Qwen has released QwenGyre, an RL framework designed for training AI agents on extremely long, complex tasks. Its Elastic Scheduler dynamically reallocates GPUs between rollout and training without interrupting live executions, delivering up to 1.85× speedup over Colocate and 1.78× over Async. The Trajectory Processor converts branching executions into prefix‑shared trajectory trees, providing bounded, deduplicated training samples.
