Could you build this?
No This is deep systems/ML systems research involving low-level GPU memory management, custom CUDA/C++ kernels, and novel exact-addressing memory architectures to bypass KV cache limits.
What it would actually take: Requires developing custom low-level GPU kernels and custom memory-paging mechanisms (bypassing conventional attention KV caches like vLLM/SGLang). The architecture relies on an exact-addressing persistent memory store with microsecond lookup, custom execution engines, and formal proof verification systems. Building this demands deep expertise in GPU systems programming (CUDA/C++), hardware memory hierarchies, and compiler/runtime internals.
Discussion
16 comments analyzed.
Competitors mentioned: Long-term degrading cache for FFN augmentation, Beam search in key space systems
Concerns raised: Paper lacks clarity on inputs/outputs and algorithm steps with type information, GitHub repository does not exist, Unclear how it differs from standard caching, Requires 46GB GPU hardware, No implementation details or algorithm provided by design
Feature requests: Step-by-step algorithm documentation with type information, Define query input format and output specifications, Public GitHub implementation

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