After launching on macOS, Anthropic's AI assistant Cowork is now available for Windows users. The Windows version includes the full feature set from the macOS release: file access, multi-step task execution, plugins, and MCP connectors for integrating external services. Users can also set up global and folder-specific instructions that Claude follows in every session.
Cowork on Windows is currently in Research Preview, an early testing phase. The feature is available to all paying Claude subscribers at claude.com/cowork.
Anyone who installs the system and gives it access to their files—especially sensitive or private data—should be aware of the cybersecurity risks. Generative AI can be exploited through adversarial prompts (prompt injections), among other attack vectors. This is exactly what happened to Cowork shortly after its launch.
Half of xAI's co-founders have now left Elon Musk's AI startup
Jimmy Ba is the latest co-founder to leave xAI, and like the five who left before him, he’s full of praise for the company and predicts massive AI breakthroughs ahead. Yet somehow, half of xAI’s twelve founding members have still walked out the door.
OpenAI has upgraded Deep Research in ChatGPT. The feature now runs on the new GPT-5.2 model, as OpenAI announced on X. A key addition is that users can connect apps to ChatGPT and—potentially very useful—search specific websites. The search progress can also be tracked in real time, interrupted with questions, or supplemented with new sources. Results can now be displayed as full-screen reports.
That said, even web searches don't protect against generative AI errors, and the longer the generated text, the higher the risk of mistakes. In everyday use, targeted search queries with capable reasoning models are often more reliable. Web search significantly reduces hallucination rates overall, but doesn't eliminate them.
Chinese robotaxi operator Pony AI and Toyota have kicked off commercial production of a self-driving electric car. The first of 1,000 fully electric, autonomous Toyota bZ4X compact SUVs has rolled off the assembly line at a joint venture plant run by Toyota and the Guangzhou Automobile Group. The vehicles are meant to help Pony AI hit its goal of expanding its robotaxi fleet to more than 3,000 cars by the end of the year. The bZ4X is one of three models Pony AI is deploying with its latest autonomous driving software across major Chinese cities.
The vehicles run on Pony AI's autonomous driving system, rated at SAE Level 4. That means the car drives itself completely within designated areas - no human needs to sit behind the wheel, hold the steering wheel, or watch the road. There are still limitations, though, such as restrictions on operating zones or weather conditions.
Even though the technology enables driverless operation, human support is still part of the equation. Right now, one person oversees roughly 30 vehicles and can step in if something goes wrong.
Pony AI competes with other Chinese robotaxi companies like Baidu and WeRide.
OpenAI is rolling out ads in ChatGPT for users in the United States. The test targets logged-in adult users on the free and "Go" tiers. Plus, Pro, Business, Enterprise, and Education plans remain ad-free. Free-tier users can opt out of advertising, but doing so reduces their daily message allowance.
OpenAI says the decision comes down to high infrastructure costs. The company stresses that ads don't influence ChatGPT's responses, and conversations stay private. Which ad a user sees depends on the conversation topic, previous chats, and interactions.
Users under 18 won't see any ads, and ads won't appear around sensitive topics like health or politics. Users can hide individual ads, delete their ad data, and adjust personalization settings. Advertisers get aggregated performance statistics but have no access to chat logs or personal data, OpenAI says.
What will always remain true: ChatGPT’s answers remain independent and unbiased, conversations stay private, and people keep meaningful control over their experience.
OpenAI CEO Sam Altman told employees in an internal Slack message that ChatGPT is once again growing by more than ten percent per month,CNBC reports. The last official number was 800 million weekly users in January 2026.
Altman also said an updated chat model for ChatGPT is set to ship this week. It could be the chat variant of GPT 5.3, which OpenAI released last week as the coding-focused version Codex. The model scores particularly well on agent coding benchmarks and is 25 percent faster, according to OpenAI.
