Elon Musk stated that Grok 4.6, described as a 1.5T model with significantly improved supervised fine-tuning and reinforcement learning, is scheduled to release around August 7. It will be followed weeks later by Grok 4.7, a 2.1T model that improves on every dimension except inference speed while delivering better token efficiency. The statements come from Musk in his role as xAI founder and were summarized from public posts. No independent confirmation of the exact dates or parameter counts has been provided beyond the announcement itself.
