The GitHub Copilot assistant, which recently gained an agent mode feature to help it compete with Cursor and Windsurf, now has over 15 million users, four times more than a year earlier, Microsoft CEO Satya Nadella told analysts on a conference call earlier this month.

A free Copilot tier for individuals provides limited access.

The new coding agent won’t be free, though. It will be available to developers with Copilot Pro+ subscriptions and organizations that subscribe to the Copilot Enterprise service tier, GitHub said. It’s available in preview, meaning that GitHub will take early user feedback, the spokesperson said.
