Attention is a lookup. Each token builds a query, compares it against every key in the sequence, and pulls value vectors weighted by the match. Stack that 96 layers deep and you get a frontier model.
Video covers the full pipeline: Q/K/V, attention scores, encoder blocks. https://t.co/xMoP46WxCm

@Phoenixyin13: I think this is a top-notch work in ICML 2026. The attention mechanism of traditional Transformers is essentially point-to-point matching: it cuts input into a bunch of tokens (discrete points), computes similarity between Query and Key, and then weights the Value. In NLP...
Introduces the ICML 2026 paper Functional Attention, which treats functions as first-class citizens and replaces softmax point-to-point similarity with structured linear operators. It addresses issues of discretization, resolution sensitivity, and high computational complexity in traditional Transformers when handling continuous functions. Achieves or surpasses SOTA in tasks like PDE solving and 3D segmentation, and exhibits strong OOD generalization.

Adaptive Computation Depth via Learned Token Routing in Transformers
This paper presents Token-Selective Attention (TSA), a differentiable token routing mechanism that learns to skip unnecessary computations per token in transformer layers, reducing token-layer operations by 14–23% with minimal quality loss on language modeling tasks.
