Ben Santora continues his exploration of small language models (SLMs) with a focus on running them locally using CPU-only mode. This approach is particularly relevant for those who lack access to expensive NVIDIA GPUs. Santora, an engineering technician, details his journey in a series of articles aimed at simplifying the process of testing SLMs on older, less powerful machines. His setup includes an HP ENVY 17m with an Intel Core i7-1165G7 processor, 12 GiB of RAM, and an integrated Intel Iris Xe GPU, running a light Linux OS to optimize performance.

The author emphasizes the advantages of using a minimalist Linux environment, such as Crunchbang Plus Plus, which reduces background CPU and RAM usage. This setup allows older machines to function as dedicated AI research stations, capable of running quantized smaller models. Santora's goal is to pass on his findings to others who might want to explore these models on their devices, demonstrating that even underpowered machines can effectively run AI models.

Santora introduces a series of logic puzzles to test the capabilities of SLMs, including a 'Poison Pill' puzzle designed to expose the models' tendency to override logic in favor of being helpful. He highlights that these puzzles can reveal important insights about the models' behavior, such as their handling of contradictions and their inclination towards 'hallucination' to produce a result. This approach provides a benchmark for testing SLMs and understanding their limitations and strengths.

Looking ahead, Santora plans to continue experimenting with various SLMs and devising new tests to push their limits. He encourages others to explore these models on spare PCs or even Raspberry Pis, noting that the accessibility of SLMs means that expensive hardware is no longer a necessity for AI exploration. This democratization of AI tools is set to empower a wider range of enthusiasts and researchers in the field.
