xAI is expected to launch Grok 4.6 next week, featuring improvements in reasoning, coding, and agentic capabilities mainly through post-training methods like supervised fine-tuning and reinforcement learning on its existing 1.5 trillion-parameter model.
This Wire brief sits within Fusion42's coverage of AI Frontier Models and Generative AI.
◆ ◆ The Wire takeaway
You must prioritise integrating smarter post-training methods over scaling model size to improve AI effectiveness. xAI's focus shift shows that better training may unlock faster, more capable AI even without bigger models.
