SignalBetaWhat the people building AI said today8 October 2026

Microsoft moved Copilot closer to acting across a user’s PC, as Replit highlighted the security risks of desktop agents. OpenAI focused on interfaces generated for individual questions, while Anthropic cut the price of its smallest Claude model.

Copilot reaches across Windows

Microsoft says Copilot will, with permission, use PC context, take actions across Windows and call local models under its Hybrid Intelligence approach. Replit CEO Amjad Masad says desktop AI apps can expose users to supply-chain attacks and severe agent errors, and says Replit is focusing on security and reliability.
