Scaling Agentic RL: High-Throughput Agentic Training with Tunix- Google Developers Blog

Introduces Tunix, a new post-training library for scaling agentic RL training. Tunix addresses infrastructure bottlenecks by implementing asynchronous rollouts to maximize TPU utilization and eliminate execution bubbles, and a barrier-free pipelining architecture to continuously stream variable-length trajectories to the trainer. It also provides RL-specific lightweight profiling for transparency and composable agent and environment abstractions for easier integration of OSS environments.
