Could you build this?
No Chunk-level key-value cache reuse for LLM inference requires low-level PyTorch/CUDA programming, deep knowledge of transformer attention mechanisms, and custom memory management.
What it would actually take: Requires deep understanding of LLM KV cache memory layouts, PagedAttention or custom CUDA/C++ kernels, and patching HuggingFace Transformers internal attention forward passes. It involves implementing radix-tree or hash-based chunk matching for prefix caching and managing GPU VRAM allocation dynamically.
Discussion
18 comments analyzed.
Competitors mentioned: vLLM, llama.cpp, LMCache, MLX
Concerns raised: Unclear what 'drop-in replacement' means exactly, No comparison against vLLM with LMCache, Website design and navigation broken, Limited clarity on implementation details (paged attention with hashing)
Feature requests: Support for llama.cpp and Vulkan, Support for ROCm
