Could you build this?
No Writing a custom GGUF-native inference engine in Rust and CUDA optimized for low cold-start latency requires deep systems programming, GPU memory management, and CUDA kernel optimization expertise. Vibe coding cannot generate reliable, performant GPU runtime code or low-level tensor operations.
What it would actually take: Building this requires a Rust runtime interfacing with raw CUDA/C++ kernels via FFI or cuBLAS/CUTLASS, implementing custom GGUF parsing, memory-mapped tensor loading, and activation caching. The hard parts are writing highly tuned fused GPU kernels and managing hardware-level memory bandwidth to minimize cold-start latency. It requires senior systems and HPC/ML-infra engineers experienced in CUDA architecture and tensor compilers.
