GitHub previews Copilot X beyond code completion

GitHub unveiled Copilot X on 22 March: a vision extending its coding assistant into chat, pull requests, documentation and the command line.

The announcement adopts GPT-4 for pull-request and documentation work. Pull-request descriptions enter technical preview; documentation answers and command-line help have waitlists. Internal-repository documentation support remains planned.

Copilot X is not a generally available bundle. Developers must distinguish experimental access from features they can already use.

That distinction follows February’s broader Copilot for Business release. GitHub opened it to Free, Team and Enterprise Cloud customers, with administrator controls for licences and policies. The existing business offering and the new Copilot X previews therefore have different availability.
