GitHub Copilot is Microsoft/GitHub's AI pair programming assistant, providing real-time code suggestions, chat, and agentic coding capabilities directly inside IDEs like VS Code, JetBrains, and Visual Studio. As of mid-2026, Copilot shifted to usage-based billing with a new lineup of individual plans: Free (2,000 completions/month, 50 premium requests), Pro ($10/month, $15 included usage with flex allotment), Pro+ ($39/month, $70 usage), and Max ($100/month, $200 usage). All paid plans include unlimited code completions and next-edit suggestions; credits apply to chat and agent usage. Model access is broad, including Claude Opus 4.5/4.6/4.8, Gemini 2.5 Pro, GPT-5.2, and GPT-5.4 series. For teams, Copilot Business runs $19/user/month and Enterprise $39/user/month, adding centralized management, policy controls, and IP indemnification. As of April 2026, new sign-ups for individual paid plans were temporarily paused, though existing plans can be upgraded.
