GitHub Copilot
Overview
GitHub Copilot is the oldest AI coding assistant, born from the GitHub × OpenAI collaboration. In 2026, it goes far beyond completion with Agent Mode, Coding Agent, Spark, and Agentic Code Review. Agent Mode became GA on both VS Code and JetBrains in March 2026.
Key Features
Agent Mode (GA March 2026)
Autonomous coding agent, now GA on both VS Code and JetBrains. Multi-step tasks consume premium requests.
Agentic Code Review (March 2026)
Code review now gathers full project context and can pass suggestions directly to the coding agent for automatic fix PRs.
GitHub Spark
Pro+ and Enterprise only. Describe an application in plain English to get generated code with live preview.
Semantic Code Search
Finds conceptually related code instead of keyword matches. Describe "login bug" to locate auth middleware even without the word "login."
Model Selection
Choose from multiple AI models including Claude Opus 4 and OpenAI o3 (Pro+ and above).
