GitHub Copilot CLI's New Terminal Interface Reaches General Availability

GitHub Changelog·medium signal

GitHub's Copilot CLI shipped its redesigned terminal interface to GA on June 23, 2026, consolidating the agent experience in the shell after earlier previews added BYOK/local-model support, prompt scheduling, voice input, and enterprise-managed plugins. This keeps Copilot competitive with Claude Code and Codex in the terminal-agent category. For builders standardizing on a CLI harness, Copilot CLI now offers a stable interface plus local-model routing for cost control.
