Open AI Endpoint BYOK Offline

[configmanCooper]

EDIT: IT Appears that the GUI copilot doesnt support offline mode that the github copilot cli does, there is no way to bypass github authnetication. Can this be changed?

I have an open AI endpoint in a closed environment, no internet access
Desktop app wont let move forward without signing into github

How do I set this up?

In github cli it appears you do this:

$env:COPILOT_OFFLINE = "true" # no GitHub, no telemetry, no web/GitHub MCP, no auto-update
$env:COPILOT_PROVIDER_TYPE = "azure" # MUST be "azure" for AOAI (not "openai")
$env:COPILOT_PROVIDER_BASE_URL = "https://.openai.azure.us" # HOST ONLY — SDK builds the path
$env:COPILOT_PROVIDER_API_KEY = "" # or COPILOT_PROVIDER_BEARER_TOKEN= (takes precedence)
$env:COPILOT_PROVIDER_MODEL_ID = "gpt-4o" # well-known base → gives correct tool support/token limits
$env:COPILOT_PROVIDER_WIRE_MODEL= "" # your Azure deployment name

GPT-5 series only: $env:COPILOT_PROVIDER_WIRE_API = "responses"

legacy route only: $env:COPILOT_PROVIDER_AZURE_API_VERSION = "2024-10-21"
