UX

GitHub published a blog post arguing that canvas-style interfaces—rather than chat logs—are better suited for tracking and steering agentic coding workflows in Copilot. The post frames canvases as a way to keep long-running agent work visible and controllable without re-running expensive steps.

OpenAI added a long-press gesture to ChatGPT's mobile app that lets users select intelligence levels (Instant, Thinking, Extended) before sending a message. The update also includes a table of contents feature for conversations with 5+ responses and improvements to the GPT-5.5 Instant model.
