Questions about this prompt

Which AI model is this sci-fi prompt written for?

It was written and tested for Midjourney, but the format buttons above rewrite it for Midjourney, Stable Diffusion, DALL·E, Flux, Ideogram and Leonardo, so you can paste it into the tool you already use.

Can I change the aspect ratio or style?

Yes. The prompt is set for 16:9, which suits this composition. In Midjourney change the --ar value; in other apps pick the size in settings. Use the remix panel to swap the style, lighting, camera or mood without rewriting the whole prompt.

Is this prompt free to use for commercial work?

The prompt text is free to copy, edit and use. Whether you can sell the image depends on the terms of the AI model that generates it, so check your plan on that platform before using results commercially.
