Qwen3.5 9B

POST-TRAINING / SOURCE DISCLOSURE

What the Qwen3.5 post-trained family report says

The reviewed card describes progressively harder agent environments and asynchronous reinforcement-learning infrastructure. Its architecture and multimodal training are documented separately from its post-training objective.

• Agent environments with increasing task complexity
• Large-scale asynchronous reinforcement learning

The card reviewed is for 397B-A17B. It does not name a complete policy objective; the background links do not establish that every Qwen3.5 checkpoint used the same optimizer.
