SpaceXAI schedules rapid release of Grok 4.6 and 4.7 AI models

Elon Musk announced on X that SpaceXAI will launch Grok 4.6 in two weeks and Grok 4.7 in four weeks. Grok 4.6 is expected to be a roughly two‑trillion‑parameter model, a substantial increase from the 1.5 trillion parameters of Grok 4.5, and will be trained with proprietary engineering data from SpaceX. The company, formerly xAI, rebranded to SpaceXAI in July 2026 to emphasize integration with SpaceX’s operational infrastructure.

No independent benchmarks, pricing details, or technical specifications were provided. Analysts note that the market will monitor whether Musk meets the announced dates, when third‑party evaluations become available, and whether enterprise customers adopt the models. Speculation suggests Grok 4.7 could contain between four and six trillion parameters, aiming to match or exceed competitors while retaining the speed and token‑efficiency of earlier versions.
