- Copilot Chat allows natural language queries about the codebase directly in the editor
- Supports multi-file editing and automated reasoning with the new 'Agent Mode'
- Free tier is available for individuals, open-source maintainers, and verified students
- Allows users to hot-swap between top-tier models (GPT-4o, Claude 3.5/3.7, Gemini)
Cons
- May occasionally suggest code that introduces security vulnerabilities or bugs if not carefully reviewed
- Context window is sometimes limited, causing the AI to lose track of broader architectural patterns
- Over-reliance by junior developers can hinder the learning of foundational programming concepts
- Advanced enterprise features (like fine-tuning and GitHub integration) are locked behind an expensive tier
