The Copilot Coding Agent already supported a selectable model set for delegated coding tasks.
GPT-6.1 Sol is documented as a generally available model option for the GitHub Copilot Coding Agent.
GitHub made GPT-6.1 Sol generally available in GitHub Copilot on September 29, 2026 and explicitly names the GitHub Copilot Coding Agent as a supported surface. The model can be selected through the model picker for delegated coding work.
The relevant change for AgentenCode is not the model release alone, but its direct connection to the Coding Agent. Delegated repository tasks can now run on another selectable model without changing the basic workflow: the agent works asynchronously and returns code changes for review.
GitHub lists Copilot Pro+, Max, Business and Enterprise among supported plans and says the rollout is gradual. Business and Enterprise administrators can control access with the Copilot Model Policy, so organizational model availability can differ from consumer availability.
GitHub also reports efficiency improvements from its own early testing. AgentenCode treats those performance statements as provider claims rather than independent benchmarks. Repository permissions, network access, sandbox boundaries and review processes remain separate evidence fields.
