QFoldAgent: An Autonomous Quantum Optimization Multi-Agent System for Protein Structure Prediction

QFoldAgent is a closed-loop multi-agent framework for 5-residue tetrahedral-lattice folding that uses a design agent, a VQE-based quantum-classical pipeline, and a feedback agent to iteratively refine Hamiltonian penalties. It reduces median RMSD from 3.64 Å to 3.20 Å on QDockBank fragments and raises structural validity from 87.5% to 98.7% on unseen sequences.

SeT-Diff: Towards Semantic Foundation Models for HPC Telemetry and Time-Series

SeT-Diff is the first foundational model for compute node telemetry and time-series. Using a diffusion-based approach conditioned on semantic descriptions of sensors, it decouples system dynamics from dataset structure. Experiments on a real supercomputer show a reconstruction MAE of 0.047 and thermal inference MAE of 0.033, with zero-shot permutation stability.

Concept-based Visual Counterfactual Explanations with Diffusion Models

This paper introduces C-VCE, a diffusion framework that integrates the classifier into the generative model via a concept bottleneck layer, eliminating the need for external noise-robust classifiers. C-VCE allows users to toggle semantic concepts during sampling, generating minimal edits while preserving the rest of the image. It includes a probabilistic regularizer to balance prediction change and similarity to the original, plus a gradient-based mask to confine modifications. On CelebA, C-VCE achieves comparable or better flip rates with visually closer and less distorted counterfactuals.

Can AMD Break the CUDA Moat? AMD Advancing AI 2026

This article analyzes AMD's progress in AI accelerator software, moving from a zero-percent chance of success to a meaningful possibility, thanks to leadership changes, open-source strategies, and key customers like Anthropic and Microsoft. However, AMD faces two major risks: slow production ramp of the Helios rack due to design issues, and insufficient internal GPU clusters for development and testing. The article provides specific recommendations to AMD's management and details the MI455X silicon and Helios rack architecture.

Memory Efficient Audio Synthesis with Decoupled Temporal Depth Diffusion Transformers

Apple has released Siri Expressive Voices, powered by a memory-efficient audio synthesis architecture called a detokenizer. This architecture converts semantic audio tokens from the foundation model into high-fidelity audio within the tight compute and memory budget of the Apple Matrix Coprocessor (AMX). It features a three-component design—a streaming encoder, a temporal decoder, and a depth decoder—that systematically decouples temporal and depth processing. A single reusable depth decoder with Diffusion Transformer (DiT)-style stage conditioning generates all RVQ levels autoregressively, replacing dedicated per-level decoders. Causal sliding window attention with fixed-window key-value caching yields constant memory complexity independent of sequence length. Deployed on the AMX, the de…

"Google and Reddit do not own the Internet," web scraper says after court win

AI labs don't know how to make you trust them

A semiotic analysis of 27 brands reveals that AI labs like Anthropic and OpenAI occupy the 'Sovereign Doctrine' quadrant, the weakest trust position. The study identifies two dimensions: Authority vs. Evidence and Human vs. System, dividing trust into four territories. AI labs lack heritage or trackable numbers, making their trust strategy thin. The gap lies in warm and verifiable territories like Crowd Wisdom and the warm edge of Hard Proof.

Leading AI models (even Grok) are all a bunch of leftist punks

An opinionated guide to which AI to use to do stuff

Ethan Mollick's AI guide has evolved from focusing on chat models a year ago to now emphasizing agentic systems that can do hours of work in one go. Gemini is dropped due to lack of a mature product in the Codex/ChatGPT Work/Cowork category. The guide explains the confusing naming of ChatGPT and Claude's multiple agent modes, notably that switching to Work mode on ChatGPT mobile gives the code interpreter internet access.

AMD Advancing AI 2026: Talking CDNA5 with AMD's Alan Smith

At AMD's Advancing AI 2026 event, Alan Smith, AMD Corporate Fellow and Chief Architect for Datacenter GPUs, detailed the new CDNA5 architecture. The architecture moves from the legacy GCN foundation to RDNA, adopts a split compute chiplet design for HPC (double precision) and AI (tensor) workloads, deprecates Wave64 in favor of Wave32 on four SIMD32 units, expands VGPR per wave from 256 to 1024, and revamps the cache hierarchy with per-base-die client-side L2 caches replacing the Infinity Cache, improving global atomics bandwidth and efficiency.
