How to fine-tune OpenAI’s large language models (LLMs)

Large language models (LLMs) are a type of artificial intelligence (AI) that can generate and understand text. They are trained on massive amounts of text data, which allows them to learn the statistical regularities of language. LLMs can be used for a variety of tasks, including translation, writing different kinds of creative content and answering questions in an informative way.

LLMs are still under development, but they have the potential to revolutionize the way we interact with computers. There are several use cases of LLM. For example, LLMs could be used to create chatbots that can have more natural and engaging conversations with users. They could also be used to develop new educational tools that can help students learn more effectively.

One way to improve the performance of LLMs is to fine-tune them for specific datasets. Fine-tuning is the process of re-training a pre-trained model on a new dataset. This allows the model to learn the specific characteristics of a new dataset and improve its performance on tasks related to that dataset.

Processing text data with LLM

One notable use case of fine-tuning OpenAI’s language models is in the domain of customer support chatbots. Imagine a large e-commerce platform dealing with thousands of customer queries daily. By fine-tuning an LLM, the platform can create a chatbot capable of understanding customer inquiries, providing relevant product recommendations, and even solving common issues without human intervention. This not only enhances the customer experience by providing instant and accurate responses but also significantly reduces the workload of human support agents.

Consider a financial institution that needs to analyze vast amounts of textual data from various sources like customer reviews, financial reports, and news articles to predict market trends. Fine-tuning an LLM allows them to process this textual data efficiently. By understanding the context, sentiment, and trends within the data, the institution can make data-driven decisions, predict market movements, and develop effective investment strategies. This gives the institution a competitive edge in the volatile financial market.

How to fine-tune LLM for our use case

Steps to achieve fine-tuning:

Prepare training dataset

training_data = [
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": "User message 1."},
{"role": "assistant", "content": "Assistant response 1."},
# Add more training data as needed
]

Upload training data file to the OpenAI server

import OpenAI Set your OpenAI API key
openai.api_key = 'your-api-key'
file = openai.File.create(file=open("file_path", "rb"), purpose="fine-tune")

Create fine-tuned model with above generated file ID

create_args = {
"training_file": "File_ID_generated from above operation",
"model": "gpt-3.5-turbo",
"suffix" : "your_suffix"
}
response = openai.FineTuningJob.create(**create_args)

Use fine-tuned model

finalmessages=[
{"role": "system", "content": “System_content”},
{"role": "user", "content": “user_question”}
]
finalresponse = openai.ChatCompletion.create(model="gpt-3.5-turbo",temperature = 0.2, messages=finalmessages)
Response = finalresponse.choices[0].message.content
