I tested the same prompt at low res and high res. The composition was identical. The credit cost wasn't.
Look at the two images below.
Same prompt. Same model. Same result.
One cost a fraction of the other.
Here's the thing most people don't understand about AI image generation — the model builds your composition first. The resolution just determines how sharp the final print is.
The workflow:
Write your prompt
Generate at low res — fast, cheap, done in seconds
If the composition is wrong, fix the prompt and test again
Repeat until it's right
Then — and only then — run it at full resolution
Test cheap. Finalise once.
