This paper presents an architectural study of OpenClaw, an open-source personal AI assistant platform that orchestrates large language model agents across 77+ messaging channels. We analyze its gateway-centric control plane, plugin-based extensibility model, streaming context engine, and layered security architecture.
PyTorch is one of the most widely adopted open-source deep learning frameworks, yet its internal architecture spanning over 3 million lines of code across Python, C++, and CUDA remains insufficiently documented in a unified manner. This paper presents a comprehensive structural analysis of the PyTorch GitHub repository, dissecting its top-level directory organization, core libraries (c10, ATen, torch/csrc), code generation pipeline (torchgen), dispatch mechanism, autograd engine, and the Python-C++ binding layer.
