Elon Musk has signaled a rapid rollout for xAI’s next Grok models, saying Grok 4.6 is due in two weeks and Grok 4.7 four weeks after that. The announcement does not include technical specs, but coverage of the announcement places the likely Grok 4.6 window in early August 2026 and Grok 4.7 in late August 2026. Some reports describe Grok 4.6 as a 2-trillion-parameter model, but xAI has not provided a full public technical specification in the available reporting. One report says the model is a direct successor to Grok 4.5 and places training completion around late July 2026, while another notes that Musk’s public statement implied a launch window in early to mid-August 2026. No official launch page, pricing details, or benchmark data for Grok 4.6 or Grok 4.7 are confirmed in the sources reviewed. Recent reporting shows xAI has been iterating aggressively on the Grok family, with Grok 4.5 already positioned as a strong model for coding, agentic tasks, and knowledge work.
