Developer creates 'conversational AI' that can run in 64kb of RAM on 1976 Zilog Z80 CPU-powered system — features a tiny chatbot and a 20-question guessing game

Developer HarryR has created a "conversational AI" that can run on a 1976 Zilog Z80 CPU-powered system with just 64kb of RAM. The AI project includes a tiny chatbot and a 20-question guessing game, showcasing the capabilities of the vintage microprocessor. The AI, named Z80-μLM, uses quantization-aware training and autoregressive generation to produce character-by-character responses. While not passing the Turing test, the AI project demonstrates how small an AI can be while still having a "personality." The chatbot's responses are short and sometimes vague, creating a unique mode of interaction for users.
