GPT-2 inference runs in pure CMake using Q16.16 fixed-point arithmetic
A developer implemented GPT-2 model inference entirely in CMake, executing with Q16.16 integer arithmetic and supporting both a toy model and the full OpenAI GPT-2 weights.
CMake is a build configuration tool, not a runtime, so running a neural network in it is a stunt that demonstrates its Turing-completeness in practice. The choice of fixed-point arithmetic reveals what you sacrifice when the host language lacks native floating-point support.

GPT-2 inference is implemented entirely in CMake script with no other runtime dependency.
Arithmetic uses Q16.16 fixed-point integer representation rather than floating point.
The full model loads weights from HuggingFace's openai-community/gpt2 safetensors checkpoint.
