Learn from Your Mistakes: Self-Correcting Masked Diffusion Models

⋅

Masked diffusion models (MDMs) have emerged as a promising alternative to autoregressive models, enabling parallel token generation while achieving competitive performance. Despite these advantages, MDMs face a fundamental limitation: once tokens are unmasked, they remain fixed, leading to error accumulation and ultimately degrading sample quality. We address this by proposing a framework that trains a model to perform both unmasking and correction. By reusing outputs from the MDM denoising network as inputs for corrector training, we train a […]

GPU Compass – open-source, real-time GPU pricing across 20+ clouds [P]

⋅

We maintain an open-source catalog of cloud GPU offerings (skypilot-catalog, Apache 2.0). It auto-fetches pricing from 20+ cloud APIs every 7 hours. We made it browsable – 50 GPU models, 2K+ offerings, on-demand and spot pricing, historical trends. A few other GPU comparison tools already use our catalog as their data source. Figured we’d make the raw data visible to everyone. submitted by /u/Shot-Patience-9874 [link] [comments]

Trump FCC threatens to enforce equal-time rule on late-night talk shows

Trump FCC threatens to enforce equal-time rule on late-night talk shows

⋅

The Federal Communications Commission today issued a warning to late-night and daytime talk shows, saying these shows may no longer qualify for an exemption to the FCC’s equal-time rule. Because the FCC is chaired by vocal Trump supporter Brendan Carr, changing how the rule is enforced could pressure shows into seeking out more interviews with Republican candidates. The public notice providing what the FCC calls “guidance on political equal opportunities requirement for broadcast television stations” appears to be […]

Report: China approves import of high-end Nvidia AI chips after weeks of uncertainty

Report: China approves import of high-end Nvidia AI chips after weeks of uncertainty

⋅

On Wednesday, China approved imports of Nvidia’s H200 artificial intelligence chips for three of its largest technology companies, Reuters reported. ByteDance, Alibaba, and Tencent received approval to purchase more than 400,000 H200 chips in total, marking a shift in Beijing’s stance after weeks of holding up shipments despite US export clearance. The move follows Beijing’s temporary halt to H200 shipments earlier this month after Washington cleared exports on January 13. Chinese customs authorities had told agents that the […]

Author(s): Dr. Leon Eversberg Originally published on Towards AI. The next generation of RAG: How PageIndex improves retrieval accuracy without semantic search Retrieval-augmented generation (RAG) adds the external knowledge contained in a large collection of documents to an LLM. RAG uses optimized vector databases to efficiently store embedding vectors and find relevant matches to a given query. Reasoning-based RAG versus vector-based RAG.

Method teaches generative AI models to locate personalized objects

Method teaches generative AI models to locate personalized objects

⋅

Say a person takes their French Bulldog, Bowser, to the dog park. Identifying Bowser as he plays among the other canines is easy for the dog-owner to do while onsite. But if someone wants to use a generative AI model like GPT-5 to monitor their pet while they are at work, the model could fail at this basic task. Vision-language models like GPT-5 often excel at recognizing general objects, like a dog, but they perform poorly at locating […]

De-ICE Disco at the Googleplex

⋅

When Renee Good and Alex Pretti were murdered, and I saw the incredible courage of people in Minneapolis in the face of state brutality, I had to find some way to show that tech workers stand with Minnesota, even if our leaders don’t. I signed the ICEout petition, and I’d encourage you to do the same. I’ve also been talking to the press about why I signed it, and on the Wired Uncanny Valley podcast Kate Drummond asked […]

Multi-Agent Memory from a Computer Architecture Perspective: Visions and Challenges Ahead

⋅

arXiv:2603.10062v1 Announce Type: new Abstract: As LLM agents evolve into collaborative multi-agent systems, their memory requirements grow rapidly in complexity. This position paper frames multi-agent memory as a computer architecture problem. We distinguish shared and distributed memory paradigms, propose a three-layer memory hierarchy (I/O, cache, and memory), and identify two critical protocol gaps: cache sharing across agents and structured memory access control. We argue that the most pressing open challenge is multi-agent memory consistency. Our architectural framing provides […]

Lap2: Revisiting Laplace DP-SGD for High Dimensions via Majorization Theory

⋅

arXiv:2602.23516v1 Announce Type: new Abstract: Differentially Private Stochastic Gradient Descent (DP-SGD) is a cornerstone technique for ensuring privacy in deep learning, widely used in both training from scratch and fine-tuning large-scale language models. While DP-SGD predominantly relies on the Gaussian mechanism, the Laplace mechanism remains underutilized due to its reliance on L1 norm clipping. This constraint severely limits its practicality in high-dimensional models because the L1 norm of an n-dimensional gradient can be up to sqrt(n) times larger […]
