Reasoning-Aware Cross-Modal Association Unlearning in Multimodal Large Reasoning Models

This paper introduces cross-modal association unlearning for multimodal large reasoning models (MLRMs), targeting the removal of specific visual-to-knowledge associations rather than whole samples or concepts. The proposed VKCR method localizes edits to a compact parameter subspace and counterfactually rebinds reasoning behavior to suppress target leakage while preserving non-sensitive knowledge. New benchmarks CLEAR-R and MLLMU-R evaluate leakage, hallucination, and utility, showing VKCR reduces image-conditioned target leakage across tasks.

Why it matters: Addresses a novel privacy problem in multimodal reasoning models with a parameter-efficient method and benchmarks, offering practical value for AI safety and unlearning research.

Rubric Curriculum RL Improves RLVR in Non-Verifiable Domains

The paper introduces Rubric Curriculum RL (RcRL), a method that exploits the generation-verification gap in domains without ground-truth rewards by combining pairwise preferences over rollouts with a curriculum over rubric criteria. This creates a more discriminative and non-stationary training signal, avoiding the plateau seen in baselines. RcRL achieves a 70.5% human win rate on creative writing and improves HealthBench performance by 14.6% (full set) and 25.4% (consensus subset), outperforming all training baselines.

Why it matters: This presents a concrete, novel training method with measurable gains in open-ended domains, addressing a key limitation of RLVR.

NextGAN: Towards Simple and Scalable GAN Training for Image and Video Generation

NEXTGAN trains a scalar critic by regressing its input gradient onto displacements between independently paired reference and generated features at interpolated locations in frozen representation spaces. The authors state that, for a fixed generator, this regression is equivalent to an adversarial objective with a gradient-energy penalty, while the generator keeps the standard potential-based GAN update. The method adapts pre-trained image and video generators with up to 14B parameters without auxiliary losses, online teacher scores, or trajectories. On ImageNet 256x256 it reports one-step FIDs of 2.87 with pixel-space JiT-B and 1.54 with latent-space DiT-XL/1 (1.36 for its adversarial form), and a single Wan2.1-1.3B model supports one-, two- and four-step text-to-video sampling, scoring 83.13 VBench total at two steps.

Why it matters: It offers a simpler adversarial training recipe for few-step image and video generation, backed by one-step FID and VBench comparisons, which is useful for researchers and practitioners building fast generative models.

A.S.E 2.0: How Repository Context Impacts the Security of LLM-Generated Code

This paper introduces CASE-Bench, a benchmark of 145 repository-level tasks derived from real CVEs across 51 projects, to study how repository context affects the security of LLM-generated code. Experiments with 13 context construction methodshol and six LLMs show that functionality-oriented context improves functional pass rates more than secure pass rates, and that withholding safeguards or inserting insecure examples significantly increases exploitable code. Coding agents observe relevant safeguards in only 27-36% of trajectories, highlighting the need for security-aware context construction.

Why it matters: Provides concrete, recent evidence and a new benchmark on a critical but understudied aspect of LLM code security, offering actionable insights for developers and researchers.

Process-based catchment model matches deep-learning accuracy across three continents

A new process-based hydrological model, CaRT+, built on physical laws and refined with AI assistance, achieves accuracy comparable to LSTM neural networks on catchments in Britain, the US, and Australia. With 35 parameters per catchment and no daily neural network, it reaches median Nash-Sutcliffe efficiencies of 0.863 and 0.765 in held-out years on British and US data, and outperforms LSTMs on Australian catchments. The results suggest that catchment-scale laws exist as laws of form, with shared constitutive families and only parameters learned.
