In this video, we take the new Claude Code Desktop App for a spin with Anthropic's brand new flagship coding model, Opus 4.7. Instead of looking at benchmarks, we push Opus 4.7 to the limit with a one-shot prompt to build a full infinite canvas app (an Excalidraw / Eraser alternative) from scratch. You'll see the complete developer experience of the new Claude Code Desktop app, including parallel agent sessions, the planning pane, bypass permissions mode, the embedded browser preview, file diff reviews, and how Opus 4.7 handles complex agentic coding tasks with the new extra-high reasoning effort.
