Could you build this?
Partial Writing a basic forward pass for GPT-2 in C++ can be guided by AI, but writing high-performance, multithreaded CPU SIMD kernels from scratch in modern C++20 requires solid low-level systems programming.
What it would actually take: The architecture involves raw C++20 parsing Hugging Face/OpenAI weights and tokenizers, implementing matrix multiplication via BLAS or custom AVX2/AVX-512 vector intrinsics, and handling streaming KV-cache management. Developers need deep expertise in memory layouts, cache locality, and SIMD parallelization to achieve practical real-time CPU token generation.
