Could you build this?
Yes Extracting transformer attention weights and rendering them as interactive web token highlights using WebGPU/Transformers.js or a small Python backend is standard educational web development.
Discussion
20 comments analyzed.
Competitors mentioned: transformer-circuits.pub attention visualizations, Google Images transformer attention formula depictions
Concerns raised: Animation plays too fast to examine attention states step by step, Pause button resets animation instead of pausing on Chromium/Linux, Attention visualization quality not always good for explanation, Early layer attention contributions may drown out later layers in summed view, Image attention visualizations have limitations
Feature requests: Pause/resume functionality that actually pauses rather than resets, Slow playback speed option (e.g., 0.25x), Single-step buttons to advance frame-by-frame, Controls to limit which layers get summed to reveal more patterns, Per-layer attention visualization toggle

Same idea, different domain
Nobody's really built a observability & eval tool for Media & entertainment yet.
