A r/LocalLLaMA post (1,021 upvotes, 59 comments) documents running Andrej Karpathy's 260K TinyStories model (Llama 2 architecture, ~1MB checkpoint) on a stock 1998 iMac G3 Rev B — 233MHz PowerPC 750 processor, 32MB RAM, Mac OS 8.5, with no upgrades. The project demonstrates the absolute minimum hardware floor for LLM inference and showcases how far model compression has come.
