Custom LLM: Your Data, Your Needs

Before training the LLM, it is essential to identify your data source(s) and to preprocess and clean the dataset. This may involve removing irrelevant or duplicate data, eliminating any bias, tokenizing the text into smaller units, and formatting the data in a way that is compatible with the chosen LLM framework. This step ensures that the LLM receives high-quality input during the training process.

How to customize LLM models?

  1. Prompt engineering to extract the most informative responses from chatbots.
  2. Hyperparameter tuning to manipulate the model's cognitive processes.
  3. Retrieval Augmented Generation (RAG) to expand LLMs' proficiency in specific subjects.
  4. Agents to construct domain-specialized models.

You have to upload your documents to S3, create a “Knowledge Base” then sync your documents into a vector database like OpenSearch or PineCone. I used this simple example to teach about RAG, the importance of the system prompt and prompt injection. The notebook folder has a few more examples, local models can even do natural language SQL querying now. A common technique called in-context learning can help you get around this.

If you’re not well-versed in these settings, don’t worry; LLM Studio offers best practices to guide you. Additionally, you can use GPT from OpenAI as a metric to evaluate your model’s performance, though alternative metrics like BLEU are available if you prefer not to use external APIs. H2O, a prominent player in the machine learning world, has developed a robust ecosystem for LLMs. Their tools and frameworks facilitate LLM training without the need for extensive coding expertise.

Finding the right pre-trained model

Embedding and chunking large amounts of documents is expensive though, in both compute and storage. Do any of you have experience using a small local model just for extracting keywords from messages which you then use for the retrieval? And then feed the search result and your prompt into OpenAI or whatever as normal. I think Pinecone is a cheaper database for hobby and small business projects, though I haven’t looked into it. Developing it to realise when there are too many results and to prompt the user to clarify or be more specific would help. With a large amount of data, a large amount of data can be “relevant” with a loose query.

Custom LLM: Your Data, Your Needs

I have never heard of anyone successfully using that for a private document knowledgebase though. I think the issue is that you need a LOT of data and it needs to repeat concepts or any facts you need to learn many, many times in different supporting ways. Because the model doesn’t have relevant company data, the output generated by the first prompt will be too generic to be useful.

Locusive’s API

The platform uses LLMs to generate personalized marketing campaigns, qualify leads, and close deals. IBM uses custom LLMs to power its Watson cognitive computing platform. Watson is used in a variety of industries, including healthcare, finance, and customer service.

Can I design my own AI?

AI is becoming increasingly accessible to individuals. With the right tools and some know-how, you can create a personal AI assistant specialized for your needs. Here are five steps that will help you build your own personal AI.

This is particularly problematic when the private data is from a niche domain or industry. The training process involves feeding the dataset to the LLM model and adjusting its internal parameters to minimize Custom Data, Your Needs the difference between the generated output and the desired output. The training process can take several hours or even days, depending on the size of the dataset and the complexity of the LLM model.

Prerequisites of having a custom LLM application

Out of the box, the ggml-gpt4all-j-v1.3-groovy model responds strangely, giving very abrupt, one-word-type answers. Even on an instruction-tuned LLM, you still need good prompt templates for it to work well 😄. It’s also fully licensed for commercial use, so you can integrate it into a commercial product without worries. This is unlike other models, such as those based on Meta’s Llama, which are restricted to non-commercial, research use only. There are a lot of open source LLMs we can use to create private chatbots. Fortunately for us, there is a lot of activity in the world of training open source LLMs for people to use.
