What are LLMs in AI? 

“Under the hood, LLMs use deep learning techniques to build a complex statistical model.”

“They analyze relationships between words in the training data to learn the patterns of human language.”

The LLM Revolution: How AI-Language Models Are Transforming Lives

Before we get into the nitty gritty, it is essential to understand the meaning of large language models. How do LLMs work? Let us find out!!

What is a custom large language model? 

Who wouldn’t want human-like problem-solving abilities from a machine? Custom LLMs receive industry-specific training according to instructions, text, or code. Therefore, a custom LLM converts the abilities of an LLM and tailors it to a specific task.

As a result, these large language models become more accurate.

According to data from Johnsnowlabs, “Technical leaders value state-of-the-art accuracy (48%), no data sharing with software vendors (44%), and the ability to train their own models (42%) when evaluating machine learning, NLP, or computer vision solutions.”

Accuracy is one of the most prominent qualities of deploying custom large language models. Custom LLMs are the product of fine-tuning large language models.

What would be the reason behind this? Organizations aim to provide a better experience for their customers. Therefore, custom large language models can fill the gap. 

Customization and finetuning LLMs 

Once you teach your LLM the basics, the next step is to fine-tune it. The pretraining process involves large amounts of data. Finetuning LLMs is all about optimizing the model according to your needs. 

Despite the impressive ability of LLMs to generate text in various contexts, they require fine-tuning to perform specific tasks or understand particular domains more accurately.” 

“Fine-tuning trains the LLM on task-specific or domain-specific data, thereby enhancing its performance in those areas.”

Archana Vaidheeswaran, data product manager, A Beginner’s Guide to Fine-Tuning Large Language Models

Below are some steps that come under the process of finetuning large language models

  • Identify your organization’s goals and requirements
  • Adapt the AI models to your company’s delivery methods such as videos, textual content, podcasts, etc. 
  • Ensure that employees are a part of the learning stage
  • This is a must – the smooth integration of custom LLMs with existing systems such as performance management, customer email correspondence, reports, data handling, etc. 
  • Last but not least- set up analytics to check functionalities and progress of LLM performance.
