Could you build this?
No Building a record-breaking LLM inference engine optimized for specific hardware like the RTX 5090 requires specialized CUDA kernel programming and low-level GPU architectural knowledge.
What it would actually take: The core engine requires C++, CUDA, and custom CUTLASS or Triton kernels tailored to NVIDIA Blackwell tensor cores supporting micro-scaling formats (MXFP4/MXFP6). Critical engineering challenges include implementing custom speculative decoding algorithms, paged KV-cache memory management for 1M context windows, and low-overhead continuous batching schedulers.
