ALFWorld samples: 8 (doubled from 2c7's 4)
DBBench samples: 4 (reduced from 2c7's 9)
Focus on: take/put/move command understanding, two-object tasks, invalid action recovery

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: 2048
Epochs: 2
Learning rate: 6e-06
LoRA: r=128, alpha=128
Custom samples: 12 (ALF:8 + DB:4) × 70 = 840 (~25%)

Usage

python

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

base = "Qwen/Qwen3-4B-Instruct-2507"
adapter = "TToyo2511/ttoyo_advance_2c12" #★TTT20260226 2c12版

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