List me the 20 top C++ contributors of trending repository in AI

First, I need to find trending GitHub repositories related to AI that are primarily written in C++. I'll search for 10 such repositories, sorted by stars to ensure they are trending.
Once I have a list of trending C++ AI repositories, I will retrieve the top 5 contributors for each of these repositories. This will provide a pool of contributors from which the top 20 overall can be identified.

Notes:

  • This ranking is based on contributor counts reported within each trending C++ AI repository.
  • If you meant “top 20 contributors to a single trending repository,” tell me which repo (e.g., jd-opensource/xllm, OriginHubAI/MyScaleDB, openai/openai-reflect), and I’ll list that repo’s top 20 specifically.
