According to CoinMeta, Musk stated that the yet-to-be-officially released Grok 4.6 briefly appeared in the Cursor model list today, with the page labeling it as “Cursor grok 4.6 fast.” This model is primarily designed for complex, long-running agent programming tasks and features a interface that displays 256k context as well as high effort modes. Although the model cannot be invoked once selected, this leak indicates that Grok 4.6 is not far from its official release. Developers have noticed that the enable_grok_4_6_announcement function switch has appeared on the Grok official website frontend, and its current status is still false, suggesting that the relevant release entry point has been reserved but has not yet been activated.
