Youtu-Agent: Scaling Agent Productivity with Automated Generation and Hybrid Policy Optimization
Youtu-Agent is a flexible, high-performance framework for building, running, and evaluating autonomous agents. Beyond topping the benchmarks, this framework delivers powerful agent capabilities, e.g. data analysis, file processing, and deep research, all with open-source models. Additionally, the framework supports experience-based learning and end-to-end RL training to enhance agent capabilities.
Key highlights:
- Verified performance: Achieves state-of-the-art performance on WebWalkerQA (71.47%) and GAIA (72.8%) using purely open-weight models (e.g.,
DeepSeek-V3), establishing a strong open-source baseline.
- Automated Agent Generation: Introduces two paradigms: a Workflow mode for standard tasks and a Meta-Agent mode for complex requirements. The framework supports automated generation of tool code, prompts, and configurations, achieving over 81% tool synthesis success rate.
- Continuous Experience Learning: The Agent Practice module enables low-cost continuous evolution via Training-Free GRPO. Agents accumulate experience and improve performance (e.g., +5.4% on AIME 2025) through in-context optimization without parameter updates.
- Scalable and Stable Agent RL: The Agent RL module provides a complete pipeline for end-to-end reinforcement learning. By integrating with distributed frameworks, it addresses stability and scalability challenges, achieving 40% training speedup and scaling to 128 GPUs.
- Open-source friendly & cost-aware: Optimized for accessible, low-cost deployment without reliance on closed models.
- Practical use cases: Out-of-the-box support for tasks like data analysis, literature review, personal file organization, retrieval-augmented generation, and PPT generation.
- Flexible architecture: Built on openai-agents, with extensible support for diverse model APIs (from
DeepSeek to gpt-oss), tool integrations, and framework implementations.

🌟 Benchmark Performance
Youtu-Agent is built on open-source models and lightweight tools, demonstrating strong results on challenging deep search and tool use benchmarks.
- WebWalkerQA: Achieved 60.71% accuracy with
DeepSeek-V3-0324， using new released DeepSeek-V3.1 can further improve to 71.47%, setting a new SOTA performance.
- GAIA: Achieved 72.8% pass@1 on the text-only validation subset using
DeepSeek-V3-0324 (including models used within tools). We are actively extending evaluation to the full GAIA benchmark with multimodal tools, and will release the trajectories in the near future. Stay tuned! ✨
