Copilot coding agent model picker for Copilot Business and Enterprise

Source: GitHub Changelog

Copilot coding agent

Copilot coding agent is an asynchronous, autonomous background agent. Delegate a task to Copilot, and it works in its own development environment in the cloud. When the work is finished, Copilot opens a pull request and requests your review.

Model selection for Business and Enterprise

In December, we launched model selection for Copilot Pro and Pro+ users. Today, the model picker is also available to Copilot Business and Copilot Enterprise users, allowing you to choose the model that best fits your task.

When assigning an issue to Copilot on github.com, or when starting a task from the agents tab, agents panel, GitHub Mobile, or the Raycast launcher, you can use the dropdown to pick from the following models:

Available models

• Auto
• Claude Opus 4.5
• Claude Opus 4.6
• Claude Sonnet 4.5
• Claude Sonnet 4.6
• GPT-5.1-Codex-Max
• GPT-5.2-Codex
• GPT-5.3-Codex

Auto mode

If you leave the setting on Auto, Copilot optimizes speed and performance by automatically choosing a model based on availability.

Administrator settings

If your administrator has not enabled any of the models listed above, the model picker will not be shown, and Claude Sonnet 4.6 will be used automatically.
