TL;DR
Pure-text reasoning struggles with global geometric and spatial constraints in complex problems. FigR addresses this by embedding active visual thinking into multi-turn reasoning through end-to-end reinforcement learning, externalizing intermediate visual hypotheses as executable figures, and adaptively regulating when visual reasoning is invoked. The approach yields substantial gains on challenging math benchmarks (e.g., +13.12% on AIME 2025 and +11.00% on BeyondAIME over a strong base), demonstrating improved stability and reliability of multimodal reasoning. These results highlight the practical value of figure-guided reasoning for hard analytical tasks and point to a generalizable direction for interpretable multimodal reasoning systems.
Abstract
Complex reasoning problems often involve implicit spatial, geometric, and structural relationships that are not explicitly encoded in text. While recent reasoning models have achieved strong performance across many domains, purely text-based reasoning struggles to represent global structural constraints in complex settings. In this paper, we introduce FIGR, which integrates active visual thinking into multi-turn reasoning via end-to-end reinforcement learning. FIGR externalizes intermediate structural hypotheses by constructing visual representations during problem solving. By adaptively regulating when and how visual reasoning should be invoked, FIGR enables more stable and coherent reasoning over global structural properties that are difficult to capture from text alone. Experiments on challenging mathematical reasoning benchmarks demonstrate that FIGR outperforms strong text-only chain-of-thought baselines. In particular, FIGR improves the base model by 13.12% on AIME 2025 and 11.00% on BeyondAIME, highlighting the effectiveness of figure-guided multimodal reasoning in enhancing the stability and reliability of complex reasoning.
