GitHub Copilot CLI is GitHub’s coding agent for the terminal. It supports custom model providers through environment variables, so it runs on any model in the Opper catalog — and with a custom provider configured, it needs no Copilot plan and no GitHub sign-in.

​
Setup

COPILOT_PROVIDER_TYPE also accepts anthropic for the Anthropic Messages format — both work against Opper’s gateway, which serves each surface from the same base URL. Run copilot help providers for the full reference.
GitHub documents COPILOT_PROVIDER_BASE_URL and COPILOT_MODEL as the required pair; the type and key variables are what point it at Opper specifically. GitHub’s own BYOK docs don’t spell out whether a Copilot plan stays mandatory, so if you’re prompted to sign in on a managed or enterprise-provisioned install, that’s your org’s policy rather than the gateway.

​
Choosing a model

Set COPILOT_MODEL to any model ID from the catalog. Copilot CLI needs tool calling and streaming — pick a model the catalog marks with the tools capability.

​
Troubleshooting

The provider variables have to be set before copilot starts, in the same shell. Check COPILOT_PROVIDER_BASE_URL and COPILOT_MODEL first — GitHub treats those two as required — then confirm COPILOT_PROVIDER_TYPE and COPILOT_PROVIDER_API_KEY are exported too.
Copy the model ID exactly from the catalog, including the provider prefix.
The model needs tool-calling support. Check the model is marked with the tools capability in the catalog and switch if not.
