What is Step-Audio-R1.1
Step-Audio-R1.1 is the world's first open-source native speech reasoning model launched by StepFun. The model tops the globally authoritative speech reasoning benchmark with 96.4% accuracy, surpassing many leading models. The model features deep speech reasoning, real-time response, and scalable chain-of-thought capabilities, and can think in real time like a human when processing speech end-to-end. Step-Audio-R1.1 can be used to analyze complex audio scenarios, such as cats arguing or language learning audio. The weights of Step-Audio-R1.1 have been uploaded to HuggingFace, and the complete real-time speech API will be launched in February, providing developers and users with a powerful speech processing tool.
