According to reports from SpaceXAI, Elon Musk has confirmed that Grok 4.7 will be released to the public in 10 days, loaded with SpaceX company data that he claims will surpass every rival AI model currently available. The announcement follows Grok 4.6, which SpaceXAI shipped on August 12, and comes as OpenAI announced its new Astra model will be launched soon. Musk has built his case across a series of posts, stating that initial training had finished and that SpaceX company data was being incorporated through supplemental training.
As reported by SpaceXAI, Grok 4.7 runs on a 2.1 trillion parameter base, up from the 1.5 trillion parameter foundation behind Grok 4.6. Musk indicated that the larger model runs slightly more slowly while using tokens more efficiently. The release cadence has tightened significantly, with SpaceXAI taking Grok 4.5 public in July and shipping Grok 4.6 on August 12, demonstrating an accelerated development pace.
According to figures shared by SpaceXAI, Grok 4.6 scored 61 on the AA Intelligence Index, level with GPT-5.6 Sol Max and behind Claude Fable 5 Max at 62. The model led GDPVal-AA v2 with 1753 points but managed only 26% on Terminal-Bench v3.0, well behind GPT-5.6 Sol Max at 34.6%. Grok 4.5 had previously topped Artificial Analysis's AutomationBench-AA at 51.4% while costing $0.34 per task, though it logged 0.63 guardrail violations per task, above Claude Opus 4.8's 0.55.
As reported by SpaceXAI, Musk named the rival he expects to trail him, stating that 'Grok 4.7 will exceed all current models. That said, Anthropic is a great company and will probably release improved models soon. However, the SpaceX training corpus is so awesome & unique that I would be shocked if any model is better at real-world engineering than 4.7'. The company has now attached a firm number to the release, with whether SpaceXAI ships independent evaluations determining how far the engineering claim travels.
The latest developments in the AI market show Anthropic's Fable 5.1, released the week of August 24, 2026, demonstrating significant improvements in speed, token efficiency, and output quality. According to Every AI research subscription, Fable 5.1 outperforms Opus 5 in speed, token efficiency, and output quality, enabling delegation-heavy workflow for complex tasks at roughly half the token cost and twice the speed. This positions Fable 5.1 as a direct replacement for expensive high-token models like Opus 5, making true delegation of coding and knowledge work accessible to average knowledge workers for the first time. The competitive landscape continues to evolve with SpaceXAI's Grok 4.7 approaching release while Anthropic strengthens its position in the AI market.
