PendingOn July 30, 2026 Musk said Grok 4.6 would 'come out in a week' (~Aug 6). xAI publicly released Grok 4.6 on August 7, 2026 — one day past the implied deadline. It is a 1.5T-parameter model on the same V9 foundation as Grok 4.5, with gains from improved supervised fine-tuning and reinforcement learning. Delivered, one day late. KuCoin (Aug 7 2026) ↗
On July 30, 2026, replying to a post noting Grok 4.5's top ranking on the LaurenBench leaderboard, Elon Musk said xAI's next model, Grok 4.6, would come out 'in a week.' In a separate reply the same day he called it 'a significant improvement.' The claim is a near-term, dated release promise that resolves once Grok 4.6 is publicly available.
