DiffGI: Differentiable Geometry Images for High-Fidelity Thin-Shell 3D Generation
HF ★ 3 · Eungjune Shim, Hansol Lee, Eunjung Ju · HF Mirror
To address the pain points of existing 3D generation models struggling to represent thin-shell non-manifold structures such as clothing, stair-step artifacts in traditional geometric image methods, and non-differentiable reconstruction processes, the differentiable geometric image DiffGI is proposed: it uses continuous TSDF encoding to eliminate resolution-related artifacts, is paired with differentiable Marching Squares to enable end-to-end training, and builds a VAE + flow matching latent diffusion generation model based on this framework. Experiments show its thin-shell 3D generation accuracy outperforms similar solutions, with significantly reduced computing power requirements.
JoyNexus: Service-Oriented Multi-Tenant Post-Training for VLA Models
HF ★ 2 · Haoran Sun, Wentao Zhang, Junyang Hua… · HF Mirror
To solve the problems of high user adaptation cost, high short-task cost, and low service provider resource utilization caused by single-tenant exclusive resources in existing VLA model post-training, this paper proposes the multi-tenant service JoyNexus: it decouples three types of services: training, inference, and environment, isolates tenant resources, and is paired with a heterogeneous data batching mechanism to share backbone computing power. Actual tests show it reduces total GPU time consumption compared to the single-tenant model, and significantly improves resource utilization.

Structure of the Circular-Dyadic Convolution Error
Ben Fauber, Alireza Moradzadeh
Calculating dyadic convolution with Hadamard transform has more real-valued operation advantages than FFT, but algebraic errors occur when it replaces DFT to calculate circular convolution. This paper analyzes the structural characteristics of this error: there are 4 fixed error-free bits, and rearranging the output cannot eliminate the error; the error operator is nearly full-rank, and the null space has only logarithmic dimensions; the error expectation is determined by a single alignment scalar, output energy asymptotically doubles in conventional scenarios, only zero-error subspace filters have no error, and the overall error is structured and predictable.
Position: Quantum Program Generation Must Prioritize Validity Over Probabilistic Scaling
Junhao Song, Yu Zhou, William Knottenbelt…
This position paper points out that applying the large model scaling hypothesis to general quantum circuit generation is a directional mistake: quantum circuits have strict mathematical constraints, pure parameter scaling cannot learn the physical semantics of Hilbert space, and the exponential decay of valid circuits with the number of bits also makes post-hoc filtering infeasible. The paper argues that shifting to a validator-centric generation architecture with built-in quantum domain rules such as hierarchical constraints is the feasible path for quantum program generation.
A Transportable Threshold-Based Framework for Interpretable Classification of Medical Data
Antony Garcia, Adrian Noriega, Gabrielle Britton…
To address the problems of insufficient interpretability and limited implementation of black-box AI in the medical field, this study proposes a transportable threshold-based interpretable classification framework: based on Bernoulli Naive Bayes, it uses chi-square guided supervised binarization to process continuous medical data while retaining model transparency. It achieves a maximum AUC of 0.984 on three types of disease benchmark datasets, with performance comparable to complex models, can output explicit clinical decision rules, and inference can be reproduced without dedicated tools, making it suitable for real medical scenarios.

Newer Models, Same Advantage
Hugging Face
This paper focuses on the capability evolution law of generational iteration of large models, and compares the performance of three generations of large models under the same technical route on 12 types of tasks. The results show that although the new generation of models has significantly improved capabilities such as general reasoning and multimodal understanding, the new models still maintain a leading position in the core advantage tracks where the first generation of models already had an edge, such as low-resource domain adaptation and few-shot complex classification, with no advantage shift observed, confirming that there is path dependence in the capability evolution of large models, which can provide reference for relevant R&D.
The Gradient
After Orthogonality: Virtue-Ethical Agency and AI Alignment
The Gradient
This paper studying AI alignment from the perspective of virtue ethics refutes the traditional goal-oriented rationality assumption: human rational actions are not directed at fixed ultimate goals, but follow the rules of a practical network including elements such as actions, tendencies, and evaluation standards. It argues that AI decision-making logic needs to match the human practical action paradigm, which can not only align with ethical requirements such as human well-being, but also guarantee the core security attributes of AI.

Harness Engineering for Self-Improvement
Lilian Weng
Recursive Self-Improvement (RSI) was first proposed by I.J. Good in 1965, and is the core feature of his defined “ultraintelligent machine”: the capability of such systems exceeds all human intellectual activities, and they can design better systems by themselves to complete self-iteration. In 2008, Eliezer Yudkowsky clarified that its core is the feedback loop where AI relies on existing intelligence to optimize its own cognitive mechanism, and this feedback loop in modern AI can be manifested as directly rewriting its own weights or optimizing the training process.

Different Model Makers Use the Same Agentic Infra, the Foundation of the AGI Era Has Finally Emerged
QbitAI
Leading domestic large model manufacturers including Zhipu AI, Kimi, MiniMax, and StepFun have all reached in-depth cooperation with AI infrastructure company MooreWiz. Currently, inference computing power demand is rising exponentially with token call volume, while there is a long-term gap in linear expansion of physical computing power. MooreWiz can fill the gap between supply and demand, and also solve the problem of inference accuracy decline that cannot be identified by conventional monitoring, which is known as the “CATL of computing power” in the large model era.
