Grok 4.6 gets Aug. 7 launch date, Grok 4.7 follows

Elon Musk has set an early August target for Grok 4.6 and disclosed plans for a larger Grok 4.7 model as SpaceXAI steps up its competition with OpenAI, Anthropic, and China’s Moonshot AI. Summary Grok 4.6 is scheduled for around Aug. 7, according to Musk. The upcoming model will have 1.5 trillion parameters and improved post-training. Grok 4.7 could arrive weeks later with 2.1 trillion parameters. Grok 4.5 ranked first for cybersecurity price-performance in a Vercel assessment. Grok 4.6 targets an Aug. 7 release Musk disclosed the timeline in a July 28 post on X, saying Grok 4.6 would be released “around August 7.” He described it as a 1.5 trillion-parameter model with stronger supervised fine-tuning and reinforcement learning. Interesting. Grok 4.6 releases around August 7. This will be the 1.5T model with significantly improved SFT & RL.Grok 4.7 will be the 2.1T model released a few weeks later. This will be better than 4.6 in every way, except slightly slower to serve, albeit with even better… https://t.co/dJjXVnFwoA— Elon Musk (@elonmusk) July 28, 2026 Supervised fine-tuning trains a model on selected examples to improve the quality of its responses.
