TL; DR: From my personal experiments (on an 8-year-old, i5 laptop with 16 GB RAM), locally hosted LLMs are extremely useful for many tasks that do not require much model-captured knowledge.

The era of relying solely on large language models (LLMs) for all-encompassing knowledge is evolving. As technology advances, the focus shifts towards more specialized and integrated systems. These systems combine the strengths of LLMs with real-time data access, domain-specific expertise, and interactive capabilities. This evolution aims to provide more accurate, context-aware, and up-to-date information, saving us time and addressing the limitations of static model knowledge.
I have started to realize that LLMs are more useful as language assistants who can summarize documents, write discharge summaries, and find relevant information from a patient’s medical record. The last one still has several unsolved limitations, and reliable diagnostic (or other) decision-making is still in the (distant?) future. In short, LLMs are becoming increasingly useful in healthcare as time-saving tools, but they are unlikely to replace us doctors as decision-makers soon. That raises an important question; Do locally hosted LLMs (or even the smaller models) have a role to play? I believe they do!
Locally hosted large language models (LLMs) offer several key benefits. First, they provide enhanced data privacy and security, as all data remains on your local infrastructure, reducing the risk of breaches and unauthorized access. Second, they allow for greater customization and control over the hardware, software, and data used, enabling more tailored solutions. Additionally, locally hosted LLMs can operate offline, making them valuable in areas with unreliable internet access. Finally, they can reduce latency and potentially lower costs if you already have the necessary hardware. These advantages make locally hosted LLMs an attractive option for many users.
The accessibility and ease of use offered by modern, user-friendly platforms like OLLAMA are significantly lowering the barriers for individuals seeking technical expertise in self-hosting large language models (LLMs). The availability of a range of open-source models on Hugging Face lowers the barrier even further.
I have been doing some personal experiments with Ollama (on docker), Microsoft’s phi3: mini (language model) and all-minilm (embedding model), and I must say I am pleasantly surprised by the results! I have been using an 8-year-old, i5 laptop with 16 GB RAM. I have been using it as part of a project for democratizing Gen AI in healthcare, especially for resource-deprived areas (more about it here), and it does a decent job of vectorizing health records and answering questions based on RAG. I also made a helpful personal writing assistant that is RAG-based. I am curious to know if anybody else in my network is doing similar experiments with locally hosted LLMs on personal hardware.
