Musk tells Tesla staff to switch to Grok — a model he admits is worse

Elon Musk told Tesla staff to move to using Grok, the AI model from his own xAI (now folded into SpaceX), according to a memo sent to employees on Friday. The push comes days after Tesla capped employee spending on third-party AI tools — and it lands even though Musk himself concedes Grok is not as good as its rivals.

Why this matters
Why now

This move happens just after Tesla capped employee spending on third-party AI tools, indicating a strategic push to consolidate AI infrastructure and spending within Musk's ecosystem.

Why it’s important

It demonstrates a strong strategic imperative for Elon Musk to integrate xAI's Grok deeply within his owned companies, even at the cost of perceived performance, aiming for vertical integration and control over his AI assets.

What changes

Tesla employees are now directed to use Grok, potentially shifting internal development and data flows towards xAI's model, impacting reliance on external AI providers within Tesla.

Winners
  • · xAI
  • · Tesla (long-term data integration)
  • · Elon Musk (ecosystem control)
Losers
  • · Third-party AI tool providers
  • · Tesla employees (potential short-term productivity hit)
Second-order effects
Direct

Tesla's internal operations and product development will increasingly be powered by Grok, generating valuable feedback and training data for xAI.

Second

Other companies within Musk's portfolio (e.g., SpaceX) may follow suit, accelerating Grok's adoption and development across the 'X' ecosystem.

Third

This could lead to a highly integrated, proprietary AI stack across Musk's ventures, potentially creating a unique competitive moat but also risking internal resistance if Grok's performance lags significantly.
