SpaceXAI has released its latest model, Grok 4.5 \u2014 the first since the company went public several weeks ago.<\/p>\n
In a blog post<\/a> published Wednesday, SpaceXAI characterized its new release as a workhorse that can tackle all of the typical tasks that the AI industry has sought to automate: coding and app-building, office and clerical work, research, writing, and other forms of routine knowledge work.<\/p>\n Grok can supposedly do all this for less spend, too, as SpaceXAI says that its model has \u201ctwice greater token efficiency\u201d than other leading models. If it carries through to real-world use cases, that efficiency would be a big advantage for SpaceXAI, since the cost of tokens has been a growing concern for AI consumers.<\/p>\n The company released benchmark metrics Wednesday that appeared to show Grok\u2019s competitiveness with other top models from SpaceXAI competitors, although just short of best-in-class:<\/p>\n In a post<\/a> on his social media platform X (which is a subsidiary of SpaceXAI), founder Elon Musk compared the model to Opus, Anthropic\u2019s LLM designed for intensive and complex tasks.<\/p>\n \u201cBased on strong positive feedback from customers in our beta test program, @SpaceXAI will make Grok 4.5 available to the public tomorrow. It is an Opus-class model, but faster, more token-efficient and lower cost,\u201d wrote Musk in his post on X.<\/p>\n Musk later added<\/a>: \u201cOur internal assessment is that Grok 4.5 is roughly comparable to Opus 4.7, but much faster. The combination of capability, faster speed and lower cost is what makes it competitive.\u201d<\/p>\n SpaceXAI says that its new model costs $2 per million input tokens and $6 per million output tokens. That\u2019s quite competitive, if Grok\u2019s capabilities match SpaceXAI\u2019s rhetoric.<\/p>\n Opus 4.7<\/a>, by comparison, costs $5 per million input tokens and $25 per million output tokens. OpenAI has tiered costs<\/a> for different model versions: Sol, its most expensive, costs $5 for 1 million input tokens and $30 for 1 million output tokens, while its least expensive, Luna, costs $1 for 1 million input and $6 for 1 million output tokens.<\/p>\n It\u2019s a big week for AI model releases. OpenAI is planning to release<\/a> GPT 5.6, its latest, most powerful model, on Thursday. The release of that model had previously been limited by the Trump administration, due to concerns about its security implications. OpenAI has called it<\/a> its \u201cstrongest model yet.\u201d<\/p>\n<\/div>\n When you purchase through links in our articles, we may earn a small commission<\/a>.
