Questions

## GPT (OpenAI): frequently asked

Does OpenAI train on data sent through the API?

OpenAI states that API data is not used for training by default, but read the current data usage policy and your contract terms. Azure OpenAI has its own data handling terms.

How do we keep API costs under control?

Track token usage per feature, cache repeated requests, use smaller models where they pass your evaluations and set budget alerts. We build these controls into the gateway from day one.
