Why we included this project

TNN comes from Tencent's Youtu and Guangying labs, and it's built to run neural networks on devices where compute is tight. The framework builds on ncnn and Rapidnet, two earlier inference engines, and adds optimizations that make it a good fit for phones: the same runtime can also target x86 and NVIDIA GPUs for desktop and server work. It's been shipped inside Mobile QQ, Weishi, and Pitu, so the design has been shaped by real production use rather than just benchmarks. If your team needs to embed a model in a mobile app and also serve it elsewhere, TNN is worth a closer look.
