Pricing · Spring promo

List price visible. Promo price honest.

Every model shows both the provider list price and our promo rate. Recharge prepaid USD in the customer console, create an API key, switch models by name.

Model rates · per 1M tokens

Three live routes. Two on promo.

Promo prices apply through 5/31; rates revert to list afterwards. DeepSeek stays at its always-on low rate.

Formal customer flow: open the console, register or sign in, recharge credits, create an API key, then call https://api.modelbridgeapi.com/v1. The old standalone dashboard checkout is no longer part of the customer path.
