Zed AI Review (2026)

Zed is the editor built from the ground up by the original Atom team to be GPU-accelerated, multi-buffer, and Treesitter-native. Zed AI (the integrated assistant) added agent panels, inline assist, and Cascade-style multi-file edits in 2025–2026, with model choice across Claude Sonnet 4.5, GPT-5.1, and Gemini 2.5 Pro. It's the editor to pick when you care about latency above everything else — completion and chat round-trips are visibly faster than VS Code-based competitors. Live collaboration (Zed's original differentiator) means pair-programming sessions can include the AI as a third participant.
