Loss is applied to all assistant turns in the multi-turn trajectory, enabling the model to learn environment observation, action selection, tool use, and recovery from errors.

Training Configuration

Base model: unsloth/Qwen3-4B-Instruct-2507
Method: LoRA (full precision base)
Max sequence length: 2048
