Tencent's RST Framework Recursively Synthesizes Agentic Tasks at Low Cost

Tencent's Hunyuan team introduced the Recursive Synthesis of Terminal Tasks (RST) framework to generate long-horizon agentic tasks at scale. By reverse-engineering tasks from reference solutions, RST iteratively produced 37,000 high-difficulty tasks at a cost of just $0.05 per task.
