ByteAsk
Ships C/C++/CUDA pull requests already compiled, sanitized and tested, not just generated.
ByteAsk is a coding agent specialized in C, C++ and CUDA: it finds the few functions a bug touches (not the whole repo), fixes the issue, then builds and runs your test suite with sanitizers (ASan/UBSan/TSan) and static analysis before handing you a pull request. It cites language and industry standards relevant to the code (MISRA for automotive, FIX for trading, etc.), and can run on-prem, air-gapped, or with your own model key, with zero data retention. The landing page cites a real fix in nlohmann/json and a 68% lower cost than alternatives, backed by Y Combinator.
What holds up
- +Every PR arrives already built, sanitized (ASan/UBSan/TSan) and tested, not just generated.
- +Runs on-prem or air-gapped, or with your own model key — code stays inside your network.
- +Cites real contributions to projects like llama.cpp, LLVM and nlohmann/json, not just a demo.
Mind the limits
- −Scoped to C/C++/CUDA — not useful if your codebase is in another language.
- −Choosing a hosted model (rather than on-prem/your own GPUs) sends code outside your network.
