A Google Cloud quota entry for grok-4.7 was reported on 17 September 2026, ten days after a dated identifier leaked through Cursor’s configuration. Neither xAI nor Google has announced anything, and both catalogues still stop at Grok 4.6. We set out what the two artifacts actually prove, why a quota row is the strongest pre-launch signal short of a model card, what the Kalshi and Polymarket books price it at, and how it sits against four public release windows that have already passed.

Elon Musk says Grok 4.8 is a 2.5-trillion-parameter model trained with xAI’s new C++ software stack and will start reinforcement learning this week. We check the claim against every parameter count and stack post Musk has made, the delayed Grok 4.7, Grok 4.6’s published benchmarks, and what a 2.5T model means for memory, speed and price.
