SpaceXAI, owned by billionaire Elon Musk, launched this Wednesday (8) what it considers to be its most intelligent artificial intelligence model.
Named Grok 4.5, it was created mainly to help users program codes and perform office tasks, such as creating spreadsheets and complex presentations.

According to the company, the model can create applications from scratch even if the commands have few details and create files with various program resources such as Excel and PowerPoint.
In tests on long-term reasoning and the use of AI agents, Grok 4.5 came close to Opus 4.8, an Anthropic model considered one of the most powerful in the world.

In comparisons, it was behind competitors such as GPT 5.5, from OpenAI, and Fable, an Anthropic model considered so advanced that it had to undergo restrictions on sensitive issues.
Grok 4.5 was trained from data sets on programming, science, engineering and mathematics, explained SpaceXAI.
The company highlighted that its new model is twice as efficient as rivals, which, in theory, allows users to solve tasks in fewer steps and use fewer tokens.
AI tokens are the amount of information sent and received in interactions with AI models. Each word, part of a word and punctuation marks can be considered tokens.
In a statement, SpaceXAI said Grok 4.5 costs $2 per million input tokens and $6 per million output tokens. The price costs less than half that charged by competing models.
Grok 4.5 is available on Grok Build, on the SpaceXAI panel and on Cursor, three exclusive systems for subscribers.
