In keeping with an announcement from StepFun on January 15, its open-source mannequin Step-Audio-R1.1 has ranked No.1 worldwide on a significant worldwide analysis leaderboard.
StepFun mentioned that the Synthetic Evaluation Speech Reasoning benchmark—one of the vital authoritative third-party evaluations for native audio fashions—has been up to date, with Step-Audio-R1.1 taking the highest place. The benchmark is extensively thought to be a key trade commonplace for assessing fashions that course of uncooked audio immediately and carry out advanced logical reasoning, with core analysis metrics together with accuracy and first-token latency.
In keeping with StepFun, similar to giant language fashions, speech fashions should possess robust reasoning capabilities to allow higher-level intelligence and extra pure human–machine interplay. With an accuracy rating of 96.4%, Step-Audio-R1.1 outperformed main fashions akin to Grok, Gemini, and GPT-Realtime, setting a brand new all-time document on the benchmark. By way of the general steadiness between efficiency and velocity, Step-Audio-R1.1 considerably outperforms comparable speech fashions.
Step-Audio-R1, initially launched by StepFun, is acknowledged because the world’s first open-source native speech reasoning mannequin. It’s able to end-to-end speech understanding and reasoning with out introducing further latency, enabling the system to “assume as quickly because it hears,” very like a human listener.
Its core capabilities embrace:
- Superior speech reasoning
- Actual-time response efficiency
- Scalable chain-of-thought (CoT) reasoning within the audio area
Step-Audio-R1.1, the most recent upgraded model, additional enhances real-time conversational efficiency and complicated speech reasoning capabilities. A full real-time speech API is scheduled for launch in February. The presently accessible chat mode already integrates the R1.1 core, supporting streaming inference that permits the mannequin to assume and communicate concurrently.
