Musk officially announces Grok 4

Musk officially announced that Grok 4.5 is now available on all platforms: It is not as good as Fable, but it is fast, cheap and can work. Musk once again personally posted a new product announcement on social platforms: Grok 4.5 is now available on all platforms. His pitch for the new model is pretty straightforward—it's not as good as the Fable, but it's fast, cost-effective, and gets the job done. In one sentence, Musk neither concealed the gap between Grok 4.5 and the top players, but also nailed its selling point on pragmatism: it is not the smartest one, but the one that runs the fastest, is the most cost-effective, and can get things done best. At a time when the cost of computing power is being repeatedly weighed, using "can complete tasks" as a core label is more like shouting at enterprise-level and daily high-frequency scenarios. via AI News (author: AI Base)
