It supports multi-turn training by adapting traditional RL methods with token-level masking. It features a decorator-based interface for defining tools and reward functions, enabling seamless extension and ease of use. To support high-throughput training, it implemented asynchronous execution of tool calls and reward computations, and design a centralized resource management system for scalable environment coordination. A suite of prebuilt tools and environments are provided. News 4/2026 SWE and SimuScene : Added SWE-Bench style (R2E-Gym) tasks and SimuScene training. 3/2026 Resource System : Added a resource system for better environment and container management, and integrated SWE like tasks training. 12/2025 Method-Based Tool : Support using @tool for a class method 12/2025 Verl Update : Updated verl to 0.6.x version. 08/2025 Multi-Modal (Vision) Agent Training Support : Thanks to the powerful template system, AgentFly now supports training vision-language agents! 🎉 Train agents that can see and understand visual content, including GUI automation and image-based QA. See our predefined training examples for ready-to-use scripts. --- 08/2025 Chat Template System : A flexible framework for creating conversation templates with multi-model support, vision capabilities, and tool integration.
