Connect T3 Code with Zeldoc.ai

T3 Code is an open source control surface for coding agents. It runs as a desktop app on macOS, Windows, and Linux, as a web app, and as mobile apps, and it drives agents such as OpenCode, Codex, and Claude Code that are installed on your machine. T3 Code doesn't call models itself: for OpenCode it starts an OpenCode server through the OpenCode SDK, so Zeldoc.ai is available in T3 Code as soon as it's connected in OpenCode.

Prerequisites​

Enable OpenCode in T3 Code​

  1. Confirm that OpenCode can see Zeldoc.ai from a terminal:

    opencode models

    zeldoc/zdev should appear in the list. If it doesn't, go back to Connect OpenCode with Zeldoc.ai — T3 Code can only offer models that OpenCode already knows about.

  2. Open T3 Code and go to Settings → Providers.

  3. Select the environment you're working in and enable the OpenCode provider.

  4. Start a new thread and pick ZDev from the model picker.

Model missing from the picker?

If you connected Zeldoc.ai after enabling the provider, choose Refresh provider status in Settings → Providers. T3 Code reloads the models, commands, and skills it gets from OpenCode.

Your OpenCode config still applies​

Because T3 Code runs a regular OpenCode server, everything in your opencode.jsonc is honoured — including the provider block, context limits, and the recommended privacy config that disables sharing and the default OpenCode provider.

If you point T3 Code at an OpenCode server on another machine by setting a Server URL in the provider settings, Zeldoc.ai has to be connected in OpenCode on that machine. T3 Code doesn't forward your local API key or environment variables to a remote server.
