| Project status | The repository says Horovod was archived in September 2026 due to inactivity and is read-only. | The GitHub repository README states that Kubeflow Trainer is currently in alpha status and its APIs may change. |
| Purpose | Horovod is a distributed deep learning training framework for TensorFlow, Keras, PyTorch and Apache MXNet. | Kubeflow Trainer is a Kubernetes-native platform for distributed AI model training and LLM fine-tuning. |
| Scale | The project site says an existing training script can be scaled to hundreds of GPUs with a few lines of Python code. | It supports training from a single GPU to multi-node clusters, with automatic setup for DDP, FSDP, parameter servers, and gang scheduling. |
