Key Features

What you can do

Flexible RL Dataflows

Enables building diverse reinforcement learning algorithms by constructing dataflows in a few lines of code using a hybrid programming model.

Seamless LLM Integration

Provides modular APIs for integration with existing LLM frameworks such as PyTorch FSDP, Megatron-LM, vLLM, SGLang, and HuggingFace models.

Scalable GPU Parallelism

Supports flexible device mapping and parallelism across different GPU sets and cluster sizes to optimize resource utilization.

High Throughput Training and Inference

Leverages state-of-the-art LLM training and inference tools to achieve efficient generation and training throughput.

Memory and Communication Optimization

Uses 3D-HybridEngine for actor model resharding to reduce memory redundancy and communication overhead during training-generation transitions.
