These characters are often based on fictional media, celebrities, or are original creations designed for purposes like creative writing assistance or text-based adventure games. The service transitioned from a public beta to its current website in September 2024. The company has also developed infrastructure for machine learning research, such as a Slurm on Kubernetes solution, and has been involved in news events related to AI performance and legal matters.
