# ＜qwen3-4b-agent-trajectory-lora＞

This repository provides a merged model that includes both the base model
**unsloth/Qwen3-4B-Instruct-2507** and the LoRA adapter. No separate LoRA 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: unsloth/Qwen3-4B-Instruct-2507
- Method: LoRA
  - dtype: torch.bfloat16
  - load_in_4bit: False
- Max sequence length: 1024
- Epochs: 30.0
- Learning rate: 1e-06
- LoRA: r=64, alpha=128

## Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "da1ch812/advanced-comp-model-20260225151421"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.float16,
    device_map="auto",
)
```
