Questions

About GPT-5 Image Mini on OSMEXO

How much does GPT-5 Image Mini cost through OSMEXO?
$1.00 per 1M input tokens and $0.80 per 1M output tokens, billed per request from prepaid credits. That is 60% below OpenAI’s list price of $2.50 / $2.00. The price on this page refreshes from the catalog every few minutes.
Is this the same GPT-5 Image Mini as calling OpenAI directly?
Yes. Routes are checked with a real generation before they are enabled and re-checked continuously; a provider that fails or drifts is removed from rotation. Media models are verified by output, not by token fingerprint.
How do I call GPT-5 Image Mini with the OpenAI SDK?
Use the OpenAI-compatible image endpoints at https://api.osmexo.com/v1 with your OSMEXO key and the model id openai/gpt-5-image-mini. The model page in the dashboard shows the exact request shape and lets you run one in the playground first.
Why is GPT-5 Image Mini “on request”?
The model is in the catalog but not yet enabled for every key, usually because its routes are still being verified or a vendor key is pending. Ask from the contact form or the dashboard and it is normally enabled within a business day.
