Today's research features potentially transformative efficiency advances and critical safety findings. A symmetry-aware Taylor approximation claims to achieve constant-cost self-attention per token—if validated, a fundamental breakthrough. Meta introduces Fault Tolerant HSDP enabling training on 100K+ GPUs with graceful failure recovery.

Theoretical advances include polylog(1/δ) sampling complexity for diffusion models (exponential improvement), formal proofs that transformers learn factored representations in orthogonal subspaces, and a relative-budget theory explaining when RLVR succeeds. Grad2Reward extracts dense process rewards directly from LLM judge gradients, addressing reward sparsity in long-form reasoning.

Self-Attention at Constant Cost per Token via Symmetry-Aware Taylor Approximation

Shows self-attention is efficiently computable to arbitrary precision with constant cost per token by decomposing Taylor expansion into symmetric chains of tensor products, achieving orders-of-magnitude efficiency gains.

arXiv:2602.00294v1 Announce Type: cross Abstract: The most widely used artificial intelligence (AI) models today are Transformers employing self-attention. In its standard form, self-attention incurs costs that increase with context length, driving demand for storage, compute, and energy that is now outstripping society's ability to provide them.

arXiv:2602.00277v1 Announce Type: cross Abstract: Large-scale training systems typically use synchronous training, requiring all GPUs to be healthy simultaneously. In our experience training on O(100K) GPUs, synchronous training results in a low efficiency due to frequent failures and long recovery time. To address this problem, we propose a novel training paradigm, Fault Tolerant Hybrid-Shared Data Parallelism (FT-HSDP). FT-HSDP uses data parallel replicas as units of fault tolerance. When f
