SLM vs LLM: What is the difference between them? Which Model Has Greater Potential for Revolutionising Business AI Solutions?

The evolution in the field of information and technology, especially after the shift towards Artificial Intelligence and particularly in the domain of Natural Language Processing (NLP), has done wonders. These advancements introduced in NLP aim to generate a communication mechanism that is intelligent enough to communicate like humans.

This raises the question: What is the driving force behind NLP that enables human-like communication? This human-like communication is made possible by integrating the Small Language Model (SLM) or the Large Language Model (LLM) behind NLP. The choice between either of them to carry out your desired task depends upon the requirements of the task that is expected to be achieved by businesses.

So through our article on SLM vs LLM, we aim to help you understand that either the Small Language Model (SLM) or Large Language Model (LLM) has the better ability to provide the most efficient solution for your particular AI-driven business idea.

What is Small Language Model (SLM)?

Small Language Model (SLM) is a methodology to implement Artificial Intelligence that possesses a relatively compact architecture that enables it to require fewer resources for computations. SLM is engineered to execute specific language tasks efficiently, by utilizing the minimum resources that differentiate them from their Large Language Model (LLM) counterparts

SLM Architecture

SLM incorporates fewer parameters, which inferences that the training and deploying process for this is much simpler and prompt. They offer excellent performance for specialized tasks rather than general purpose language understanding tasks; enhancing its significance for executing your choice tasks within the limited provided resources.

Categories of SLM; With Its Practical Implementation in Industry

To improve your understanding this Small Language Model can be categorized into further types based on its architecture, purpose, and performance. So, Let's delve further into SLM by discussing its types, and the specialized functionality it offers to get the assigned tasks done.

Rule-Based Models:

As the name suggests this model works on predefined linguistic rules for language processing, rather than learning from data they tend to utilize clear-cut programming to understand the context of the text and generate a text accordingly.

Example: Initially introduced chatbots used to exercise the if-else rule to counter user inputs. Like: ELIZA at MIT, and Grammar Checkers in Microsoft Word.

Statistical Models:

The statistical model type of SLM used probabilistic methodologies to predict the next word in the sequence, to understand or generate a text. It comprises the the n-gram concept for predicting the next word in sequencing, which actually works by making n the number of words being considered to generate the next word.

Example: Using bigram where (n=2) or trigram where (n=3) model for text prediction. Like: Google Search (2000s), and T9 Predictive Text in Nokia Phones.

Neural Network Models:

The neural network architecture type of SLM, incorporates feedforward or Recurrent Neural Networks (RNN) for language processing tasks, which actually works by learning from dataset to improve their performance over time.

Example: LSTM( Long Short Term Memory) are specialised to predict the word considering a number of preceding words present in the sequence. Like: Phi-3, and MiniCPM-Llama3-V 2.5.

Task-Specific Models:

The task specific model type of SLM, aims to provide a tailored way to execute your desired task that could be: text recognition or summarization. This has been possible for them to achieve since they are fine tuned on specific dataset to perform these specialized tasks.

Example: Sentiment analysis tasks for classifying feedback as positive or negative uses this. Like: DeepSeek-Coder-V2, and Gemma 2.

As LLMs are trained on large datasets this makes them expensive, a deployment of such modals requires significantly heavy computational resources, for it to provide the desired output.

• Bias and Ethical Concerns:

LLMs have the tendency to unintentionally learn and tweak their present biases in the training data, which involves ethical and reliability concerns when you are considering deploying it for sensitive applications.

• Limited Understanding:

Although the output generated from LLM might apparently look Intelligent, sometimes they may lack comprehension, as the function is based on pattern of data rather than trying to understand the exact context being intended to deliver, which can possibly lead to misleading outputs.

• Dependence on Data Quality:

LLMs are highly data dependent, so misleading or poor quality data can severely result in delivering undesired outputs.

• Inflexibility to Changes:

One of the concerning limitations of LLMs is that once they are trained on a specific data they cannot adapt well to the new data, so in order to make it updated they have to be retrained on the new dataset, which consumes time and effort.

SLM or LLM: Which one is better for your business?

Whether it's SLM or LLM both have the capability to offer great functionality, but both also offer best performance for some specific use cases. If you are looking to integrate AI for some dedicated small scale tasks for which you require a more focused rapid approach to compute your desired output without it getting computationally expensive, then it's recommended to you to utilize SLM architecture for your business idea.

However, if your business idea demands such an architecture that delivers high quality, and has the ability to adapt to new approaches by fine tuning, and also provide scalability then it's ideal for you to implement LLMs for achieving your expected results. As LLMs have the ability to ensure these qualities, which makes it computationally expensive too.

Future of SLM and LLM in Business World
