Cpp-Code-LargeCpp-Code-Large
Cpp-Code-Large is a large-scale corpus of C++ source code comprising more than 5 million lines of C++ code. The dataset is designed to support research in large language model (LLM) pretraining, code intelligence, software engineering automation, and static program analysis for the C++ ecosystem.
By providing a high-volume, language-specific corpus, Cpp-Code-Large enables systematic experimentation in C++-focused model training, domain adaptation, and downstream code… See the full description on the dataset page: https://huggingface.co/datasets/ajibawa-2023/Cpp-Code-Large.LiveCodeBench-CPP
LiveCodeBench-CPP: An Extension of LiveCodeBench for Contamination Free Evaluation in C++
Overview
LiveCodeBench-CPP includes 454 problems from the release_v6 of LiveCodeBench, covering the period from October 2024 to May 2025. These problems are sourced from AtCoder (287 problems) and LeetCode (167 problems).
AtCoder Problems: These require generated solutions to read inputs from standard input (stdin) and write outputs to standard output (stdout). For unit testing, the… See the full description on the dataset page: https://huggingface.co/datasets/nvidia/LiveCodeBench-CPP.magenta-realtime-mlx-cpp
Magenta RealTime — C++ MLX runtime bundle
This dataset is a re-packaging of
Google's Magenta RealTime weights
for the C++ MLX runtime in
rhymeswithlion/magenta-realtime-mlx-cpp.
It contains exactly what mlx-stream needs at startup; nothing more, nothing
less. The upstream .pt / .npy checkpoints are intentionally not
mirrored here — they're only useful for the (Python) re-export tooling on the
project's main distribution.

Dataset Card for Opencores
In the process of continual pre-training, we utilized the publicly available VGen dataset.
VGen aggregates Verilog repositories from GitHub, systematically filters out duplicates and excessively large files, and retains only those files containing \texttt{module} and \texttt{endmodule} statements.
We also incorporated the CodeSearchNet dataset \cite{codesearchnet}, which contains approximately 40MB function codes and their documentation.… See the full description on the dataset page: https://huggingface.co/datasets/LLM-EDA/vgen_cpp.qwen3-8-27B-llama-cpp-Q8Candidates_unmatched_cppLongBench-v2-for-llama.cppLongBench v2 converted for the llama.cpp perplexity multiple choice tool.
