The Rust-built code editor with first-class Anthropic support — fast enough that you actually notice when the API isn't.
Zed's Assistant panel sends full file context plus selection on every prompt. The new Agent mode runs multi-turn edits across files, similar to Cline / Cascade. Heavy users on BYOK Anthropic see $100-200/month — through us, $20-40.

Default Assistant + Agent model
Quick inline edits, cheap completions
Multi-file refactors, hardest reasoning
Yes. Zed's settings.json accepts language_models.anthropic.api_url. Point it at https://claudeapi.cheap/api/proxy, paste the sk-cc- key via the command palette, and the Assistant + Agent both route through us.
Zed also supports language_models.openai.api_url. Set it to https://claudeapi.cheap/api/proxy/v1 to route GPT-5 through our /v1/chat/completions endpoint.
Zed's Predict (formerly Copilot-style suggestions) is a separate hosted product on Zed's side and is NOT affected. Only Assistant chat + Agent mode route through your custom api_url.
