$0.06 per million input tokens and $0.48 per million output tokens, charged per request from your prepaid balance. You need a small balance to start ($1 for most models); there is no monthly fee.

Does it work with the OpenAI SDK?

Yes: set base_url to https://api.gridpup.com/v1/ai and the model to openai/gpt-5-nano.
