NEW paper from Alibaba. A 30B MoE with only 3B active params matches Qwen3-235B on real tool-use workloads. AgenticQwen-30B-A3B: 50.2 average on TAU-2 + BFCL-V4 Multi-Turn. AgenticQwen-8B: 47.4. Both more than double their vanilla Qwen baselines and close most of the gap to a 235B model. How: two RL flywheels run in parallel. - The reasoning loop mines the model's own errors into harder problems each round. - The agentic loop grows simple linear tool-use trajectories into multi-branch behavior trees. - Simulated users actively try to mislead the agent. The training distribution gets harder on its own. Why it matters for agent devs: you can stop paying frontier prices for routine tool-use workloads. And the flywheel recipe is reusable. Generate your hard examples from your own agent's failures, not from static synthetic data.
