FLUX API pricing per image and API key: one key, one balance

As of November 3, 2026, the FLUX API costs from 17.7 F CFA (FLUX 3) per image, up to 43.3 F CFA (FLUX.2 Flex) on Tchavi. You pay per use in credits, from a 1,000 F CFA top-up. The table above lists all 3 models with their price.

It depends on the model. Without a discount, you pay a Tchavi margin above Black Forest Labs's list price; a discounted model can come out at or even below that list price while the discount lasts. The exact price of every Black Forest Labs model is in the table. What you get for it: one account, one key and one balance for more than 100 models, images and video included; top-ups by mobile money, no bank card needed, with the operator fee absorbed by Tchavi; credits that do not expire.

Create a Tchavi account, top up from 1,000 F CFA, then generate a key in your dashboard. It is a Tchavi key (it starts with sk-tch-), not a Black Forest Labs key: you do not need a Black Forest Labs account. The same key calls FLUX.2 Flex and every other model on Tchavi.

No. FLUX is billed per generated image, from your balance. Top up from 1,000 F CFA; credits do not expire.

Top up with mobile money, no bank card needed: for example M-Pesa in Kenya, MTN MoMo or Airtel Money in Uganda and Rwanda, MTN MoMo in Zambia. Each generation is taken from your balance, per image.

Call FLUX with your Tchavi key (sk-tch-…), like any other model. The guides in the docs give the parameters and code examples for each model type.

In the table, FLUX.2 Flex is the highest-priced model and FLUX 3 has the lowest entry price. Generate a few images with the same prompt before you choose.

No: Tchavi does not store your prompts, including the ones you send to FLUX. Usage logs hold token counts only.
