It is small enough for deployment on the phone and excels due to its dataset, composed of heavily filtered web data and synthetic data, ensuring robustness, safety, and adaptability to chat formats. This showcases the potential of small yet powerful models in both specialized and broader applications.
Small Language Models vs Large Language Models
We frequently encounter questions like: what is the advantage of a small language model (SLM) over a large language model (LLM)? or
In which scenario might a small language model (SLM) be a more appropriate solution than a large language model (LLM)?
Large language models 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 may face LLM security concerns, such as the risk of exposing sensitive data through APIs. In contrast, SLMs, which are 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. Additionally, combining both RAG and fine-tuning can further enhance the accuracy and relevance of outputs.
