Musk admits xAI was not built right first time

Prior position: Musk founded xAI in July 2023 and launched its first model, Grok, in November 2023, publicly positioning it as a direct competitor to OpenAI's ChatGPT and Anthropic's Claude. He promoted Grok as less restricted than rivals and described the company's mission as understanding the universe. The admission marks a sharp departure: Musk acknowledged not only that Grok was lagging on coding — he told a conference audience earlier in March 2026 that 'Grok is currently behind on coding' — but that the foundational architecture of the company itself needed to be rebuilt from scratch. Musk compared the situation to a similar structural reset at Tesla.

The statement came amid multiple executive departures at xAI and followed news that the company had hired two senior leaders from Cursor, an AI coding startup raising funds at a $50 billion valuation. The hire signalled that xAI was trying to catch up on coding — the most commercially valuable AI application of 2026, where Anthropic and OpenAI had taken a clear lead. This is the first time Musk publicly described xAI's original build as fundamentally wrong rather than iteratively behind.
