How billing works. The rate above is what usage costs against your prepaid credits on a paid plan — no per-token markup, and Zylo's flat 25% platform fee applies only when you add credits. The free Basic plan instead gives a daily allowance of Basic-tier models (10 requests/min, no card, no credits). Devstral 2512 requires the Go plan or higher — the free Basic plan only includes Basic-tier models. Prices update live from our catalogue.
