Connect Zed to TrustedRails

Zed is a fast, multiplayer code editor with a built-in AI agent. It supports OpenAI-compatible providers natively, so you can add TrustedRails in its agent settings and run the agent on open-source models; no extension needed.

Prerequisites

Section titled “Prerequisites”

Add TrustedRails as a provider

Section titled “Add TrustedRails as a provider”
  1. Open the agent settings: run agent: open settings from the Command Palette (Cmd/Ctrl + Shift + P). Under LLM Providers, click Add Provider and choose OpenAI (this means an OpenAI-compatible API).
  2. In the Add LLM Provider dialog, fill in:
    • Provider Name: TrustedRails
    • API URL: https://proxy.trustedrails.com/v1
    • API Key: your tr-prx-… key
  3. Under Models, click Add Model and enter a TrustedRails model id in Model Name, for example zai-org/GLM-5.3-Flash. It must match a TrustedRails-supported id exactly (see Supported Models). Keep the token defaults (or set them to the model's context window) and tick Supports tools so the agent can call tools; leave the other capability boxes at their defaults. Use Add Model again for any other model, e.g. MiniMaxAI/MiniMax-M2.7.
  4. Click Save Provider.

To change the provider later, edit it in your settings.json (run zed: open settings file; Zed saves the provider there), or remove it and add it again; there is no edit button in the UI.

Use it

Section titled “Use it”

Open the Agent panel, pick a TrustedRails model from the model selector, and start a conversation or let the agent edit files and run commands, all on your open-source model.

Verify

Section titled “Verify”

In the Agent panel, with a TrustedRails model selected, send any message. A reply confirms the connection.

Troubleshooting

Section titled “Troubleshooting”
  • Provider or models don't appear: re-open agent: open settings and confirm the provider saved with API URL exactly https://proxy.trustedrails.com/v1.
  • 401 / invalid API key: wrong or paused key, or it wasn't saved. Re-enter it, or create a fresh one from Create a TrustedRails API Key.
  • Model not found / unsupported: the Model Name must match a model TrustedRails serves exactly (see Supported Models).
