GitHub Copilot (often referred to as “Copilot X” in earlier announcements) is Microsoft’s flagship AI coding assistant, integrated into IDEs like VS Code, Visual Studio, JetBrains, and more. Launched in 2021 and continuously upgraded, it’s now powered by multiple top models (GPT-5.1 series, Claude Opus 4.5, Gemini 3 Pro) for code completions, chat, agents, and reviews. In 2025, with features like coding agents, premium model access, and enterprise knowledge grounding, it’s the most adopted AI dev tool—boosting productivity by 55% on average while maintaining code quality. G2 scores 4.7/5; devs love the seamless suggestions, but note occasional hallucinations on complex logic.
