Amazon SageMaker AI has launched a Multi-Step Reinforcement Learning (MTRL) framework, supporting end-to-end training of agents to accomplish multi-step tasks.
AWS has launched the Multi-Turn Reinforcement Learning (MTRL) feature, enabling users to train large‑model agents on SageMaker AI using full task trajectories and final outcome feedback, without requiring step‑level annotations. A end-to-end demonstration is provided using Wordle as an example, covering AgentCore deployment, data preparation, GRPO training, reward design, and cost analysis.
