Opencode Manual Setup

Make sure you have completed the environment check before continuing with the steps below.

Opencode is an open-source terminal AI coding assistant. The following shows how to replace its Anthropic provider address with GETMODEL.

1. Install Opencode

You first need Node.js ready (see environment check), then install it globally:

npm install -g opencode-ai

2. Open the config directory

Opencode uses two directories (~ represents your user home directory, which on Windows is C:\Users\YourUsername):

File	Purpose
`~/.config/opencode/opencode.json`	Provider config: base URL, models, etc.
`~/.local/share/opencode/auth.json`	Stores your API Key

Press Win + R and enter each of the two lines below, pressing Enter, to open the corresponding directory:

%userprofile%\.config\opencode

%userprofile%\.local\share\opencode

In the terminal:

open ~/.config/opencode        # macOS
xdg-open ~/.config/opencode    # Linux

open ~/.local/share/opencode        # macOS
xdg-open ~/.local/share/opencode    # Linux

If the directories or files do not exist, create them manually.

3. Configure the provider address

Edit (or create) ~/.config/opencode/opencode.json and replace the built-in anthropic address with GETMODEL:

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "anthropic": {
      "options": {
        "baseURL": "https://getmodel.ai"
      }
    }
  }
}

About the base URL: This document uses https://getmodel.ai as an example. Please rely on the actual address shown on the Console "API Info" page.

4. Configure the key

Edit (or create) ~/.local/share/opencode/auth.json and write in your API token. Configuring just the anthropic entry is enough:

{
  "anthropic": {
    "type": "api",
    "key": "你的-API-令牌"
  }
}

Replace "你的-API-令牌" with the string you generated on the Create Token page.

When creating a key in the Console, remember to select a Claude-related group (such as "claude exclusive").

5. Verify

Open a terminal, run opencode, then enter:

/models

Pick any model under anthropic from the list, and you are ready to go.
