Could you build this?
No Implementing ~300x KV-cache compression with linear complexity requires novel deep learning research, custom CUDA/Triton kernels, and mathematical expertise in matrix factorization and attention mechanisms.
What it would actually take: Requires writing custom GPU kernels (CUDA/C++ or Triton) integrated into an inference engine like vLLM or Hugging Face Transformers. The engineering demands deep theoretical knowledge of attention KV-caches, structured matrix factorization (SMF), and low-level GPU memory bandwidth optimization to achieve compression without unacceptable perplexity degradation.

Concerns raised: Cosine similarity not suitable for attention compression, Lack of clear demonstration that it works
