Use the Phaseo CLI to add the provider and model to Zed, then save the key in Zed’s keychain. To skip the CLI, enter the same provider values manually.

​
Set up with the Phaseo CLI

The CLI adds provider ID phaseo, API URL https://api.phaseo.app/v1, and the selected model to Zed’s settings.json without changing unrelated settings.

​
Finish setup in Zed

Zed stores provider keys in the system keychain, so this is the one remaining UI step.
  1. Open the command palette and run agent: open settings.
  2. Under AI, select LLM Providers → Configure.

  1. If Phaseo already appears, open it and paste the dedicated key. Otherwise select Add Provider → OpenAI.

​
Verify

Open a new Agent thread, select the Phaseo model, and send a short request. If Zed reports an invalid key, run phaseo integrations credential zed again and replace the key stored in Zed.

​
Remove

The CLI removes the Phaseo provider from settings.json and revokes its dedicated key. If Zed still shows the old keychain entry, remove Phaseo from LLM Providers as well.
