Grok 4.5 Arrives in GitHub Copilot With an Enterprise Admin Gate
GitHub says Grok 4.5 is rolling out across Copilot clients and supports text and image inputs. For Business and Enterprise, administrators must enable its policy; GitHub's internal test comments are not independent performance evidence.
What happened and why it matters
Model access is a governance and routing decision, not a substitute for task-level evaluation.

What GitHub announced
GitHub lists supported Copilot plan tiers and clients, including IDEs, the CLI, cloud agent, and Copilot app.
The changelog says rollout is gradual, so listed availability is not a claim that every account has immediate access.
The enterprise decision
For Business and Enterprise, the Grok 4.5 policy is off by default. That puts model enablement under administrative control.
A model-picker addition should therefore be reviewed alongside data, billing, and governance settings.
How to read the performance language
GitHub describes internal testing on terminal coding tasks. That is useful product context but is not an independent benchmark with public methods and comparable baselines.
Teams should run their own approved-task evaluation before changing defaults.
Evidence boundary
This page reports a dated event from a named primary source. Company specifications and adoption statements remain attributed claims unless independent evidence is cited above.
