What happened

The GitHub Copilot app now supports bring your own key (BYOK), so you can run agent sessions against your own model providers, including OpenAI, Azure OpenAI, Microsoft Foundry, Anthropic, LM Studio, Ollama, and any OpenAI-compatible endpoint. Keys are stored in the local OS keychain and are never read back by the UI , per the GitHub changelog. The same release notes flag that Copilot CLI's new terminal interface is generally available .

What it means

BYOK is mostly catch-up — Copilot Chat and the CLI already had versions of this — but extending it to agent sessions is the meaningful piece. It detaches the harness (Copilot's tools, IDE integrations, audit) from the model, which is what regulated buyers in finance, legal, and healthcare have been asking for. The trade GitHub is making is visible in the docs: usage is tracked by your provider, not GitHub Copilot, and BYOK requests do not count against Copilot premium request quotas . Read that as GitHub conceding the model layer to win the agent layer.

Today’s Take

Two stories ran on the same day from opposite ends of the agent deployment curve. Anthropic and MoEngage shipped the infrastructure to put agents inside the seats where decisions about employees and customers actually get made. A federal judge in San Francisco told the largest HR software vendor in the country that designing those agents from California means California discrimination law follows the agent wherever it acts. The shape of the day is a widening gap between deployment velocity and accountability velocity — and the buyers who close that gap deliberately, in contracts and audit logs, will own the next eighteen months. The ones who don't will discover that "the vendor did it" is no longer a defense.
