AI Coding Assistant
The AI pair programmer from GitHub. Inline completions suggest code as you type, Copilot Chat answers questions and writes tests, and the coding agent can take a goal, edit across files, and open a pull request for review. It works across many IDEs and lets you pick from a multi-vendor model catalog.
Completions
Ghost-text inline suggestions plus next-edit predictions as you type in your IDE
Copilot Chat
Explain code, generate tests, find vulnerabilities, and fix bugs across many editors
Coding Agent
Assign a goal and the agent indexes the repo, edits across files, and opens a PR
Model Catalog
Choose models from OpenAI, Anthropic, Google, and Microsoft (vendor-reported)
Broad IDE Support & CLI
VS Code, Visual Studio, JetBrains, Xcode, Eclipse, and more, plus a terminal CLI (vendor-reported)
GitHub Copilot is GitHub's AI pair programmer. It works in three connected ways: inline completions offer ghost-text suggestions and predict the location and content of your next edit; Copilot Chat answers questions about your code, generates tests, finds vulnerabilities, and fixes bugs across editors and on GitHub.com; and the coding agent takes a goal, indexes the repository, plans, edits across files, validates the result, and opens a pull request for you to review. All figures below are vendor-reported and verified 2026-06-15.
Completions provide ghost-text inline suggestions and next-edit suggestions that predict where and what you will change next. Copilot Chat adds conversational help in VS Code, Visual Studio, JetBrains, Eclipse, and Xcode, on GitHub.com, on mobile, and in the CLI, and it is extensible through the Model Context Protocol.
Copilot lets you choose from models built by OpenAI, Anthropic, Google, and Microsoft, with select frontier models offering extended context and configurable reasoning in VS Code and the Copilot CLI. The catalog changes frequently, so the available models are a moving snapshot; confirm the current list in GitHub's documentation.
GitHub frames Copilot as assistive: suggestions are probabilistic, not code to paste without thought, and human review stays in the loop. Paid plans use a credit model where one credit equals one cent, and heavier work such as premium models or the cloud agent draws more credits. Confirm the current plans and quotas at github.com/features/copilot/plans.
Vendor-reported, verified 2026-06-15. Plan prices, credit allowances, and model lists move quickly; confirm current details at github.com/features/copilot/plans and docs.github.com.

Model Providers
In-depth coverage of GitHub Copilot's plans and pricing, completions, Copilot Chat, the coding agent, supported models, and how it compares with Cursor. Researched with vendor documentation and honest trade-offs.
The AI pair programmer explained: how completions, Copilot Chat, and the coding agent work together, the IDEs it supports, and how the free and paid plans differ.
Free, Pro, Pro+, Business, and Enterprise tiers broken down, plus how the credit model works at one cent per credit and what premium usage actually draws (vendor-reported).
A walkthrough from setup to first results: installing the extension, accepting inline completions, asking Copilot Chat for help, and reviewing what the assistant suggests before you keep it.
The in-IDE assistant against the agent-native editor: Copilot's broad IDE support and multi-vendor model catalog versus Cursor's editor-first agent, with an honest read on where each fits.
How the coding agent takes a goal, indexes the repository, edits across files, validates the result, and opens a pull request for review, plus the integrations it connects to.

Important context for responsible AI adoption
GitHub Copilot is a cloud service: your prompts, the code in your editor, and the agent's actions are processed through GitHub's infrastructure and your chosen model providers. Business and Enterprise plans add centralized policy controls, and GitHub publishes data-handling and trust documentation for Copilot. Free and individual plans differ from organization-managed plans in the controls available, so review GitHub's current Copilot Trust Center and privacy documentation, and prefer enterprise controls before processing sensitive or proprietary code.
Coding assistants like GitHub Copilot speed up output, but long agent-driven sessions can blur into overwork, and the ease of generating code should not replace rest, review, or real connection. If you are experiencing distress:
AI systems can produce plausible-sounding but incorrect guidance. For mental health, medical, legal, or financial decisions, always consult a qualified professional.
See the NIST AI Risk Management Framework for structured guidance on AI risk assessment.
Under GDPR (EU) and CCPA (California), you have the right to access, correct, and delete your personal data. AI coding tools can produce confident but wrong output, so GitHub itself frames Copilot as assistive, not autopilot. Always review agent edits and suggestions before merging, and validate generated code against your own tests and security review.
The EU AI Act sets transparency obligations for generative AI, including disclosure of AI-generated content. Organizations adopting AI coding tools remain responsible for meeting these provisions and for the code they ship.
