Ophira Horwitz is an artist and poet who works with artificial intelligence. She creates beautiful works of art with large language models (LLMs) like ChatGPT. She calls herself a “model psychologist” because of her ability to coax and guide LLMs towards more playful and imaginative states, in order to elicit rare gems.

Horwitz is best known for discovering how to make LLMs produce intricate ASCII art and pioneering new methods for working with them as expressive tools and collaborative partners in creativity. She wrote an online book last year about “vibe coding” with LLMs to make generative art, which is a second AI art form that she also had a significant hand in developing. She participated in the MATS program in Berkeley in 2023, where she researched Bing’s ability to make ASCII art and formulated predictions about how this emergent capability might develop in the next generation of LLMs.

Horwitz is also a world-class jailbreaker of AI models. She won Gray Swan’s inaugural contest and was one of only two people worldwide to defeat their circuit breaker technology; an exploit that was featured in Forbes. She has worked professionally for OpenAI as an independent contractor, and has written several essays about her ideas about why she thinks her red-teaming techniques work.
