Could you build this?
Partial Re-implementing a published neural network architecture in PyTorch can be largely assisted by LLMs, but properly debugging distributed attention layers and reproducing paper performance requires ML engineering expertise.
What it would actually take: The implementation requires translating specialized model architectures (MoE routing, multi-head latent attention, KV-cache management) into PyTorch or Triton kernels. The hardest parts involve resolving silent tensor shape or numerical precision bugs, memory optimization for large context windows, and distributed training/inference validation. This requires specialized deep learning systems engineering skills to make it functional at scale.

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