Best practices for multi-turn reinforcement learning in Amazon SageMaker AI

TutoSartup excerpt from this article:
More ways to act mean more ways to satisfy the reward without doing the task, and the environment the agent trains against can quietly corrupt the training signal... We cover how to build a training environment you can trust, set up an external evaluation, design a reward aligned with the end task, manage what changes once the agent runs for multiple turns, and monitor the metrics that tell you w...
