AI-powered foundation model
StepFun is a foundation model AI agent offering a Chinese AI company building the Step series of multimodal foundation models and consumer AI assistants. Founded in 2023 and based in Shanghai, China, StepFun helps developers and consumers in China automate foundation model work and get results faster.
StepFun takes text, images and voice as input and produces text, images and voice. It is powered by StepFun models, with the vendor managing prompts, models and updates. It connects to tools such as WeChat, Feishu, DingTalk and REST APIs, so the agent works inside existing workflows.
