# qwen25-7b-sft-merged-v5v6-a50
This repository provides a **fully merged model** fine-tuned from
**Qwen2.5-7B-Instruct** using **QLoRA + Unsloth**.
Two SFT models (v5 and v6) were trained independently, then combined via
weight interpolation (alpha=0.5). This is a **complete model** — no adapters
or additional weights are needed.
## Training Objective
This model 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/Qwen2.5-7B-Instruct
- Method: QLoRA (4-bit) + Unsloth, merged into base model
- Max sequence length: 2048
- Epochs: 2
- Learning rate: 5e-5
- LoRA: r=32, alpha=64
- Post-training: weight interpolation of v5 and v6 (alpha=0.5)
## Usage
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
model_id = "plotMaker/qwen25-7b-sft-merged-v5v6-a50"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
model_id,
torch_dtype=torch.bfloat16,
device_map="auto",
)
```
