Tencent's RST: recursive synthesis of terminal tasks at $0.05 each, boosts Qwen3.5
Tencent-Hunyuan · hf · 2026-08-07
Tencent Hunyuan presents Recursive Synthetic Terminal Tasks (RST), a recursive verified synthesis framework. Starting from seed tasks, it extends solutions, realigns verifiers, validates in sandbox, and reuses accepted tasks. After 15 rounds, it produces 37,484 tasks at $0.05 each. Difficulty rises: median solution lines 67→374, commands 40→244, DeepSeek-V4-Pro pass@4 drops 90%→2.5%. SFT improves Qwen3.5 by up to 10 points on Terminal-Bench; agentic PPO gives relative gains 20-41%. No ceiling observed.
