xAI starts from scratch again: Musk builds an AI coding tool with a team from Cursor

xAI — Elon Musk's artificial intelligence laboratory — is restarting its AI coding tool development from scratch. The company has acknowledged that the previous version was not done correctly from the beginning, and has decided to completely revise its approach. This is already the second restart of the project in a row, and this time the stakes are higher: xAI is attracting managers precisely from the company that currently sets the standards in this segment.

Two top managers from Cursor have moved to xAI to lead the updated development. Cursor — a code editor with deep integration of language models, owned by Anysphere — has become one of the most popular tools among developers in recent years. Its strength lies not so much in the power of the models, but in understanding the real workflow of an engineer: autocomplete, inline chat, code explanation, refactoring — everything is done to help, not hinder.

It is this experience that is now transitioning to xAI. For Musk's laboratory, a coding tool is a strategically important entry point. xAI was founded in 2023 as an alternative to OpenAI and is currently best known for the Grok model, integrated into the X platform.

But a chatbot is just the first layer. To seriously compete with OpenAI, Google, and Microsoft, you need products embedded in users' daily workflows. Developer tools — one of the most sticky and profitable markets: a well-made tool is used by developers every day.

The segment is, however, extremely saturated. GitHub Copilot from Microsoft, Cursor, Codeium, Amazon CodeWhisperer, Tabnine — each has its own audience and integrations. It's difficult to enter even with strong foundational models.

Cursor's history shows: in this segment, those win who build products around the needs of developers, not around model specifications. This is exactly why the transition of managers from Cursor to xAI is an attempt to buy knowledge about how to build such products correctly. It is notable that xAI does not hide the failure of the previous attempt.

The official acknowledgment that "it was not done correctly from the beginning" — is atypical corporate honesty. Most companies in such a situation would prefer to talk about product evolution or a new phase of development. The fact that xAI calls things by their proper names suggests either a high culture of internal evaluation, or that pressure from competitors leaves no room for embellishment.

If the new team from Cursor can transfer to xAI what made Cursor successful, the laboratory will get a real chance to occupy a place in the workflow of millions of engineers. If not, this will be yet another confirmation: in developer tools, even Musk doesn't get a discount for scale.
