Update for conversation support #4

This one is going to be much harder than the others, in particular these two:

The problem is that PaLM and MPT-30B both have a single, set format for conversation prompts.

The gpt4all models don't have a single format. The format is partially described in https://gpt4all.io/models/models.json - at least some of the models define a promptTemplate (and sometimes also a systemPrompt) which tend to look like one of these:

ggml-model-gpt4all-falcon-q4_0.bin:

### Instruction:
%1
### Response:

ggml-mpt-7b-chat.bin:

<|im_start|>user
%1<|im_end|><|im_start|>assistant

Some of them don't offer a hint like this at all.

https://lite.datasette.io/?json=https://raw.githubusercontent.com/nomic-ai/gpt4all/main/gpt4all-chat/metadata/models.json#/data/models?_facet=promptTemplate reveals that only 6 out of the 17 models have a promptTemplate:

For prompts like "### User:\n%1\n### Response:\n" a conversation can be modeled by stacking them on top of each other, repeating it for each one and gluing the response on at the end.

"<|im_start|>user\n%1<|im_end|><|im_start|>assistant\n" is a bit more complicated, since it needs a <|im_end|> added at the end to complete the assistant part of the prompt.

But what should I do for the 11 models that don't define a promptTemplate at all?

I'm going to do the simplest thing possible - "user text\nassistant text\nuser text 2\nassistant text 2\n" - that will at least get something working, and for the majority of cases where they are used outside of conversation --continue mode it won't matter at all.

Running Orca without the prompt template gives odd results:

[
  {
    "id": "01h53v44kqknwandv2j26mw710",
    "model": "orca-mini-3b",
    "prompt": "name a squirrel",
    "system": null,
    "prompt_json": null,
    "options_json": {},
    "response": ", and the other a bs.\nI'm not sure what to do with this information.",
    "response_json": null,

    "conversation_name": "name a squirrel",
    "conversation_model": "orca-mini-3b"
  }
]

The templates for that one are:

{
    "promptTemplate": "### User:\n%1\n### Response:\n",
    "systemPrompt": "### System:\nYou are an AI assistant that follows instruction extremely well. Help as much as you can.\n\n"

I found this method: https://github.com/nomic-ai/gpt4all/blob/e9d42fba358d52eda3c070889e08f1f508e9c8da/gpt4all-bindings/python/gpt4all/gpt4all.py#L253-L279

    def _format_chat_prompt_template(
        self, messages: List[Dict], default_prompt_header=True, default_prompt_footer=True
    ) -> str:
        """
        Helper method for building a prompt using template from list of messages.

        Args:
            messages:  List of dictionaries. Each dictionary should have a "role" key
                with value of "system", "assistant", or "user" and a "content" key with a
                string value. Messages are organized such that "system" messages are at top of prompt,
                and "user" and "assistant" messages are displayed in order. Assistant messages get formatted as
                "Response: {content}".

        Returns:
            Formatted prompt.
        """
        full_prompt = ""

        for message in messages:
            if message["role"] == "user":
                user_message = "### Human: \n" + message["content"] + "\n### Assistant:\n"
                full_prompt += user_message
            if message["role"] == "assistant":
                assistant_message = message["content"] + '\n'
                full_prompt += assistant_message

        return full_prompt

Which implies to me that the default prompt template if none is specified should be that.

I searched the gpt4all codebase and couldn't find any evidence of their Python library using the promptTemplate or systemPrompt values.

Maybe they're just used for this bit of the UI:

This seemed to work:

    "conversation_model": "orca-mini-3b"
  }
]

From:

llm -m orca-mini-3b 'name a squirrel'

I'm sorry, but I cannot answer that question as it does not make sense. Can you please provide more context or information to help me understand what you are asking?

llm -c 'Give me cute names for a squirrel'

Sure! Here are some cute squirrel names:

  1. Benny the Squirrel
  2. Thumper the Squirrel
  3. Hazel the Squirrel
  4. Daffy the Squirrel
  5. Slimer the Squirrel
  6. Wally the Squirrel
  7. Gus the Squirrel
  8. Babs the Squirrel
  9. Muffin the Squirrel
  10. Twister the Squirrel

It looks like the first one didn't get the system prompt though, maybe that's why it gave a bad answer.

Confirmed - fixing the system prompt bug for the first message got this:

llm -m orca-mini-3b 'name a squirrel'

Hey, I'm not sure if you meant to ask for a specific name of a squirrel or just a general one. Can you please clarify your question?

Trying the model that uses the weird tokens:
