Thanks to training on extremely large amounts of data supported by extensive computational infrastructure, LLMs can demonstrate impressive performance on a variety of tasks. However, these very same reasons became the main obstacles for individual users benefiting from LLMs. This is threatening to deepen the digital divide in the society. Quantization is aimed at making LLMs more accessible on consumer devices by trading off performance for a lesser computational demand. In this study, we evaluated the feasibility of running code LLMs with 7 billion parameters on consumer devices. The quantized code LLMs were evaluated using Lua programming tasks as e benchmark and with respect to several metrics including pass@1 rate, inference time, error types, and lines of code generated. The quantized code LLMs were also compared to non-quantized code LLMs with lower parameter numbers. The overall results suggest that code LLMs quantized at 4-bit integer precision can be comfortably run on an average CPU-only consumer laptop while maintaining good performance relative to other quantized and non-quantized code LLMs. The 4-bit quantized models also outperformed the non-quantized models with lower parameter numbers. However, the study also revealed that the exact effects of quantization are not homogeneous among the five tested models. The performance of a quantized model may also be a subject of the model architecture, pre-trained dataset, training procedure, and follow-up fine-tuning. Therefore, a more in-depth study is necessary to explore how these factors and quantization interact. Furthermore, besides the four general categories, the exact nature of errors in code generated by the code LLMs was not explored in this study. Such understanding can give a greater insight into the effects of quantization on code generation and how to mitigate respective performance degradation. This also needs to be addressed in a follow-up study. Finally, using Lua, a low-resource language, as a benchmark further emphasizes the need to improve LLMs aimed at precision tasks such as code generation. This highlights the need for enabling consumers to not only quantize but also fine-tune models for specific tasks. Furthermore, accessibility of fine-tuning is not only an algorithmic problem but also the issue of data availability. Therefore, the democratization of LLMs also involves the democratization of training data, which also needs to be addressed in future work.
