Run phaseo zed to add a Phaseo provider to Zed’s settings.json, then paste the key into Zed, which keeps provider keys in the system keychain. To skip the CLI, add the provider in Zed’s settings yourself.

​
Set up with the Phaseo CLI

The CLI creates a Phaseo CLI: Zed API Key (90-day expiry, $100 monthly spend limit) and adds an openai_compatible provider named phaseo, with API URL https://api.phaseo.app/v1 and the selected model, to Zed’s settings.json. Unrelated settings are left alone. Without --model, it uses anthropic/claude-sonnet-4.6. Setup stops if Zed already has a provider named phaseo.

​
Add the key in Zed

  1. Open the command palette and run agent: open settings.
  2. Under AI, select LLM Providers → Configure.

  1. If Phaseo appears, open it and paste the output of phaseo integrations credential zed.
To add the provider without the CLI, select Add Provider → OpenAI instead and enter the values below. Zed LLM Providers page with Add Provider Zed form for adding an OpenAI-compatible provider Fill in the API URL, model, and key before you select Save Provider.

​
Check it works

Open a new Agent thread, select the Phaseo model, and send a short request. Confirm it appears in Settings → Usage → Logs. If Zed reports an invalid key, run phaseo integrations credential zed again and replace the key in Zed.

​
Remove Phaseo

This removes the Phaseo provider from settings.json and revokes the key. If Zed still shows the old keychain entry, remove Phaseo from LLM Providers too.
