FAQ

What is the OpenAI API?

The OpenAI API is an interface that lets you integrate GPT models — including GPT-5, GPT-4o, and GPT-4 — directly into your projects to generate text, process data, build chatbots, and automate tasks. Through Serverspace, you get access to the OpenAI GPT API alongside models from other providers through one connection.

Is GPT-5 API pricing different from GPT-4o or GPT-4?

Yes — pricing varies by model generation and capability tier. As a rule of thumb, more capable, larger models cost more per token than smaller or older ones, so the right choice depends on whether your task needs top-tier reasoning or can run on a lighter, cheaper model.

Can I use the GPT API to build a chatbot?

Yes. Simply connect your bot to the API through an endpoint and choose the model you want to use. The integration works with virtually any platform — websites, applications, messaging platforms, or internal systems — allowing your bot to understand questions, generate natural responses, and maintain contextual conversations.

How do I get an OpenAI API key?

Sign up, choose the GPT model you need, and generate your API key directly from the dashboard — no infrastructure setup or model training involved. You can start making requests within minutes.
