inclusionAI / AReaL
Summary
AReaL is an open-source, fully asynchronous reinforcement learning (RL) training system designed for large reasoning and agentic models. Developed by Tsinghua IIIS and Ant Group, it builds upon ReaLHF and emphasizes open-source principles by providing training details, data, infrastructure, and models for reproducibility. AReaL offers flexibility for agentic and online RL training, boasts stable and industry-leading speed, and delivers cutting-edge performance across math, coding, search, and customer service agents. Recent developments include AReaL-SEA, a self-evolving data synthesis engine that, when combined with AReaL, enabled a 235B MoE model to surpass GPT 5 and match Gemini 3.0 Pro on Math-bench. The system also supports Ascend NPU devices and offers a lightweight version, AReaL-lite, for rapid prototyping.
Key takeaway
For AI Architects and MLOps Engineers seeking to develop or deploy large reasoning and agentic models, AReaL offers a robust, open-source asynchronous RL training platform. Its demonstrated scalability and performance, including surpassing GPT 5 with AReaL-SEA, suggest it can significantly accelerate model development and deployment. You should explore its integration capabilities with existing agentic runtimes and consider its support for various hardware, including Ascend NPUs, to optimize your training infrastructure.
