EP240: Small AI agents beat giants with Orchard

Title: Orchard: An Open-Source Agentic Modeling FrameworkSource: http://arxiv.org/abs/2605.15040v1Summary:Orchard provides a scalable open-source framework for agentic modeling, introducing reusable environment primitives and training recipes that enable LLMs to achieve state-of-the-art performance on complex tasks. It addresses critical gaps in agent infrastructure by standardizing sandbox management and introducing credit-assignment SFT for learning from unresolved trajectories.
