Could you build this?
No Developing EXL3 low-bit quantizations and DFlash speculative decoding kernels for ExLlamaV3 at 262k context requires deep CUDA/C++ kernel engineering and low-level LLM quantization math.
What it would actually take: This requires C++/CUDA expertise modifying ExLlamaV3 kernels to implement custom 4.00 bpw dequantization routines, draft-target speculative decoding synchronization (DFlash2), and paged attention memory management for extreme 262k context windows on consumer 24GB GPUs. Deep understanding of GPU memory hierarchies, tensor core assembly, and LLM inference engine architectures is required.
