How Much VRAM is an open-source project aimed at helping users estimate the amount of VRAM their models will require during training or inference. This project enables users to determine the necessary hardware configuration without having to try multiple setups. It is crucial for developers and researchers engaged in deep learning model training, as it reduces the trial-and-error costs of hardware selection and improves efficiency. The project is provided under the MPL-2.0 license and is free to use.
