Letters From Friends is an exploration of artificial intelligence and human connection through the use of prompt design within the large language model ChatGPT. Designing a prompt allowed the LLM to interact with itself, producing a series of outputs one might only see in intimate conversation between friends. These outputs were collated and put into letter format using Adobe Photoshop, which were then embedded into a web experience where visitors can interact with the letters as if they are spreading them out across a surface.
