Testing Model

Prompt gen model can be used to generate prompts from provided chunks, which can further be used to create domain specific dataset for any base LLMs.

In this test model Mistral-7B-v0.1 is used as base model to finetune as prompt-gen model, fintuned version mimic gpt-3.5 in generating prompts from text chunks.

These type of model can be helpful in generating dataset at low cost compared to gpt and large amount of datapoint for fintenuning any llm for domain specific tasks.
