A software engineer has successfully run generative artificial intelligence (AI) on a 20-year-old PowerBook G4, showcasing the device's unexpected capabilities. The experiment demonstrates that it is possible to operate a modern large language model (LLM) on older hardware, specifically the 2005 PowerBook G4, which features 1 GB of RAM. However, the performance is not comparable to contemporary systems, as the processing speeds fall short of consumer expectations. This achievement highlights the potential of older technology when paired with advanced software.
