microGPT in C explores low-level optimizations
Published on May 3, 2026, the repository presents a dependency-free implementation of microGPT in plain C, using AVX2 intrinsics, fixed-width dot-product kernels, and a fast approximation of the exponential function.

What happened and what to do
On May 3, 2026, the repository presented a plain C implementation of Karpathy’s microGPT with no dependencies. The post says the code uses AVX2 intrinsics, fixed-width dot-product kernels, and a fast approximation of the exponential function; its aim is to make training and inference inspectable and enable exploration of low-level optimizations.
A company could use this approach to evaluate inference or training workloads on its own infrastructure, comparing implementations and monitoring resource use and latency. The work could include a C proof of concept, reproducible tests, and dashboards for tracking results, without assuming the implementation fits every model or environment.
How the consultancy can help
Wendelmaques can diagnose the opportunity and environment constraints, define an evaluation scope, and implement and operate a proof of concept with tests and monitoring suited to the client’s infrastructure.
