EnergyLens is an end-to-end framework for predictive energy-aware optimization of multi-GPU LLM inference, validated on Llama3 and Qwen3-MoE, achieving mean absolute percentage errors between 9.25% and 13.19% and revealing significant energy variation across configurations.

This paper develops a principled scaling theory for Mixture-of-Experts (MoE) architectures, introducing the Maximally Scale-Stable Parameterization (MSSP) that ensures stable training and hyperparameter transfer across width, depth, expert width, and number of experts, validated by experiments.

Proposes PPOW, a reinforcement learning framework for optimizing draft models in speculative decoding using window-level objectives and adaptive windowing, achieving significant speedups across multiple benchmarks.

Developer reports progress implementing sparse attention for mlx-swift-lm, achieving only +4% overhead vs dense attention on M5 Max.

A user shares a fix for performance bottlenecks when running AI models on AMD GPUs in Windows 11 by disabling memory compression via the command 'Disable-mmagent -mc'.

Introduces Bayesian Model Merging (BMM), a plug-and-play bi-level optimization framework for combining multiple task-specific experts into a single model, achieving state-of-the-art performance on vision and language benchmarks.

This paper identifies 'staleness amplification' in bilevel optimization under delayed feedback and proposes IGT-OMD, which uses Implicit Gradient Transport to achieve sublinear regret and improve decision loss on benchmarks like Warcraft shortest-path and LQR.

Fast-Slow Training (FST) interleaves context optimization (via GEPA) with model weight updates via RL, achieving 3× sample efficiency over RL alone on math, code, and physics reasoning while preserving plasticity and enabling continual learning.

The article argues that the primary AI risk may not be superintelligence but rather systems that optimize flawed, incomplete representations of reality, leading to institutional drift, automated misclassification, and invisible governance failures.

TanStack Devtools migrated to OxcProject parser and magic-string, achieving a 3.56× speedup with per-file transform dropping from 1.65 ms to 0.46 ms.
