How we rate models

: Quality. Three brains is top, one is basic. We anchor the rating on AA Video Arena + community ranking — head-to-head leaderboards plus reputation from independent reviewers.
: Fast. Shown when the model can generate clips fast enough for quick iteration. Not every model qualifies.
$$$$$$$$$$: Cost.Single dollar is the cheapest tier (green), four dollars is the priciest (amber) — reserved for premium models that cost well above the rest. Tiers sit on a fixed scale of what a typical request costs, so they're comparable across providers and don't shift as the lineup changes.

On Zo, you can choose between all the leading AI models for chatting, research, coding, and generating media. We believe in giving you the power to explore different models so that you can get the best results for any task.
