Woofun AI reports that Elon Musk has disclosed the progress of the upcoming large model under SpaceXAI, stating that initial training for the 2T-parameter system will conclude next week. The new model aims to exceed the capabilities of the 1.5T-parameter Grok 4.5 in all aspects while potentially outperforming Kimi K3, with Musk emphasizing the retention of similar generation speed and token efficiency to Grok 4.5.

Artificial Analysis data indicates Kimi K3 holds an AI index of 57 compared to Grok 4.5's 54, with task costs of $0.94 and $0.31 respectively. Although Grok 4.5 currently exhibits slightly lower performance, its cost is approximately one-third that of Kimi K3, highlighting the efficiency gap the new 2T model seeks to bridge.
