OpenAI ships ChatGPT and Codex desktop app for Linux

OpenAI closed its last desktop gap Tuesday: a preview ChatGPT app for Linux that brings ChatGPT, ChatGPT Work, and the Codex coding agent to the operating system where much of the world's AI development already happens.

OpenAI released a ChatGPT desktop app for Linux in preview, ending the platform's years-long status as the odd one out among major desktop operating systems. The app went out worldwide Tuesday, bundling ChatGPT, ChatGPT Work, and Codex, with OpenAI saying the launch "extends ChatGPT and Codex across every major desktop operating system." Supported distributions are desktop variants of Ubuntu 24.04 and 26.04 LTS, Debian 13, and Fedora 43 and 44 — the bases for a wide range of downstream distros and flavors, which OpenAI says should be compatible too.

The launch closes a glaring gap. Linux users have always had ChatGPT in the browser, but the desktop experience — local file access, the Work agent, desktop control for Codex — stayed exclusive to macOS and Windows. In the absence of an official client, the community improvised: unofficial wrappers, Snap packages, and a GitHub project with thousands of stars that repackages OpenAI's macOS app into native Linux packages, all while OpenAI's Linux waitlist gathered signups for years.

The interesting part isn't the chat client, though — it's Codex. OpenAI's agent gained the ability to see, click, and type on a user's machine through desktop control, and that capability had never reached Linux natively. That matters because Linux is where a large share of professional AI coding actually happens, making it the developer audience OpenAI's other apps couldn't fully serve. It also puts OpenAI on more even footing with Anthropic, which shipped a Claude desktop app for Linux about a month ago with broader distro support.

The timing reads as deliberate: with Codex, ChatGPT Work, and Claude Code all native on Linux, the desktop has become the battleground for AI coding agents — and OpenAI just showed up to a fight it was losing by absence. The preview label is a caveat; feature parity with the macOS and Windows builds may lag, and rough edges are likely. But the strategic signal is unambiguous: OpenAI now treats Linux as a first-class market, not an afterthought.

What to watch: whether the preview graduates to a full release with parity, and how Anthropic defends its month-long head start.

Now that Codex runs natively on Linux, is it your desktop agent of choice — or does Claude Code stay ahead? 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
