GitHub Copilot
An AI-powered coding assistant offering context‑aware code completions, suggestions, chat, and agentic workflows within popular development environments.
What is GitHub Copilot?
GitHub Copilot is an AI-driven code assistant jointly developed by GitHub and OpenAI, first announced on June 29, 2021. It integrates into widely used IDEs (like VS Code, Visual Studio, JetBrains, Eclipse, Xcode, Neovim) and provides features including real‑time code completion, comment‑based function generation, code review assistance, chat interactions, and autonomous agent workflows. Recently, Copilot shifted from a premium request‑unit billing system to a usage‑based AI credits model as of June 1 2026, introducing token‑based pricing for advanced queries while keeping plan prices unchanged.
What you can do with it

Inputs / Outputs
Strengths & Limitations
Strengths
IDE integration breadth
Supported across major IDEs and editors, including Visual Studio Code, Visual Studio, JetBrains IDEs, Eclipse, Xcode, Neovim, etc.
Extensive feature set
Supports code completion, chat-based interaction, code review, Pull Request summaries, and full autonomous agent workflows.
Flexible plan options
Offers Free, Pro, Pro+, Business, and Enterprise plans, catering to individual developers through large organizations.
Recent usage‑based billing aligns cost to use
New billing model adapts costs to actual token usage and model complexity, aiming for fairer pricing.
Enterprise controls
Business/Enterprise tiers include centralized management, policy enforcement, and fine‑tuned private models.
Data transparency and opt‑out
From April 24, 2026, Individual plans’ interaction data are used to improve models unless users opt out; organization plans are exempt.
Limitations
Billing unpredictability
Users report steep cost increases (up to 100‑fold) after shift to usage‑based billing; token consumption may vary unpredictably.
Removed annual subscriptions
Annual billing options have been removed, eliminating upfront discounted pricing.
Free tier limits
Free plan restricts users to 2,000 completions and 50 requests/month, which may be tight for heavy users.
Data privacy concerns
Individual plan interaction data are used for training by default, potentially raising concerns; opting out is manual.
Complex pricing structure
Pricing spans credits, actions minutes, model-specific rates, and overage options, making cost estimation difficult.
Pricing & Plans
Model: Freemium
Free
2,000 completions/month, limited chat/agent usage, CLI access
Pro
Unlimited completions, cloud agent and code review, $15/month AI credits
Pro+
Includes Pro features, premium models (e.g. Opus), audit logs, ~$70/month AI credits
Max
Priority access to new models/features, highest AI credits allotment (~$200/month)
Free tier offers 2,000 completions and 50 chat/agent‑mode requests per month. Pro is $10/month with 300 premium requests and unlimited completions/chat; Pro+ is $39/month with 1,500 premium requests and access to all models. Business and Enterprise tiers available, priced at $19 and $39 per user/month respectively, with organizational controls and higher quotas. Usage beyond plan limits incurs token‑based charges or GitHub Actions minutes for code review/agent tasks.
Who it's for
Ideal for
Individual developers or small teams seeking AI‑powered coding productivity tools, looking for flexible usage with predictable or limited token consumption.
Not ideal for
Users or organizations needing predictable flat‑rate costs or not wanting pay‑as‑you‑use billing, or who prefer no data sharing even with opt‑out mechanisms.
What users say
- High utility in code completion and speed
- Budget concerns after usage‑based billing
- Appreciation for broad IDE support and feature depth
- Frustration about removed annual plans and price unpredictability
Prompts & Results
›Suggest a Python function to reverse a linked list.
GitHub Copilot generates a complete Python function implementation that traverses and reverses list pointers, including docstring and type hints (e.g., using `prev`, `current`, `next_node`).
›Explain what this SQL query does.
Copilot Chat provides an analysis of the SELECT statement, including joins, WHERE conditions, and output columns, written in clear explanatory text.
›Review this JavaScript code for potential bugs.
Copilot identifies issues like unhandled promise rejections, missing variable declarations, and suggests fixes with inline code changes.
›Create a new feature branch, write a simple endpoint in Go, commit, push, and draft a pull request.
In agent mode, Copilot creates a branch, scaffolds a Go web handler, opens a pull request draft with code and a summary, and logs its actions.
FAQ
When was GitHub Copilot first released?+
It was first announced on June 29, 2021, after a technical preview, and made generally available around the Microsoft Build 2022 event.
What changed with the June 1, 2026 billing update?+
GitHub moved from a fixed premium request unit model to a usage‑based token credit system. Plan prices remain ($10 Pro, $39 Pro+, $19 Business, $39 Enterprise), but usage now consumes AI Credits based on token length and model cost; code completions remain included.
Can I opt out of data being used for training?+
Yes. Starting April 24, 2026, individual Free, Pro, and Pro+ users have their data used for model training by default but can opt out; Business and Enterprise users are not affected.
Which IDEs does Copilot support?+
It integrates with Visual Studio Code, Visual Studio, JetBrains IDEs, Eclipse, Xcode, Neovim, and more, including CLI and GitHub Mobile.
