これは何か
Step is the general model series StepFun has released since April 2023. StepFun was founded in Shanghai in 2023 by Jiang Daxin and others, with multimodality and on-device efficiency as main directions. Step-1 is a model in the hundred-billion-parameter range, and versions such as Step-1V accept image input; later releases add lightweight variants for phones and other devices. The series is offered through cloud interfaces and partly in open form, covering dialogue, image understanding and content generation.
なぜ覚えておく価値があるか
It placed a hundred-billion-parameter general model and a lightweight version fit for phones on the same product line, betting on multimodality and on-device at once — an early, explicit version of that combination among start-up labs.
