The end really helped me with understanding their motivations: > Flashlight’s modular internals make it a powerful research framework for research frameworks. > We’re already using Flashlight at Facebook in our research focused on developing a fast speech recognition pipeline, a threaded and customizable train-time relabeling pipeline for iterative pseudo-labeling, and a differentiable beam search decoder. > Our ongoing research is further accelerated by the ability to integrate external platform APIs for new hardware or compiler toolchains and achieve instant interoperability with the rest of Flashlight. They found it easier and faster to make a framework optimized for their research than to try to iterate on a larger and more complex codebase. I think there is less cognitive overhead and less things to change when experimenting with a new idea, and since they've optimized for fast rebuild times, it is much faster to try out new things. They get native integration with the C++ ecosystem for free and since their team all know C++ well, it makes sense to just do it in plain C++.
