GitHub Copilot
by GitHub (Microsoft)
AI pair programmer with inline completions plus a multi-step coding agent
Last reviewed 2026-06-18
GitHub Copilot is GitHub's AI coding assistant. It began as a code-completion tool built with OpenAI and is now a multi-surface product spanning inline completions, chat, in-IDE agent mode, a cloud coding agent, and a CLI. It works inside VS Code, Visual Studio, JetBrains, Eclipse, Neovim, the terminal, and GitHub.com. A defining feature is model choice: paid users pick among OpenAI GPT models, Anthropic Claude, Google Gemini, and other models hosted via GitHub's infrastructure. Beyond inline suggestions, Copilot's cloud agent can be assigned a GitHub issue and work in the background: it spins up an isolated session on its own branch, iterates on a plan, runs tests, and opens a PR for review. Billing moved toward a usage-based model in 2026 with premium-request quotas, while code completions remain unlimited on paid plans.
What it can do
Suggest inline code completions
CopilotAutocompletes lines, blocks, and whole functions as you type, across many IDEs, with the developer accepting or rejecting each suggestion.
sourceRun agent mode for multi-file edits
SupervisedIn-IDE agent that plans and edits across multiple files and runs tools, with the developer steering and approving.
sourceWork issues as a cloud coding agent
SupervisedAssigned a GitHub issue, it works in a background session on its own branch, runs CI, and opens a PR for human review.
sourceAutomated code review
SupervisedReviews pull requests, can address review comments, and helps fix failing checks before a human merges.

Strengths
- +Deepest ecosystem reach: works in nearly every major IDE plus natively on GitHub, with a free tier
- +Real model choice across OpenAI, Anthropic, and Google under one subscription
- +Full ladder from autocomplete to a background cloud agent that opens PRs
Limitations
- −2026 usage-based premium-request billing is confusing; quotas and overages can surprise users
- −The most agentic features gate the strongest models behind higher tiers
- −Inline suggestion quality varies by language and codebase and requires developer verification
Overview
GitHub Copilot is GitHub's AI coding assistant, now spanning inline completions, chat, in-IDE agent mode, a cloud coding agent, and a CLI. It runs inside most major IDEs and on GitHub.com.
What it does
The core feature remains inline completions, where the developer accepts or rejects suggestions (copilot autonomy). On top of that, agent mode makes multi-file edits in the IDE under developer supervision, and the cloud agent can be assigned a GitHub issue to work in the background on its own branch, run CI, and open a PR for review. It also assists with code review.
Integrations & setup
Works in VS Code, Visual Studio, JetBrains, Eclipse, and Neovim, plus GitHub.com, Slack, and Teams. Agent mode supports MCP servers, and GitHub ships an open-source GitHub MCP server. Paid users choose among OpenAI, Anthropic, and Google models.
Pricing
Freemium: a free tier, Pro from about $10/mo, plus Business and Enterprise seats. In 2026 billing moved toward usage-based premium requests, with code completions remaining unlimited on paid plans.
Best for / not for
Best for developers who want AI inside their existing editor and on GitHub, with an optional path to background agents. Less suited to teams wanting a fully autonomous, hands-off engineer.
Alternatives
Cursor is the leading standalone AI editor; Devin targets delegated, async engineering tasks.
