Could you build this?
No This requires deep systems programming, GPU kernel engineering (CUDA/Triton), distributed cluster orchestration across diverse cloud providers, and custom compiler design.
What it would actually take: Needs engineers with deep expertise in writing optimized CUDA/Triton kernels, building hardware-abstracted domain-specific languages (like their proprietary Emma language), and formally verifying GPU memory topologies. The infrastructure requires a resilient multi-cloud distributed orchestrator that handles fault-tolerant distributed checkpointing, InfiniBand/RoCE network topologies, and dynamic GPU provisioning across heterogeneous providers.

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