Elon Musk admits Anthropic model outperforms Grok 4.5 as competition intensifies

Elon Musk has acknowledged that Anthropic’s model, Fable, is currently superior to xAI’s Grok 4.5. Musk noted that Grok 4.5 requires weekly iterations to close the performance gap with frontrunners like Anthropic and OpenAI. This admission coincides with a three-day slide for associated stock as the AI race intensifies.

Why it matters

Enterprise developers must prioritise flexibility in their AI stacks to accommodate shifting performance leaders. The admission that even well-funded labs struggle to maintain parity suggests that model-agnostic architectures are essential for production stability.

Key points

  • Musk concedes that Anthropic’s Fable model currently holds a performance lead over Grok 4.5.
  • xAI aims to implement weekly updates to accelerate the development of its flagship model.
  • The competitive landscape is tightening as labs race to achieve parity with industry leaders.
