SDXL Fast vs Realistic Vision
Same 26 credits, same architecture, both take LoRAs — this is base model versus fine-tune. SDXL is the general base: it will attempt any style you prompt for, and it is the right host for a LoRA that supplies the look. Realistic Vision is tuned for photorealism and gets there without help.
So the choice is really about where the style is coming from. If a LoRA provides it, start from the neutral base. If you want photoreal output straight out of the box at the cheapest tier, Realistic Vision is already pointed that way.
Choose SDXL Fast if
- A LoRA is supplying the style
- You want a neutral starting point
- The subject is not photographic
Choose Realistic Vision if
- You want photoreal output with no LoRA
- Portraits and interiors on a budget
- You do not want to fight the base model toward realism
