How we rate models

Quality. Three brains is top, one is basic. We anchor the rating on SWE-bench Verifiedthe industry-standard coding benchmark — how often a model solves real GitHub issues end-to-end.
Fast. Shown when the model can produce at least roughly 80 tokens per second (about 60 words a second). Not every model qualifies.
$$$$$$
Cost. Single dollar is the cheapest tier (green), three dollars is the priciest (amber). We bucket models relative to the other models you can pick from on Zo, so the tier is meaningful across providers.

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.
