Elon Musk said SpaceXAI will release Grok 4.7 in 10 days; the model expands its base to 2.1 trillion parameters from 1.5 trillion and incorporates supplemental SpaceX company data in training. Following Grok 4.6 (shipped Aug 12) which scored 61 on the AA Intelligence Index, the accelerated release cadence and unique engineering dataset could strengthen AI-driven crypto security, DeFi analytics, token launch tooling and broader adoption.

In Brief

Musk says Grok 4.7 arrives in 10 days and will exceed all current models.
The team added SpaceX company data to the model in supplemental training.
Grok 4.7 runs on a 2.1 trillion parameter base, up from 1.5 trillion.

Elon Musk said Grok 4.7 will be released to the public in 10 days and that the model will surpass every AI model currently available.

The release follows Grok 4.6, which SpaceXAI shipped on August 12. It also comes as OpenAI announced that its new Astra model will be launched soon.

SpaceX Data Sits at the Center of Grok 4.7

Musk has built the case across a run of posts. He said in mid-August that initial training had finished and that SpaceX company data was being incorporated through supplemental training.

Musk had earlier detailed the architecture. Grok 4.7 runs on a 2.1 trillion parameter base, up from the 1.5 trillion parameter foundation behind Grok 4.6. He said the larger model runs slightly more slowly while using tokens more efficiently.

He also named the rival he expects to trail him.

“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 post read.

Meanwhile, the release cadence has tightened. SpaceXAI took Grok 4.5 public in July and shipped Grok 4.6 on August 12.

Grok 4.6 Benchmarks Set the Bar

Grok 4.6 was built on its predecessor, Grok 4.5. The company said the model has a “particular focus on long-running agents and more ambitious interactive and visual work.”

According to figures shared, the model scored 61 on the AA Intelligence Index, level with GPT-5.6 Sol Max and behind Claude Fable 5 Max at 62. Grok 4.5 scored 56.

Grok 4.6 led GDPVal-AA v2 with 1753. Yet it managed 26% on Terminal-Bench v3.0, well behind GPT-5.6 Sol Max at 34.6%.

Grok 4.5 set a similar pattern. It topped Artificial Analysis’s AutomationBench-AA at 51.4% while costing $0.34 per task. However, it logged 0.63 guardrail violations per task, above Claude Opus 4.8’s 0.55.

Musk has now attached a firm number to the release. Whether SpaceXAI ships independent evaluations will determine how far the engineering claim travels.
