+# Qwen3-4B Agent Trajectory (v17)
+
+This repository provides a **fully merged model** fine-tuned from **Qwen/Qwen3-4B-Instruct-2507** using Unsloth.
+
+Unlike standard adapter repositories, this repository contains the **merged weights**, meaning you do not need to load the base model separately.
+
+## Training Objective
+
+This model is trained to improve **multi-turn agent task performance**
+on ALFWorld (household tasks).
+
+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.
+
+## Data Processing
+
+- Train/Validation Split: 95% / 5%
+- Random Seed: 3407 (used for shuffling and initialization)
+- Loss Masking: Loss was computed only on the assistant's responses. User prompts and observations were masked during training (`train_on_responses_only` was applied to `<|im_start|>assistant\n`).
+
+## Training Configuration
+- **Base model**: Qwen/Qwen3-4B-Instruct-2507
+- **Method**: LoRA + Unsloth (Merged in 16-bit)
+- **Max sequence length**: 8192
+- **Epochs**: 1
+- **Learning rate**: 3e-06
+- **LoRA**: r=16, alpha=32
+- **PER_DEVICE_TRAIN_BATCH_SIZE** = 4
+- **GRAD_ACCUM** = 4
+- **WARMUP_RATIO** = 0.15
+- **WEIGHT_DECAY** = 0.05
+- **NEFTUNE_NOISE_ALPHA** = 5.0
+- **VAL_RATIO** = 0.05

+## Usage
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+import torch
+
+model_id = "choco800/qwen3-4b-agent-v17"
+
+tokenizer = AutoTokenizer.from_pretrained(model_id)
+model = AutoModelForCausalLM.from_pretrained(
+    model_id,
+    torch_dtype=torch.bfloat16,
