How we rate models

Quality. Three brains is top, one is basic. We anchor the rating on Artificial Analysis Image Arena — a head-to-head leaderboard where people pick which image they prefer.

Fast. Shown when a typical image generates in under eight seconds. 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.
