Nvidia Dynamo Integration - Helicone OSS LLM Observability

Warning

This integration method is maintained but no longer actively developed. For the best experience and latest features, use our new AI Gateway with unified API access to 100+ models.

Use Nvidia Dynamo or other OpenAI-compatible Nvidia inference providers with Helicone by routing through our gateway with custom headers.

How to Integrate#

Create an account and generate an API key

Log into Helicone or create an account. Once you have an account, you can generate an API key here.

Set up your Helicone API key in your .env file

HELICONE_API_KEY=<your-helicone-api-key>NVIDIA_API_KEY=<your-nvidia-api-key>

Modify the base URL path

curl -X POST https://gateway.helicone.ai/v1/chat/completions \  -H "Content-Type: application/json" \  -H "Authorization: Bearer $NVIDIA_API_KEY" \  -H "Helicone-Auth: Bearer $HELICONE_API_KEY" \  -H "Helicone-Target-Url: https://your-dynamo-endpoint.com" \  -d '{    "model": "your-model-name",    "messages": [      {        "role": "user",        "content": "Hello, how are you?"      }    ],    "max_tokens": 1024,    "temperature": 0.7  }'

Verify your requests in Helicone

With the above setup, any calls to Dynamo will automatically be logged and monitored by Helicone. Review them in your Helicone dashboard.
