[Cloudflare AI Gateway](https://developers.cloudflare.com/ai-gateway/) proxies requests to your LLM
provider. You can send its traces to Phoenix two ways:

* **Export gateway spans**: the gateway emits an OpenTelemetry span for every request it proxies,
  with no code in your application.
* **Instrument your app**: trace the OpenAI client with OpenInference so Phoenix captures the full
  input and output messages, while your app still routes requests through the gateway.
