What are Small Language Models?

Small Language Models (SLMs) represent a specialized subset within the broader domain of artificial intelligence, specifically tailored for Natural Language Processing (NLP). SLMs are Characterized by their compact architecture and less computational power. Small Language Models are engineered to efficiently perform specific language tasks, with a degree of efficiency and specificity that distinguishes them from their Large Language Model (LLM) counterparts.

Small vs Large Language Models (SLM vs LLM)

LLMs such as GPT-4 are transforming enterprises with their ability to automate complex tasks like customer service, delivering rapid and human-like responses that enhance user experiences. However, their broad training on diverse datasets from the internet can result in a lack of customization for specific enterprise needs. This generality may lead to gaps in handling industry-specific terminology and nuances, potentially decreasing the effectiveness of their responses.

On the contrary, SLMs are trained on a more focused dataset, tailored to the unique needs of individual enterprises. This approach minimizes inaccuracies and the risk of generating irrelevant or incorrect information, known as “hallucinations,” enhancing the relevance and accuracy of their outputs. Moreover, when fine-tuned for specific domains, SLMs achieve close language understanding to LLMs, demonstrating their capability in language understanding across various natural language processing tasks, which is crucial for applications requiring deep contextual comprehension.

Despite the advanced capabilities of LLMs, they pose challenges including potential biases, the production of factually incorrect outputs, and significant infrastructure costs. SLMs, in contrast, are more cost-effective and easier to manage, offering benefits like lower latency and adaptability that are critical for real-time applications such as chatbots.

Security also differentiates SLMs from open-source LLMs. Enterprises using LLMs may risk exposing sensitive data through APIs, whereas SLMs, often not open source, present a lower risk of data leakage.

Customization of SLMs requires data science expertise, with techniques such as LLM fine-tuning and Retrieval Augmented Generation (RAG) to enhance model performance. These methods make SLMs not only more relevant and accurate but also ensure they are specifically aligned with enterprise objectives.
