Musk Claims SpaceX Will Reach GPT-6 and Fable-Level AI Capability Within Months

Elon Musk said SpaceX aims to develop an AI model matching the capabilities of Anthropic's Fable and OpenAI's GPT-6 within two to three months, backing the claim with the company's aggressive monthly model release schedule and growing computational resources. The statement comes on the heels of SpaceXAI's September 21, 2026 release of Grok 4.7, which achieved a 1,657 Elo rating on the AA-Briefcase benchmark—a significant 111-point improvement over Grok 4.6 but still trailing Claude Opus 5, the current frontier model.
