# OpenAI

OpenAI integration — models, BYOK, instrumentation.

OpenAI models are first-class in the Stratix catalog. Browse at [Models catalog](/5.-select-pick-the-model/models-catalog.md).

To use your own OpenAI API key (BYOK), register it as a [BYOK custom model](/5.-select-pick-the-model/byok-custom-models.md) — Stratix will route inference through your key.

To instrument an OpenAI SDK call, see [recipe](/6.-build-wire-your-code/instrument-openai-assistants.md).
