a computer where data enters as light, is switched as light, and circulates through memory

The Week in AI — October 5–11, 2026

Every big claim this week turned out to rest on fine print more interesting than the headline: revenue only the company reporting it can define, safety tests sandboxed while the product keeps the web, and a Pentagon phase-out nobody would confirm until reporters kept asking. The week's top 5 1. OpenAI's revenue was $20 billion below the numbers everyone quoted — and the gap was definitional. The Financial Times reported Thursday that OpenAI's annualized revenue runs roughly $20 billion unde

Drone strike shuts a third Yandex data center, taking YandexGPT offline

Russia's largest tech company is learning what the AI era's infrastructure war looks like from the receiving end — three data centers in four days, and with them much of the cloud layer Russian businesses run on. A Ukrainian drone strike knocked out Yandex's data center in Vladimir early Sunday morning, the third of the company's facilities hit since October 8. The site — reported at roughly 50 MW and designed for about 2,880 server racks — stopped operating completely after the attack, Yandex

Agent teams cost up to 5x more, barely score higher

The multi-agent hype train hit a benchmark this weekend — and the grid and the trucking regulators had quiet weeks of their own. Vals AI put agent teams head-to-head with single agents on its Vibe Code Bench, and the teams cost between 1.8 and 5.1 times more for almost no extra quality. The evals company ran GPT-6 Sol and Claude Opus 5.5 solo and in teams across 50 apps at two reasoning efforts; out of four comparisons, only one was statistically significant — Sol at medium effort, where the t
