- Quality. Three brains is top, one is basic. We anchor the rating on SWE-bench Verified — the 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.
