Musk once again personally announced the new product on the social platform: Grok 4.5 is now available on all platforms.

He clearly defined the positioning of this new model — although it is not as good as Fable, it is very fast, cost-effective, and can get the job done. In one sentence, Musk neither concealed the gap between Grok 4.5 and the top performers, nor did he hide its selling points, emphasizing practicality: it may not be the smartest, but it is the fastest, most cost-effective, and most capable of getting things done.

Given the current emphasis on computing power costs, labeling "getting the job done" as the core feature seems to be a direct call to action for enterprise-level and daily high-frequency scenarios.
