SpaceXAI has launched Grok 4.5, pitching the model to developers and enterprises trying to control the rising cost of AI-assisted software development.

In a statement, the company said the model is priced at $2 per million input tokens and $6 per million output tokens. It said the model is built for coding and agentic work, runs at 80 tokens per second, and uses fewer tokens than comparable models on some software engineering tasks.

Grok 4.5 is available through the SpaceXAI console and Grok Build. It is also available in Cursor, the AI coding tool made by Anysphere, giving SpaceXAI a route into a development environment already used by programmers rather than only competing through an API. SpaceXAI said EU availability is expected in mid-July.

In June, SpaceX, which owns SpaceXAI, said it was buying Anysphere, the startup behind Cursor, in a deal aimed at strengthening its position in enterprise AI tools. In a separate statement, Cursor said that Grok 4.5 was trained jointly with SpaceXAI and used trillions of tokens of Cursor data, including user interactions with codebases and software tools.

The launch addresses a growing realization among enterprise engineering teams that AI coding agents can become expensive once they move beyond simple prompts.
