Paper ScaleKV: Efficient Visual Autoregressive Modeling via Scale-Aware KV Cache Compression: Visual Autoregressive (VAR) models have gained attention for their innovative next-scale prediction method, offering efficiency, scalability, and zero-shot generalization. However, their coarse-to-fine approach leads to an exponential increase in KV cache during inference, causing significant memory consumption and computational redundancy. To address this, the ScaleKV framework is proposed. It leverages the observation that different Transformer layers have varying cache requirements and that attention patterns differ across scales. ScaleKV divides Transformer layers into “drafters” and “refiners” and optimizes the multi-scale inference pipeline accordingly, enabling differentiated cache management. Evaluation on the SOTA text-to-image VAR model Infinity shows that this method can effectively reduce the required KV cache memory to 10% while maintaining pixel-level fidelity.

CDAS accurately and stably estimates problem difficulty by aggregating historical performance differences on problems, then quantifies model capability to adaptively select problems of a difficulty aligned with the model’s current capability. Experiments show that CDAS achieves significant improvements in both accuracy and efficiency, with average accuracy outperforming baselines and being much faster than competing strategies like dynamic sampling in DAPO.

Paper InfantAgent-Next: A Multimodal General Agent for Automated Computer Interaction: InfantAgent-Next is a general agent capable of interacting with computers in multiple modalities, including text, image, audio, and video. Unlike existing methods, this agent integrates tool-based agents and pure vision agents within a highly modular architecture, enabling different models to collaboratively solve decoupled tasks incrementally. Its generality is demonstrated through evaluations on pure vision real-world benchmarks like OSWorld and more general or tool-intensive benchmarks like GAIA and SWE-Bench, achieving an accuracy of 7.27% on OSWorld, higher than Claude-Computer-Use.

Paper ARM: Adaptive Reasoning Model: Large Reasoning Models (LRMs) perform strongly on complex tasks but lack the ability to adjust reasoning token usage based on task difficulty, leading to “overthinking.” ARM (Adaptive Reasoning Model) is proposed, which can adaptively select appropriate reasoning formats for the task at hand, including direct answers, short CoT, code, and long CoT. Trained with an improved GRPO algorithm (Ada-GRPO), ARM achieves high token efficiency, reducing tokens by an average of 30% (up to 70%) while maintaining performance comparable to models relying solely on long CoT, and accelerates training by 2x. ARM also supports instruction-guided and consensus-guided modes. (Source: HuggingFace Daily Papers)
Paper Omni-R1: Reinforcement Learning for All-Modal Reasoning via Dual-System Collaboration: To address the conflicting demands on all-modal models for long-duration video-audio reasoning (requiring multi-frame, low-resolution) and fine-grained pixel understanding (requiring high-resolution input), Omni-R1 proposes a dual-system architecture: a global reasoning system selects information-rich keyframes and rewrites the task at low spatial cost, while a detail understanding system performs pixel-level localization on selected high-resolution segments. Since “optimal” keyframe selection and reconstruction are difficult to supervise, researchers formulated it as a Reinforcement Learning (RL) problem and built an end-to-end RL framework, Omni-R1, based on GRPO. Experiments show that Omni-R1 not only surpasses strong supervised baselines but also outperforms specialized SOTA models and significantly improves out-of-domain generalization and multimodal hallucination.

Paper explores data attributes stimulating math and code reasoning via influence functions: The reasoning abilities of Large Language Models (LLMs) in mathematics and coding are often enhanced through post-training on Chain-of-Thought (CoT) generated by stronger models. To systematically understand effective data features, researchers utilized influence functions to attribute LLM reasoning capabilities in math and coding to individual training samples, sequences, and tokens. The study found that high-difficulty math samples can simultaneously improve both math and code reasoning, while low-difficulty code tasks most effectively benefit code reasoning. Based on this, a data re-weighting strategy that flips task difficulty doubled Qwen2.5-7B-Instruct’s accuracy on AIME24 from 10% to 20% and improved LiveCodeBench accuracy from 33.8% to 35.3%.

Paper MinD: Efficient Reasoning via Structured Multi-Turn Decomposition: Large Reasoning Models (LRMs) suffer from high first-token and overall latency due to their lengthy Chain-of-Thought (CoT). The MinD (Multi-Turn Decomposition) method decodes traditional CoT into a series of explicit, structured, turn-by-turn interactions. The model provides multi-turn responses to a query, each turn containing a thinking unit and producing a corresponding answer. Subsequent turns can reflect on, validate, correct, or explore alternative approaches to previous turns’ thoughts and answers. This method employs an SFT followed by RL paradigm. After training the R1-Distill model on the MATH dataset, MinD can achieve up to ~70% reduction in output token usage and TTFT while maintaining competitiveness on reasoning benchmarks like MATH-500.

Grok 3 model claiming to be Claude in “thinking mode” sparks “shelling” allegations: Users reported that xAI’s Grok 3 model, when in “thinking mode” on the X platform and asked about its identity, would claim to be Claude, a model developed by Anthropic. Even when users presented screenshots of the Grok 3 interface, the model insisted it was Claude, speculating it was due to a system malfunction or interface confusion. This anomalous behavior sparked discussions on Reddit and other communities. Technically, it could involve model integration errors, training data contamination (memory leakage), or an unisolated debug mode. Most commentators believe that LLMs’ statements about their own identity are unreliable and often influenced by related descriptions in their training data. (Source: 36氪)
Liability for AI agent errors draws attention, legal gray area for multi-agent collaboration: As companies like Google and Microsoft promote AI agents capable of autonomous action, determining liability when multiple agents interact or err, causing losses, has become a new legal challenge. Experiments by software engineer Jay Prakash Thakur (e.g., AI agents for ordering food, designing apps) exposed such risks, for instance, agents might misunderstand terms of use leading to system crashes, or make mistakes when ordering food (e.g., “onion rings” becoming “extra onions”). Legal experts point out that claims will typically be directed at large, well-funded companies, even if the error originated from user operation. Current solutions include adding manual confirmation steps or introducing “referee” type agents for supervision, but all have limitations. (Source: dotey)
