Large Language Model (LLM)

Large Language Model (LLM) refers to a class of AI models—often based on transformer architectures—that are trained on vast amounts of text data. These models typically contain hundreds of millions to billions of parameters, enabling them to perform tasks such as language translation, text generation, and context-aware question answering at a high level of fluency. Examples of LLMs include GPT-3.5, GPT-4, BERT, and LLaMA.

How an LLM Differs from an SLM

While “LLM” is a well-established term in AI research, “SLM” can refer to “Small Language Model,” “Specialized Language Model,” or another variant depending on context. In general, an SLM would be:

•Smaller in Size: SLMs often have fewer parameters and may be trained on more limited datasets, which reduces their resource requirements.

•Narrower in Scope: They tend to be optimized for specific tasks (e.g., answering questions in a specialized domain) rather than providing broad language capabilities.

•Lower Computational Footprint: Because of their smaller scale, SLMs typically require less computational power for both training and inference, making them more accessible for edge or on-device applications.

By contrast, LLMs aim for broad, flexible language understanding and generation, often at the cost of higher computational demands. They can handle a wide variety of tasks but may require extensive fine-tuning to match the domain-specific accuracy that a specialized (or smaller) model could achieve with fewer parameters.
