Could you build this?
No Writing deep learning training routines, backpropagation, and transformer attention kernels directly in WebGPU / WGSL from scratch requires deep expertise in GPU compute shaders and machine learning systems.
What it would actually take: A production version requires custom WebGPU/WGSL compute shader kernels implementing forward and backward passes for matrix multiplication, softmax, RMSNorm, layer-scaled projections, and AdamW optimization in the browser. It involves high-performance low-level graphics and compute programming, memory buffer management, and numerical stability tuning. This requires specialized expertise in systems ML engineering and GPU compute shaders.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
