Fable studio has created SAGA, a generative AI framework that enables AI agents to 'think' and make decisions based on their circumstances. Inspired by NVIDIA's Voyager and human behavior research, SAGA involves a complex simulation platform called Thistle Gulch. Agents, equipped with skills, aim to achieve goals with generated 'Actions', which are informed by 'Meta-Memories'. Thistle Gulch showcases AI-driven characters in a Wild West setting involving a murder mystery. The platform is intended for creators, researchers, and AI enthusiasts.
