What do Fast, Standard and Pro mean in a model name?
They are the vendor's own quality tiers of the same model: Fast trades detail for speed and price, Pro is the highest quality at the highest price, and Standard sits between — for example a 5-second Veo 3.1 clip is 800 credits on Lite, 1,280 on Fast and 3,200 on the standard model.
The pattern
Vendors ship one model in several configurations, and LUVI lists each as its own entry so that price and parameters are exact. The tier is written into the name:
| Family | Tiers on LUVI | Starting price (credits) |
|---|---|---|
| Veo 3.1 (Google) | Lite · Fast · standard | 800 · 1,280 · 3,200 |
| Seedance 2.0 (ByteDance) | Fast · standard | 1,562 · 1,952 |
| Kling v3.0 (Kuaishou) | Std · Pro | 1,065 · 1,425 |
| Kling O3 (Kuaishou) | Std · Pro | 948 · 1,188 |
| Hunyuan3D (Tencent) | Rapid · Pro | 600 · 1,000 |
| Nano Banana (Google) | 2 · Pro · Pro Ultra | 100 · 175 · 188 |
Prices are for each model's default settings as listed on its page today.
What changes between tiers
- Speed. Fast and Lite tiers return in a fraction of the time.
- Detail and coherence. Pro tiers hold faces, text and motion better over longer clips.
- Options. Some lower tiers have fewer resolutions, shorter maximum duration, or no generated audio. Veo 3.1 Lite, for instance, has no audio switch, while the standard model doubles its price with audio on.
A working habit
Draft on the cheapest tier until the prompt produces the shot you want, then rerun the same prompt on the tier you will publish. The prompting guide is identical across tiers of a family, so the prompt carries over.
Frequently asked
Is Fast always the same model with fewer steps?
Usually a lighter configuration of the same generation. The vendor defines the difference; LUVI passes the tier through unchanged.
Which tier should I start with?
Fast, to test the prompt and the composition. Move to Standard or Pro for the final render once the prompt works.
Do tiers change the parameters?
Sometimes. A Fast or Lite tier may lack a resolution or an audio option that the full model has; the model page lists exactly what each one exposes.
