Model Usage
Overview
How PrettiFlow uses multiple AI models behind the scenes.
PrettiFlow is multi-model. Instead of relying on a single AI, it draws on several providers and picks the right one for each task automatically — so you get good results without choosing a model yourself.
Why multiple models?
Different jobs have different needs. Quickly understanding your prompt is cheap and fast; generating a whole feature is heavier and benefits from a stronger model. PrettiFlow matches each step to a model that fits.
Speed where it helps
Fast, lightweight models handle quick steps like understanding intent.
Power where it matters
Stronger models handle code generation and complex reasoning.
Reliability
If one provider is down, PrettiFlow falls back to another automatically.
Cost efficiency
Cheaper models on light tasks keep your credit usage low.
