Zro plans and what they include
Zro has no free tier, but a one-time $5 usage credit needs no subscription and no recurring charges. Pro is $20 per month ($16 per month billed yearly) with an expected usage of about 1B tokens a month, an estimate rather than an allowance. It includes open coding models, an OpenAI-compatible API, the Zro CLI launcher and agent tools. Max is $60 per month ($48 per month billed yearly) for about 5B tokens a month and everything in Pro.
Usage packs top up beyond the monthly budget at $5, $10, $20, $50 or $100, with or without a subscription. Team / Enterprise is custom-priced and offers a formal DPA. Prices checked on 2026-09-29.
