AWS SageMaker AI enhances agent tool-calling with SFT and DPO

By PulseAugur Editorial · [2 sources] · 2026-06-03 15:56

Amazon SageMaker AI is now offering a method to enhance the tool-calling accuracy of AI agents. This is achieved by employing Supervised Fine-Tuning (SFT) and Direct Preference Optimization (DPO) techniques. The process involves training a small language model (SLM) using curated datasets and human feedback to improve its ability to select the correct tools for tasks. AI

IMPACT Enhances AI agent reliability and efficiency, potentially reducing operational costs for businesses deploying agentic applications.

RANK_REASON The article describes a new method for improving AI agent capabilities on an existing platform, rather than a novel model release.
