GitHub is announcing its Copilot X initiative today, an extension of its work on its popular Copilot code completion tool, which originally launched into preview all the way back in 2021. With this, the Microsoft-owned company is launching a code-centric chat mode for Copilot that helps developers write and debug their code, as well as Copilot for pull requests, AI-generated answers about documentation and more. Unsurprisingly, these new features are powered by OpenAI’s GPT-4, though it’s worth noting that, mostly for latency reasons, the code completion tool remains on GitHub’s Codex model, which it derived from GPT-3.
“With the new model coming online, we asked ourselves: what’s the next step? What’s the next step for Copilot? We believe that for auto completion, we nailed that scenario,” GitHub CEO Thomas Dohmke told me.
