 We will offer two options for interacting with the agentic healthcare front desk: with a text / voice based Gradio UI or with a digital human avatar you can converse with.

+> Currently, there is a higher latency expected during LLM tool calling. Interaction with the agent could take a few seconds for non tool calling responses, and could take much higher (30+ seconds) for tool calling responses. If you're utilizing the NVIDIA AI Endpoints for the LLM, which is the default for this repo, latency can vary depending on the traffic to the endpoints. An improvement to this tool call latency issue is in development for the LLM NIMs, please stay tuned.

 You can experiment with other LLMs available on build.nvidia.com by changing the `model` param for `ChatNVIDIA` in the Python files in the directory [`graph_definitions/`](./graph_definitions/).
 
-If instead of calling NVIDIA AI Endpoints with an API key, you would like to host your own LLM NIM instance, please refer to the [Docker tab of the LLM NIM](https://build.nvidia.com/meta/llama-3_1-70b-instruct?snippet_tab=Docker) on how to host, and add a `base_url` parameter to point to your own instance when specifying `ChatNVIDIA`.

 ### NVIDIA API KEY
 You will need an NVIDIA API KEY to call NVIDIA AI Endpoints.  You can use different model API endpoints with the same API key, so even if you change the LLM specification in `ChatNVIDIA(model=llm_model)` you can still use the same API KEY.
