Transparent pricing
Compare model pricing
Compare pricing in USD per 1M tokens. Official reference from models.dev.
Max 50x prices use plan value (weekly credits vs plan price) so $1 of plan goes further than PAYG top-up (26 credits = 1 USD).
| Model ID | Input | Output | Cache write | Cache read | Savings |
|---|---|---|---|---|---|
* Effective USD using Max 50x plan value (weekly credits vs plan price), not PAYG top-up rate.
