GitHub Copilot App
Copilot's agent sessions are limited to the small, curated model list GitHub ships in the app. Add Tempr Gateway as a BYOK provider and those same agent sessions can use any model on your gateway allowlist — well beyond whatever GitHub has decided to enable that month.
GitHub controls which models appear in Copilot's picker by default, and rolls new ones out on its own schedule. A Tempr-backed provider entry puts every model you've configured — including ones Copilot hasn't added yet, or never will — directly in that same picker.
BYOK covers the app's model-powered agent sessions only. Inline code completions in your editor still use Copilot's own service. Your organization needs the "Enable custom models (BYOK)" admin policy turned on, and a recent version of the Copilot app.

Add Tempr as a provider
In the Copilot app, go to Settings → Model Providers → Add provider, choose OpenAI-compatible, set the base URL to
