 By default this blueprint uses an ensemble of 3 LLMS to generate podcasts. The example uses the LLama 3.1-70B NIM for balanced performance and accuracy. To use a different model, update the `models.json` file with the desired model. The default `models.json` calls an NVIDIA-hosted NIM. Feel free to use it as you develop locally. When you deploy, please use our NIM API Catalog endpoints.

 It is easy to swap out different pieces of the stack to optimize GPU usage for available hardware. For example, minimize GPU usage by swapping in the smaller LLama 3.1-8B NIM and disabling GPU usage for `docling` in `docker-compose.yaml`.

 We expose a Jaeger instance at `http://localhost:16686/` for tracing. This is useful for debugging and monitoring the system.
