Nvidia is pushing into the PC market with its own chips as the main processor. The first Windows computers from Dell and Microsoft's Surface line are set to be unveiled next week at Computex and Build. Microsoft is also planning new software likely based on the OpenClaw framework that lets AI agents handle tasks locally on Windows PCs, a second shot after the Copilot+ PC concept largely flopped.

OpenAI is updating GPT-5.5 Instant for more natural responses and dropping the Canvas feature from its latest models. Writing and coding tasks will run directly in the chat instead. The company is also retiring the older o3 and GPT-4.5 models from ChatGPT, with both shutting down by August 2026 at the latest.

OpenAI's Codex app now runs on Windows 11 with "Computer Use": the AI can independently control programs, test apps, and hunt for bugs. When no one's at the PC, the ChatGPT mobile app lets users start and monitor tasks remotely from their phone.

Attackers are exploiting the chat-sharing features in ChatGPT and Claude to spread malware through shared conversations. The chats mimic error messages or install guides and slip past security tools undetected because they're hosted on trusted domains.

An unnamed company allegedly blew half a billion dollars on Claude licenses in a single month because nobody set usage limits. Cases like this show that without real AI expertise in model selection and context engineering, productivity promises just turn into runaway costs.
