Flower AI is an open-source federated learning framework for building distributed ML systems that enables multiple clients to collaboratively train models while protecting raw data privacy.
Its main purpose is to simplify the development of federated learning systems, enabling developers, researchers, and enterprises to jointly train AI models without sharing raw data.
Users typically need basic Python programming and machine learning knowledge. The framework provides detailed tutorials and templates to help migrate from existing projects or start from scratch.
It integrates with PyTorch, TensorFlow, JAX (with Flax), Hugging Face Transformers, fastai, and Pandas, among other mainstream tools and frameworks.
The framework follows federated learning's core principle: training data stays on local devices or servers, and only model parameters or updates are uploaded to a central server for aggregation, avoiding direct transfer of raw data.
Flower AI is an open-source framework and is available for free.
Ideal for sectors with stringent data privacy requirements, such as healthcare, financial services, autonomous driving, and any scenario needing cross-organization AI training.
Install the Flower library, use its CLI tool 'flwr new' to generate a project template, or clone the official example repository to get started quickly.
They are integrated, with Flower AI focusing on research flexibility and algorithm development, while NVIDIA FLARE emphasizes production readiness; after integration, Flower-developed code can run within the FLARE environment.
