NexForge: Requirement-Driven Task Synthesis Scales LLM Agent Capabilities
NexForge is a framework that automatically synthesizes diverse, executable agent tasks and expert trajectories from high-level capability requirements, removing the need for domain-specific infrastructure. The system generated thousands of terminal and office tasks, significantly improving the performance of Qwen3.5-35B-A3B on benchmarks such as Terminal-Bench 2.0 and GDPval. Scaling up to 43,200 tasks enabled the training of Nex-N2 models, which achieve state-of-the-art open-source results and surpass several proprietary systems.
Why it matters: NexForge demonstrates a scalable approach to expanding LLM agent capabilities by automating task synthesis from requirements, reducing manual engineering and enabling broader domain coverage.
