RAEv2 advances representation-first tokenization with >10x faster convergence and improved generation, tested on text-to-image and world models. NVIDIA's Gated DeltaNet-2 innovates linear attention with channel-wise gates, outperforming KDA and Mamba-3 at 1.3B parameters on language modeling and reasoning tasks. Studies on subword tokenization reveal only some benefits at scale, while data filtering research suggests that with enough compute, no filtering may be optimal at around 1e30 FLOPs. Mechanistic interpretability updates propose clustering features by joint firing patterns for better geometry understanding. OpenAI's AI-assisted breakthrough on an ErdΕs unit-distance math problem sparks debate on AI's role in mathematical research. Harnesses remain key for capability improvements in agent infrastructure.
