Could you build this?
No Implementing a custom high-performance LLM inference engine with custom NVFP4 GPU kernels, speculative decoding algorithms, and custom recurrent-state caching requires specialized GPU systems programming and ML systems research.
What it would actually take: Requires low-level CUDA, CUTLASS, or Triton programming specifically targeting NVIDIA Blackwell/Hopper microarchitectures for NVFP4 precision execution. Developers need deep expertise in parallel computing, GPU memory hierarchies, KV-cache/Mamba-style recurrent state optimization, and speculative tree decoding algorithms like StairCut.
