Accelerate multimodal RL training with SkyRL on Amazon SageMaker HyperPod

Guide for GRPO post-training on SageMaker HyperPod

Amazon published a guide showing how to use SageMaker HyperPod with the open-source SkyRL framework to run GRPO post-training on a Qwen3-VL-8B vision-language model for visual maze navigation.

The training improved the maze solve rate from 43.75% to over 95% on a fixed 64-maze evaluation set.

The guide covers cluster setup, Ray integration, and monitoring via Amazon Managed Grafana.
