🔴 Omni-WorldBench: Towards a Comprehensive Interaction-Centric Evaluation for World Models — score 95
Sources: huggingface
Video--based world models have emerged along two dominant paradigms: video generation and 3D reconstruction. However, existing evaluation benchmarks either focus narrowly on visual fidelity and text--video alignment for generative models, or rely on static 3D reconstruction metrics that fundamentall
🔴 OpenResearcher: A Fully Open Pipeline for Long-Horizon Deep Research Trajectory Synthesis — score 75
Sources: huggingface
Training deep research agents requires long-horizon trajectories that interleave search, evidence aggregation, and multi-step reasoning. However, existing data collection pipelines typically rely on proprietary web APIs, making large-scale trajectory synthesis costly, unstable, and difficult to repr

🟡 Look Where It Matters: High-Resolution Crops Retrieval for Efficient VLMs — score 65
Sources: huggingface
Vision-language models (VLMs) typically process images at a native high-resolution, forcing a trade-off between accuracy and computational efficiency: high-resolution inputs capture fine details but incur significant computational costs, while low-resolution inputs advocate for efficiency, they pote
🟡 LongCat-Flash-Prover: Advancing Native Formal Reasoning via Agentic Tool-Integrated Reinforcement Learning — score 55
Sources: huggingface
We introduce LongCat-Flash-Prover, a flagship 560-billion-parameter open-source Mixture-of- Experts (MoE) model that advances Native Formal Reasoning in Lean4 through agentic tool-integrated reasoning (TIR). We decompose the native formal reasoning task into three independent formal capabilities, i.
🟡 VideoDetective: Clue Hunting via both Extrinsic Query and Intrinsic Relevance for Long Video Understanding — score 45
Sources: huggingface
Long video understanding remains challenging for multimodal large language models (MLLMs) due to limited context windows, which necessitate identifying sparse query-relevant video segments. However, existing methods predominantly localize clues based solely on the query, overlooking the video's intr

🟢 SpatialBoost: Enhancing Visual Representation through Language-Guided Reasoning — score 35
Sources: huggingface
Despite the remarkable success of large-scale pre-trained image representation models (i.e., vision encoders) across various vision tasks, they are predominantly trained on 2D image data and therefore often fail to capture 3D spatial relationships between objects and backgrounds in the real world, c
🟢 Repurposing Geometric Foundation Models for Multi-view Diffusion — score 25
Sources: huggingface
While recent advances in generative latent spaces have driven substantial progress in single-image generation, the optimal latent space for novel view synthesis (NVS) remains largely unexplored. In particular, NVS requires geometrically consistent generation across viewpoints, but existing approache
🟢 mSFT: Addressing Dataset Mixtures Overfiting Heterogeneously in Multi-task SFT — score 15
Sources: huggingface
Current language model training commonly applies multi-task Supervised Fine-Tuning (SFT) using a homogeneous compute budget across all sub-datasets. This approach is fundamentally sub-optimal: heterogeneous learning dynamics cause faster-learning tasks to overfit early while slower ones remain under
🟢 Manifold-Aware Exploration for Reinforcement Learning in Video Generation — score 5
Sources: huggingface
Group Relative Policy Optimization (GRPO) methods for video generation like FlowGRPO remain far less reliable than their counterparts for language models and images. This gap arises because video generation has a complex solution space, and the ODE-to-SDE conversion used for exploration can inject e
