OpenCode

The official OpenCode docs provide the full reference. This page covers only the key steps to connect it to Global AI.
1

Install OpenCode

Install with npm:
Install OpenCode
2

Set the provider base URL

Edit ~/.config/opencode/opencode.json (create it if missing):
~/.config/opencode/opencode.json
~ is your home directory. On Windows this is C:\Users\<your username>.
3

Set the API key

Edit ~/.local/share/opencode/auth.json and replace anthropic.key with your sk- key. We recommend creating a key in the claude code group at /keys:
~/.local/share/opencode/auth.json
4

Choose a model and start

Open a terminal and run opencode. Type /models, pick an Anthropic model such as claude-sonnet-4-5, and start chatting.

​
UI configuration

If you prefer not to edit files by hand, open OpenCode’s graphical settings, switch the provider to Anthropic, set Base URL to https://globalai.vip/v1, and set API Key to your token. Return to the main screen and pick your target model from the model selector.

​
Troubleshooting

Check that opencode.json is at the correct path and that auth.json has a valid anthropic.key. Restart OpenCode after changes.
