Creating a support chat bot for my business

API
1

Hello

I am trying to create a kind of Support Bot to answer my clients about specific technical details about WordPress plugins that I sell.

The goal is that the /completitions api would be feeded a prompt which could be something general like a CSS styling change which the davinci engine knows without any specific data about my business, but the customer might ask something specific for which I have about a data set of 3000 questions and answers ( prompts / completions ? input / output ? ) on which the bot can feed on. - exactly like this awesome example here

I am a web developer and I don’t have experience with AI. I am just scratching the surface trying to put this bot together learning concepts like Machine Learning, Training Data, Validation Set, Plotting, Neural Network. So bear with me cause it’s a lot to grasp :pleading_face:

So first of all, I did a lot of documenting and getting an API key from OPENAI is certainly the first step.

Then I told ChatGPT my story and what I tried to achieve, I asked him to write in PHP preferably , but it always ends up hallucinating so could not really use anything he generated without adjusting. And the further I asked him about specifics, the further he hallucinated.

So I read a lot of documentation and extrapolating with what I got from ChatGPT I think there are 3 ways to achieve this:

  • fine tuned model
  • uploading a training set and a validation set
  • embeddings api ( which the example that I linked uses )

Understanding that most examples are on Python, I started mlq.ai/gpt-3-fine-tuning-key-concepts/ tutorial - then I prepared with fine-tunes.prepare DATA_UNDER_COMMENT into the json by line to be categorised in prompt and completions

Then, I used openai api fine_tunes.create -t to create my fine-tune

and now I have my fine-tune created and I run

openai.Completion.create(
    model=FINE_TUNED_MODEL,
    prompt=YOUR_PROMPT)

this looked like the way to go, but even if put a basic question that was actually in the JSONL, it’s like the engine forgot to talk and outputs random characters

so I tried another approach from the cookbook which seems pretty great - following this which seems exactly like what I want to achieve .

Blockquote The GPT models have picked up a lot of general knowledge in training, but we often need to ingest and use a large library of more specific information.

I tried to use the code there, but with my CSV hosted online I got a 406 response when trying to load
Then I stored the CSV locally, and it complained that a column ( tokens ) was not available for converting to int ( 10 )
Then from what I could understand I switched from using load_embeddings to compute_doc_embeddings because it says from the documentation that they already have the embedding generated for that CSV

I did that, but now it asks for a json instated of CSV

Of course, I am able to provide my data in any format, so when I tried to load my data it says that the token limit of 8000 is exceeded for this request

I now try to input a small json here - under a comment

and try to run a prompt. And, kind of amazing, after hours of work, it seems to work. I provide a question from the data, but under a different structure and it replies to me correctly, using a different wording than the one from the json data.

he could have not known this from the general knowledge.

so this is what I want to achieve, but my data set is much larger.

I need help to understand if my approach is correct . And if Embedding is the way to go , how to feed data into OpenAI and reference that embeddings set when doing api calls to completions. Ideally I would have those embeddings stored somehow with the possibility to add to them. Just like I have fine tune sets or files under my API account.

Welcome to the forum.

If you search, you’ll find a lot of gems regarding what you’re asking.

Sounds like you’re on the right track. Good luck!

It seems like you might need some help with the infrastructure necessary to integrate Embeddings and GPT. LlamaIndex/GPT Index is an open-source project you might find helpful in that case.

I have a similar question, I’m trying to use llama index in a commercial app. I’m using it to create an index object from my custom data and query it. I’m assuming chatgpt is actually creating the embeddings for the index, and I have a paid openai account who’s api key I provide to make the code work. I’m wondering if llama index can be used in commercial app like this. my example function is below:

def index_response(api_key,text_path,query):

    # api key you generate in your openai account

    import os

    # add your openai api key here
    os.environ['OPENAI_API_KEY'] = api_key

    # Load you data into 'Documents' a custom type by LlamaIndex
    from llama_index import SimpleDirectoryReader

    documents = SimpleDirectoryReader(text_path).load_data()

    from llama_index import GPTVectorStoreIndex

    index = GPTVectorStoreIndex.from_documents(documents)

    query_engine = index.as_query_engine()
    response = query_engine.query(query)

    return response.response
