original project demonstrated engineer Arvind Sanjeev: he created an unusual typewriter called Ghostwriter, which is able to communicate with a person. All thanks to artificial intelligence – the GPT-3 language model “lives” inside the system, on which the chat bot is built ChatGPT. If you do not know the details, you can decide that a ghost has moved into the machine.

Sanjiv took the Brother AX-325 electric typewriter, released in the nineties of the last century, as the basis for the Ghostwriter project. Using reverse engineering, he collected signals from the keyboard, to which he connected the popular Arduino controller. The latter sends signals to the Raspberry Pi single board computer, which acts as a network interface to connect to the OpenAI GPT-3 API. To enter into correspondence with artificial intelligence, all that remains is to insert paper.
The large GPT-3 language model has been trained on millions of books and websites; its task is to statistically predict which word is most likely to appear following the suggested phrase, that is, the text that is typed on the Ghostwriter keyboard. GPT-3 can work as a chatbot or generate text, including writing poetry. Having started experimenting with his invention, the author realized that he also needed to regulate the “temperature” of the creative of the neural network and the length of its responses – this is how two additional handles and an OLED display appeared on the case.
According to Sanjeev, his project is a kind of statement regarding the relationship between man and artificial intelligence, as well as man and typewriter, which form a creative symbiosis. The typewriter format helps a person forget regarding the ubiquitous digital presence for a while and immerse himself in “an emotional journey through paper and ink”.
