SpaceXAI’s newest AI model Grok 4.5 dramatically undercuts Anthropic and OpenAI on price
Elon Musk’s SpaceXAI Corp. has released a new model called Grok 4.5, in what is its first major launch since it went public a few weeks earlier.
In a blog post earlier today, the company said Grok 4.5 is designed to be a workhorse that’s able to tackle all of the usual tasks that the artificial intelligence industry has been automating for some time already. That includes things like coding, writing emails and presentations, performing office and clerical work, doing research and other kinds of knowledge-based work.
None of this sets Grok 4.5 apart, but SpaceXAI said that the difference is that it can do these tasks just as well as its peers at around half the cost, because it has “twice greater token efficiency” than its peers from other frontier model labs. If true, that could be a compelling advantage in a world where the cost of tokens has suddenly become a major issue for heavy AI users.
SpaceXAI announced Grok 4.5’s release alongside a host of benchmark results that highlight how competitive it is with the leading models of some of its major competitors, and it falls just short of their performance.
