An engineer named Arvind Sanjiv described how he managed to install a modern neural network on an old Brother AX-325 typewriter manufactured in the 90s. This allowed the machine to literally talk to a person. The project is called Ghostwriter and the software uses the GPT-3 language model on which the ChatGPT chatbot runs.

Sanjeev first disassembled the device, then added an Arduino board to it that allows pressing buttons. The design also uses Raspberry Pi, a network interface for the OpenAI GPT-3 API.

Additionally, the engineer added a small OLED screen and two arms. With their help, you can control some parameters of the chatbot – the level of creativity of the neural network and the length of the answers. To be compatible with AI, you simply insert a piece of paper into the machine and start printing.

Note that GPT-3 has been trained on millions of books and this neural network is quite capable of conducting dialogue. At the same time, the author himself chose a typewriter by chance. According to him, it allows you to forget about digital technologies for a while and immerse yourself in “an emotional journey with paper and ink”.
