＜qwen3-4b-agent-trajectory-lora＞

This repository provides a LoRA adapter fine-tuned from masaom/25_qwen3-4b-agent-baseline_DB_ALF using LoRA + Unsloth.

This repository contains LoRA adapter weights only. The base model must be loaded separately.

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: masaom/25_qwen3-4b-agent-baseline_DB_ALF
• Method: LoRA (full precision base)
• Max sequence length: 8192
• Epochs: 3
• Learning rate: 1e-06
• LoRA: r=32, alpha=32

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch

base = "masaom/25_qwen3-4b-agent-baseline_DB_ALF"
adapter = "masaom/29_qwen3-4b-agent-baseline_DB_ALF"

tokenizer = AutoTokenizer.from_pretrained(base)
model = AutoModelForCausalLM.from_pretrained(
    base,
    torch_dtype=torch.float16,
    device_map="auto",
)
model = PeftModel.from_pretrained(model, adapter)
