original project established engineer Arvind Sanjeev: created an unusual typewriter called the 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 Chat GPT. If you don’t know the details, you may decide that a ghost has moved into the car.

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 the 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 GPT-3 OpenAI API. To enter correspondence with the artificial intelligence, all that remains is to insert the card.
The great GPT-3 language model has been trained on millions of books and websites; its job is to statistically predict which word is most likely to appear after the suggested phrase, i.e. 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 adjust the “temperature” of the neural network’s creativity and the length of its responses, so two additional handles and an OLED display appeared on the case .
According to Sanjeev, his project is a kind of statement about the relationship between man and artificial intelligence, as well as man and typewriter, which form a creative symbiosis. The typewriter format helps a person to forget the omnipresent digital presence for a while and immerse himself in it “an emotional journey through paper and ink”.
