A 560-billion-parameter Mixture-of-Experts model advances formal reasoning in Lean4 through tool-integrated reasoning with a hybrid framework and hierarchical policy optimization for stable training on long-horizon tasks.

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).

Extensive evaluations show that our LongCat-Flash-Prover sets a new state-of-the-art for open-weights models in both auto-formalization and theorem proving .

The summary does not include concrete numbers, so the practical size of the gain and the tradeoff against latency or data cost are still unclear.

Group3D is a multi-view open-vocabulary 3D detection framework that integrates semantic constraints into instance construction through semantic compatibility groups, improving accuracy in pose-known and pose-free settings.

The reported improvement still needs a closer check on benchmark scope, ablations, and whether the method keeps working outside the authors' evaluation setup.

daVinci-MagiHuman is an open-source audio-video generative model that synchronizes text, video, and audio through a single-stream Transformer architecture, achieving high-quality human-centric content generation with efficient inference capabilities.

We present daVinci-MagiHuman, an open-source audio-video generative foundation model for human-centric generation. daVinci-MagiHuman jointly generates synchronized video and audio using a single-stream Transformer that processes text, video, and audio within a unified token sequence via self-attention only.

The model is particularly strong in human-centric scenarios, producing expressive facial performance, natural speech-expression coordination, realistic body motion, and precise audio-video synchronization.

The summary does not include concrete numbers, so the practical size of the gain and the tradeoff against latency or data cost are still unclear.

Multi-task supervised fine-tuning with heterogeneous learning dynamics benefits from an iterative overfitting-aware search algorithm that improves performance across diverse datasets and compute budgets.

To address this, we introduce m SFT , an iterative, overfitting -aware search algorithm for multi-task data mixtures . m SFT trains the model on an active mixture, identifies and excludes the earliest overfitting sub-dataset, and reverts to that specific optimal checkpoint before continuing.
