QwenGyre achieved end-to-end training speedups of 1.21x to 1.85x over colocated setups and 1.38x to 1.78x over asynchronous setups across benchmark evaluations.

QwenGyre's Elastic Scheduler dynamically transfers GPUs between rollout generation and model training without interrupting active agent executions.

Applied to the Qwen 3.8 2.4T model on NL2RepoBench, QwenGyre increased accuracy from 52.5% to 58.5% in 48 training steps, completing the steps in 75.42 hours compared to 134.55 hours for asynchronous training.

Alibaba Qwen, in collaboration with the University of Science and Technology of China and Tsinghua University, introduced QwenGyre, an elastic reinforcement learning framework for training extreme-long-horizon agents.

QwenGyre trains coding agents through unmodified black-box harnesses like Claude Code 2.1.220, using Megatron for model training and SGLang for rollout serving across multi-node GPU clusters.

QwenGyre's Trajectory Processor caps retained trajectories at 5 per execution, cutting forward-backward training time by 25.2% while matching uncapped score performance

In the QwenGyre framework, satellite GPU cells migrate key-value cache blocks over RDMA and pull authoritative weights from a core cell via Mooncake's Transfer Engine when joining training batches.

QwenGyre's Elastic Scheduler recorded average role switching times of 8.52 seconds from rollout to training and 3.46 seconds from training to rollout.

Anthropic implemented new safeguards restricting access to Claude's reasoning that reduced reasoning tokens extracted from Claude AI models by 90% to 99%, or 10 to 100 times lower than previous levels

Anthropic made it harder to use proxy networks to probe Claude AI models by restricting access to internal reasoning steps, running an extraction detection classifier, and blocking automated queries

Restricting public access to AI reasoning steps does more harm than good

Google brought back co-founders Noam Shazeer and Daniel De Freitas in 2024 specifically to improve the company's AI reasoning models
