Helicone integration

Helicone is an open source observability platform that proxies your LLM requests and provides key insights into your usage, spend, latency and more.

To reference prompts in Helicone:

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

  2. Set the HELICONE_API_KEY and environment variables as desired.

  3. Use the helicone:// prefix for your prompts, followed by the Helicone prompt id and version. For example:

    prompts:
      - 'helicone://my-cool-prompt:5.2'

    providers:
      - openai:gpt-4o-mini

    tests:
      - vars:
          # ...

Variables from your promptfoo test cases will be automatically plugged into the Helicone prompt as variables.
