In an era of language models, small language models (SLMs) represent a pivotal advancement in natural language processing, offering a compact yet powerful solution to various linguistic tasks.
Most companies are into developing SLMs for their accessibility, computational efficiency, and adaptability, making them ideal for deployment in edge devices and cloud environments, fostering a new era of natural and intuitive human-computer interaction.
List of Best Small Language Models
At Ignite, Microsoft CEO Satya Nadella, famously said, “Microsoft loves SLMs”, which was quite a kickstart for the other SLMs too. We have compiled a list of the best small language models.
Llama 2 7B
Llama 2, Meta AI’s second-generation open-source large language model, released in July, has an impressive 34 billion parameters, and the smaller 7 billion model was made specially for research purposes. It significantly enhances the model’s performance, efficiency, and accessibility compared to its predecessor.
With demonstrated text generation, translation, and code generation improvements, Llama 2 caters to a wide array of NLP tasks. The model’s multilingual capabilities and availability of fine-tuned versions for specific tasks, such as Code Llama, broaden its applications from machine translation to chatbots and content creation.
Many of the current open-source models are built on top of the Llama family of models.
Phi2 and Orca
