This is not a complete picture. I use Zed daily and I have the AI features enabled, but I never use the built in agent in Zed. I reach for an agent in a separate terminal session.
More people are probably using stuff like Claude Code, Codex etc from the CLI or desktop apps, meaning they’re actually using more AI and skipping Zed altogether
Anecdotally: I disabled Zed’s AI features, but I use LLMs more extensively than ever outside of my IDE. So the numbers may not paint a clear story here.
