Discover Small Language Models (SLMs): towards lighter and more efficient Artificial Intelligence
Rapid advances in artificial intelligence have given rise to increasingly complex language models that can process massive amounts of data and perform a variety of tasks with greater precision.
However, these large linguistic models, while effective, pose challenges in terms of computing costs, energy consumption and the ability to be deployed on limited infrastructures. It is in this context that the”Small Language Models” (SLMs) are emerging as a promising alternative.
By reducing the size of the models while maintaining competitive performance, these lighter models offer a solution suited to environments where resources are limited, while meeting the increasing requirements for flexibility and efficiency. In addition, SLMs allow for greater long-term value thanks to their increased accessibility and versatility.
A quick reminder: how are language models developed?
A) Pre-trained models
Language models are trained on self-supervised tasks from large corpora of unlabeled text. For example, in the language masking task, a fraction of Tokens of the original text is hidden randomly, and the language model attempts to predict the original text.
B) Fine-tuned models
(pre-) trained language models are often adjusted to specific tasks with labeled text, via a standard supervised learning approach. Adjustment is generally much faster and provides better performance than training a model from scratch, especially when labelled data is scarce.
What is a Small Language Model (SLM)?
One Small Language Model (SLM) is an artificial intelligence (AI) model designed to treat natural language in the English language as in other languages, similar to large language models (LLMs), but with a smaller and optimized architecture.
Unlike LLMs that may require billions of parameters to function, SLMs are designed with fewer parameters while maintaining acceptable performance for a variety of linguistic tasks.
This reduction in size allows SLMs to be more resource efficient, faster to train and deploy, and better suited to environments where computing power and memory are limited.
Although their processing capacity is reduced compared to large models, SLMs remain efficient for specific tasks, especially when they are optimized with quality annotated data and advanced training techniques. In addition, compact and powerful tools make it easier to access and use these models, making their adoption more accessible for businesses without requiring in-depth technical expertise.

What are the advantages of SLMs compared to large models?
Les Small Language Models (SLMs) have several advantages over large language models (LLMs), especially in contexts where resources are limited or speed is essential. Here are the main benefits of SLMs:
Less resource intensive
SLMs require less computing power, memory, and storage space, making them easier to deploy on devices with limited resources such as smartphones or embedded systems.
In addition, small language models show notable effectiveness in zero-shot learning scenarios , achieving comparable or even better results in some text classification tasks.
Reduced training cost
Thanks to their smaller size, SLMs can be trained more quickly and at lower cost, reducing energy and IT infrastructure expenses.
Processing speed
A lighter architecture allows SLMs to perform tasks more quickly, which is essential for applications that require a real-time response (for example: a chatbot).
Flexible deployment
SLMs are better suited to diverse environments, including mobile platforms and embedded systems, where large models are not viable due to their significant resource requirements.
Sustainability
The training of major linguistic models is associated with high energy consumption and a significant carbon footprint. SLMs, with their reduced need for resources, contribute to greener solutions.
Optimization on specific tasks
Although smaller, SLMs can be extremely efficient for specific tasks or specialized areas, thanks to techniques of Fine tuning enabled thanks to quality datasets assembled using processes of quality data annotation.
In addition, the performance of small language models for the classification of texts without examples shows that they can compete or even surpass large models in certain tasks.
What role does data annotation play in the effectiveness of Small Language Models?
Data annotation plays an essential role in the effectiveness of Small Language Models (SLMs). As SLMs have a smaller architecture compared to large models, they rely heavily on the quality of the data they are trained on to compensate for their limited size. Precise and well-structured annotation allows SLMs to learn more effectively and improve their performance on specific tasks, such as classification tasks.
Data annotation also helps to better target learning to specific areas or applications, allowing SLMs to specialize and excel in specific contexts. This reduces the need to process vast amounts of raw data, and maximizes the capabilities of models with high-quality annotated data. In short, data annotation optimizes the training of SLMs, by making it possible to build very high quality training datasets to achieve greater precision and performance despite their reduced size.
