Build an LLM Application with Dataiku, Databricks, and LangChain

The responses also tended to go off on a tangent, which the tweaking of the prompt helped with also. Also, the answer sometimes seemed technical and did not feel like a natural conversation. I thought the LLM would respond better out of the box, but some prompt engineering is required to overcome some of these quirks. It uses a LangChain application on our local machine and uses our own privately hosted LLM in the cloud. And if we see our applications need more resources, we can scale them on their own, which would be cheaper, of course. If we check out the GPT4All-J-v1.0 model on hugging face, it mentions it has been finetuned on GPT-J.

However, there are platforms available today that make it much easier to combine your own data with an LLM and build an application to solve custom challenges. They let you access any LLM provider, create applications and workflows using either a visual interface or coding, and securely deploy them for use. You can iterate rapidly, make the most of various LLMs, connect to your databases and systems, and build in custom business logic and prompts securely. Data experts can develop use cases within a few hours for business teams who can in turn provide feedback to improve the quality over time. As a cherry on top, these large language models can be fine-tuned on your custom dataset for domain-specific tasks.

Especially if we want close to real-time data, the effort required to keep a LLM up to date is simply impractical. Finally, RAG provides a relatively simple and easy way to create a custom GPT instance. It does this without prior machine learning experience and is a good starting point when creating a custom AI tool. Casting too wide a net could also degrade rather than improve performance on the tasks you care about most.

Custom and general Language Models vary notably, impacting their usability and scalability. When comparing the computing needs for training and inference, these differences become evident, offering valuable insights into model selection. Research study at Stanford explores LLM’s capabilities in applying tax law. The findings indicate that LLMs, particularly when combined with prompting enhancements and the correct legal texts, can perform at high levels of accuracy.

Customizing LLMs is challenging but achievable

The future of AI-driven content generation and interaction is here, and it’s exciting to be part of this transformative journey. Then, you take all of your documents and divide them into meaningful chunks, ie by paragraph or something. An embedding model is another type (not an llm) that generates vectors for strings of text often based on how similar the words are in _meaning_. Ie if I generate embeddings for the phrase “I have a dog” it might (simplified) be a vector like [0.1,0.2,0.3,0.4].

AI is already becoming more pervasive within the enterprise, and the first-mover advantage is real. Data lineage is also important; businesses should be able to track who is using what information. Not knowing where files are located and what they are being used for could expose a company to heavy fines, and improper access could jeopardize sensitive information, exposing the business to cyberattacks. Despite this momentum, many companies are still unsure exactly how LLMs, AI, and machine learning can be used within their own organization. Privacy and security concerns compound this uncertainty, as a breach or hack could result in significant financial or reputational fall-out and put the organization in the watchful eye of regulators.

That being said, feel free to play around with some of these other models. How we will deploy our GPT4All model and connect to it from our application would probably be similar for any of these. Otherwise, the chatbot tended to go off on tangents and long rants about things only semi-related to our original question. This would get tedious if we needed to pass in the prompt every time we wanted to ask a question.

To solve this problem, we can augment our LLMs with our own custom documents. In this article, I will show you a framework to give context to ChatGPT or GPT-4 (or any other LLM) with your own data by using document embeddings. The second key challenge in retrieval augmented generation is writing a system message that correctly answers queries. Notably, the system message needs to prevent the LLM from hallucinating incorrect information while also allowing it some leeway in the LLM’s responses. First, you need to choose which sources of textual data you want to use.

You can just tell us your preferences while getting a demo if you would prefer a private cloud or on premise deployment. Finetuning works when the data is small(~50K tokens) and you want to teach the model specific patterns. You cannot teach a model a new knowledge Custom Data, Your Needs domain by using Finetuning no matter what the model is. With you host the model in your cloud, you control access, information, update knowledge all at your comfort. We can structure the prompt to provide instructions on how our LLM should respond to our question.

ChatGPT has successfully captured the public’s attention with its wide-ranging language capability. Shortly after its launch, the AI chatbot performs exceptionally well in numerous linguistic tasks, including writing articles, poems, codes, and lyrics. Built upon the Generative Pre-training Transformer (GPT) architecture, ChatGPT provides a glimpse of what large language models (LLMs) are capable of, particularly when repurposed for industry use cases. In the above example, we demonstrated how to fine-tune a GPT-based model on your private data. Managing the model, fine-tuning, running different experiments with different datasets, deploying the fine tuned model, and having a working solution, isn’t a simple process. Using Qwak, you can manage this process, get the resources that you need, and have a working fine-tuned model in just a few hours.

Open-source models

To run the inference, I’ll need to send the data to the model in the right format.

I would have expected the LLM to perform a bit better, but it seems it needs some tweaking to get it working well. We want it to act more like a Q&A chatbot, and we need to give it a better prompt. At first, we see it loads up the LLM from our model file and then proceeds to give us an answer to our question. You are interacting with a local LLM, all on your computer, and the exchange of data is totally private. My computer is an Intel Mac with 32 GB of RAM, and the speed was pretty decent, though my computer fans were definitely going onto high-speed mode 🙂. They have a pretty nice website where you can download their UI application for Mac, Windows, or Ubuntu.
