Assumptions
- Light chat: 15 messages a day, about 2,000 input and 600 output tokens each, 0% of input served from cache.
- Heavy chat: 60 messages a day, about 6,000 input and 1,000 output tokens each, 30% of input served from cache.
- Coding assistant: 120 messages a day, about 20,000 input and 1,500 output tokens each, 60% of input served from cache.
- Heavy coding agent: 500 messages a day, about 40,000 input and 1,200 output tokens each, 85% of input served from cache.
- API cost uses list prices per 1M tokens from our API prices table, with cached input at the cached rate where the provider lists one. No batch discounts or free credits.
- Coding agents resend a lot of context, which is why the agent preset uses large inputs and a high cache share.
- The suggested plan is a rule of thumb: about $45 a month of API usage fits a $20 plan, up to about $320 a month fits a $100 plan, more needs a $200 plan. Vendors do not publish plan limits in tokens, so treat this as a rough guide.
- We compare plans from about $15 a month up, since cheaper tiers often do not include the top model. Team and per seat plans are left out.
- Plans also include apps, tools and features the API does not, and the API has no 5-hour or weekly caps.
