OpenAI API questions
Pricing, API key, payment: the short answers.
As of November 3, 2026, the OpenAI API costs from 36.7 F CFA (GPT-5 Nano) to 6,233 F CFA (GPT-6 Astra) per 1M input tokens on Tchavi. GPT-5.4 Mini: 550 F CFA input and 3,333 F CFA output per 1M tokens. You pay per use in credits, from a 1,000 F CFA top-up. The table above lists all 29 models with their price.
It depends on the model. Without a discount, you pay a Tchavi margin above OpenAI'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 OpenAI 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 OpenAI key: you do not need a OpenAI account. The same key calls GPT-6 Astra and every other model on Tchavi.
No. Every call to GPT-6 Astra, GPT-5 Nano, or an image or voice model is taken 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. No OpenAI account to open: you call OpenAI with your Tchavi key.
Yes. Tchavi exposes an OpenAI-compatible API: keep your code and change two lines, baseURL (https://tchavi.com/api/v1) and apiKey (your sk-tch-… key), then pass the model name, for example gpt-5.4-mini.
For a large volume of messages, try GPT-5 Nano; GPT-6 Astra is the highest-priced model in the table. Image and voice models have their own price; try them in the playground before you integrate.
No: Tchavi does not store your prompts, including the ones you send to OpenAI. Usage logs hold token counts only.
ChatGPT is OpenAI's consumer app, with its own subscription. For a developer, the "ChatGPT API" means the OpenAI API and its GPT models, which is what Tchavi provides. Tchavi does not give access to the ChatGPT app or to ChatGPT Plus.
