qwen3-4b-agent-trajectory-lora
This repository provides a LoRA adapter fine-tuned from
Qwen/Qwen3-4B-Instruct-2507 using LoRA + Unsloth.
This repository contains the full-merged 16-bit weights. No adapter loading is required.
Training Objective
This adapter is trained to improve multi-turn agent task performance
on ALFWorld (household tasks) and DBBench (database operations).
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: Qwen/Qwen3-4B-Instruct-2507
- Method: LoRA (full precision base)
- Max sequence length: 4096
- Epochs: 2
- Learning rate: 4e-05
- LoRA: r=64, alpha=128
Usage
Since this is a merged model, you can use it directly with transformers.
