SpaceXAI releases flagship Grok 4.6 model with advanced reasoning capabilities
SpaceXAI today released Grok 4.6, a large language model that it says can outperform Anthropic PBC’s Claude Fable 5 in some areas.
SpaceXAI was known as xAI until last month. The Elon Musk-founded artificial intelligence provider rebranded in connection with its acquisition by SpaceX Corp. In June, the combined company listed its shares on the Nasdaq via the biggest initial public offering on record.
Grok 4.6 is rolling out only a month after SpaceXAI released its previous flagship LLM. According to the company, one of the main improvements is that its engineers spent more time training the former model. The extended training run used an AI-generated dataset designed to improve Grok 4.6’s reasoning capabilities. SpaceXAI also provided the model with access to “high-quality engineering data.”
The initial training run was followed by two additional development steps. The first used a training method called supervised fine-tuning, or SFT, while the second used reinforcement learning.
