Does LLM Size Matter? How Many Billions of Parameters do you REALLY Need?

The podcast explores the utility of large language models (LLMs) of varying sizes when run locally on personal computers, questioning whether smaller models can still yield valuable results without relying on cloud-based services. It highlights that while larger models generally perform better, the technique of quantization, which reduces the precision of the model's parameters, allows even 70 billion parameter models to run on PCs with sufficient RAM. The host tests open-source models from Meta, Google, Microsoft, IBM, and LG, using different parameter sizes and quantization levels to assess their performance on tasks ranging from sentiment analysis to complex reasoning. The findings suggest that 4-bit quantization provides a good balance between model size and functionality, and specialist LLMs like the Quen Coder can be highly effective for specific tasks even with fewer parameters.
