Researchers from CMU and UIUC introduce Selection-based Structured Reasoning (SSR) to address the inefficiency of freeform reasoning in small multimodal agents. By reformulating reasoning as selecting from pre-specified natural-language candidates via likelihood scoring, SSR avoids costly generation steps. Experiments on 2B and 4B models show SSR reduces per-turn reasoning latency by over 90% and total inference latency by 28–54% while maintaining competitive success rates.

    • SSR reformulates open-ended reasoning into selection from predefined candidate sets, eliminating long-text generation overhead.
    • It leverages shared context KV Cache to parallelly compute token likelihoods for candidates, enabling fast scoring without auxiliary heads.
    • On 2B/4B small models in multimodal search benchmarks, SSR cuts reasoning latency by over 90% without sacrificing task success rates.
