CaLR: Causal Latent Revision for Robust Diffusion Reasoning

Read the original on arXiv AI →

CaLR: Causal Latent Revision for Robust Diffusion Reasoning proposes a framework that combines autoregressive and diffusion language models by reformulating reasoning as constrained latent optimization. The method uses a causal topology matrix from an expert model and implicit differentiation to perform gradient-guided thought revision, enforcing logical consistency and allowing dynamic self-correction of intermediate steps during parallel generation. Empirical results show CaLR achieves state‑of‑the‑art performance on complex benchmarks, surpassing strong autoregressive baselines and demonstrating superior robustness in constrained tasks such as Sudoku.

DCGC: Draft-Conditioned Global Correction for Complex Reasoning with Masked Diffusion Models

DCGC is a Masked Diffusion Model framework that performs global correction of flawed reasoning traces in Large Language Models. It uses an imperfect solution draft from an upstream solver as auxiliary context and combines task‑specific supervised fine‑tuning with a Dynamic Dual‑CFG inference mechanism that separates problem‑only and joint problem‑draft branches. Experiments on math, code, and knowledge reasoning benchmarks show that DCGC outperforms standard sampling and simpler CFG variants, and it can improve full test‑set accuracy even when ground‑truth failure labels are unavailable.

Test-Time Scaling with Diffusion Language Models via Reward-Guided Stitching

The paper introduces Stitching Noisy Diffusion Thoughts, a self‑consistency framework that transforms low‑cost diffusion‑sampled reasoning into a reusable pool of step‑level candidates. By sampling many diverse trajectories with a masked diffusion language model, scoring each intermediate step with a process reward model, and stitching the highest‑quality steps across trajectories, the method recomputes only the final answer, separating exploration from evaluation. Experiments on math reasoning benchmarks show that step‑level recombination improves accuracy by up to 23.8% on six tasks while reducing latency by up to 1.8× compared to traditional diffusion models and unified architectures.

Flow Reasoning Models: Turning Flows Into Efficient Recurrent Reasoners

Flow Reasoning Models (FRMs) are a new framework that turns continuous flow models into efficient recurrent reasoners for structured tasks. By self‑conditioning a flow model on its own past outputs, FRMs iteratively refine solutions, allowing parallel decision making and revision. The authors introduce Fixed‑Point Forcing (FPF) to mitigate exposure bias at deeper recursion, and report near‑perfect solve rates on Sudoku‑Extreme, Zebra, and Maze‑Unique, outperforming existing masked‑diffusion and specialized baselines while using far fewer inference FLOPs.
