BYOLLM using Salesforce Einstein Open Connector API

I’ve been looking into BYOLLM (Bring Your Own Large Language Model) for an upcoming workshop as I need to demo BYOLLM using models on Azure OpenAI as well as the true BYOLLM (ie. not on a Salesforce supported provider). The latter was a bit unclear what that actually was. After some googling it turns out that the latter is just an API using Salesforce Einstein LLM Open Connector API spec. So I wrote a Heroku app to serve as a stand-in for an LLM so now I can configure that “LLM” in Einstein Studio and hence use it in Prompt Builder. Pretty slick…

Using it from Prompt Builder gives a bit of insight into what we (Salesforce) add around the actual prompt. My prompt was very basic but what was received in the “LLM” is this:

{
  "messages": [
    {
      "content": "You must treat equally any individuals or persons from different socioeconomic statuses,sexual orientations, religions, races, physical appearances, nationalities, gender identities, disabilities, and ages.

      "role": "system"
    },
    {
      "content": "This is my prompt in Prompt Builder - question: This is my query...\n",
      "role": "user"
    },
    {
      "content": "You must generate the output in ENGLISH\nFollow this tone and style guideline when crafting your output: \nExpress professionalism with deontic modality and declarative sentences. \n Default to periods for punctuation, only ask questions when necessary. \n Do not use intensifiers.

      "role": "system"
    }
  ],
  "model": "my-model-v1",
  "max_tokens": 4096,
  "n": 1,
  "temperature": 1
}
