Name: advanced-comp-model-20260225191215
Availability: InStock

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-20260225191215"

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