As the title and description of the GitHub repo suggest, I’m working on a small project for purely educational purposes, with the goal of implementing generative model inference (small models capable of modeling 2D distributions) based on the Flow Matching paradigm in C. I’ve worked on generative AI models based on Flow Matching from a more “abstract” perspective, using frameworks like PyTorch, and I wanted to understand what goes on behind the scenes. The repository is still a work in progress and is also one of my first "serious" projects in C.

Could you build this?
Partial Writing a basic C program is vibe-codeable, but implementing mathematical differential equation solvers and tensor inference for Continuous Normalizing Flows/Flow Matching from scratch without high-level ML frameworks requires strong numerical computing and mathematical skills.
What it would actually take: The implementation requires raw C99/C11 with custom linear algebra operations (BLAS or manual matrix math), numerical ODE solvers (such as Euler or Runge-Kutta integration), and weights parsing from PyTorch checkpoints. The hard part is implementing numerical integration stably in C without external ML runtime dependencies, ensuring correct numerical gradients and tensor dimensions. It requires expertise in numerical analysis, generative diffusion/flow matching mathematics, and low-level C programming.
