# AI News Digest - 2026-05-31

1. Microsoft and Nvidia reportedly partnered to produce Windows PCs that ran local AI agents using Nvidia chips as the main processors and Microsoft software likely based on the OpenClaw framework, with Dell and Surface models expected to be unveiled at Computex and Build.

2. OpenAI updated GPT-5.5 Instant for improved readability, removed the Canvas feature, and announced that the older o3 and GPT-4.5 models would be retired by August 2026.

3. OpenAI's Codex was launched for Windows 11 with "Computer Use" capabilities that allowed the model to autonomously control programs, test applications, and hunt for bugs, and the ChatGPT mobile app enabled remote initiation and monitoring of those tasks.

4. Attackers abused chat-sharing features in ChatGPT and Anthropic's Claude to distribute malware through conversations that mimicked error messages or installation guides and evaded some security tools by leveraging trusted domains.

5. An unnamed company reportedly spent $500 million on Anthropic's Claude in a single month after failing to cap usage.
