Best for
AI engineers, researchers, and developers building or deploying distributed AI models who need to mitigate memory and hardware cost limitations.
Key capabilities
Increases large AI model inference speed, achieving up to double the speed compared to vLLM in some reported cases.
Supplies a domain-specific LLM solution that can be trained with a few hundred dollars in approximately half a day.
Delivers an open-source solution for cloning ChatGPT functionality, featuring a complete RLHF pipeline.
Decreases memory consumption and lowers hardware requirements for training and fine-tuning Stable Diffusion models.
Limitations and risks
Currently supports only Linux operating systems and requires specific NVIDIA GPU hardware (compute capability >= 7.0).
Getting started
Install the framework via pip and import it directly into an existing PyTorch model definition to begin.
