GPT-5 Nano pricing by host
A host is a company that runs the model and sells it by the token — the lab that made it, a cloud platform like Amazon Bedrock, Azure or Vertex, or an independent provider.

The price quoted above is the one we publish so that models stay comparable; it is not necessarily the cheapest way to buy this model.
