GitHub Copilot hits 15m users and 85m pull request reviews

GitHub's Copilot artificial intelligence software developer assistance tool has genuinely evolved to become a true peer programming agent, boosting software developers worldwide.

Some of the information Microsoft announced includes:

• GitHub Copilot has surpassed 15 million users, growing more than 4x year-over-year. 

• Year to date, GitHub has shipped 85 Copilot updates — including features like MCP support, expanded model support, bring your own key, and next edit suggestions.

• Copilot’s code review agent has already reviewed over 8 million pull requests. This adds to other Copilot agents like Autofix, which helps devs remediate vulnerabilities, and Agent Mode in VS Code, which can iterate on code, recognise errors, and fix them automatically.

• And companies like Twilio, Cisco, HPE, SkyScanner, and Target, continue to choose GitHub Copilot to equip their developers with AI throughout the entire dev lifecycle

GitHub CEO Thomas Dohmke said, "This momentum was made possible by the dedication of our employees, VS Code and GitHub teams being committed to rapidly evolving our product with sustained velocity. Year to date, we've posted 85 changelogs for GitHub Copilot, from MCP support to bring your own key or next edit suggestions – and we’re not stopping there."

"With agent mode in VS Code, Copilot can now iterate on code, recognize errors, and fix them automatically. This comes in addition to other Copilot agents like Autofix, which helps developers remediate vulnerabilities, and our code review agent, which has already reviewed over 8 million pull requests."

"What started as the first AI pair programmer is soon evolving into a SWE agent, embedded right where your code lives – and with it, GitHub itself will become not only the home of your repos, but also for your agents."
