+# LoRA: StructEval-T (Qwen3-4B-Instruct-2507) SFT+DPO (sftdpo_v1)
+
+This repository contains a **LoRA adapter (PEFT)** for **StructEval-T style structured output tasks**.  
+It is trained as **SFT → DPO** on top of **Qwen/Qwen3-4B-Instruct-2507**.
+
+> ⚠️ This repo is **NOT** a full merged model.  
+> Load the base model first, then apply this adapter.
+
+---
+
+## Model Details
+
+- **Adapter type:** LoRA (PEFT)
+- **Base model:** Qwen/Qwen3-4B-Instruct-2507 (license: Apache-2.0)
+- **What this adapter aims to improve:**
+  - Better compliance to *structured output* constraints (JSON / schema / format-sensitive tasks)
+  - Better preference alignment via DPO on a preference dataset
+
+---
+
+## Training Data
+
+- **DPO preference dataset (main):** `u-10bei/dpo-dataset-qwen-cot`
+- **SFT starting point (adapter):** `RinnRinnmini/lora_structeval_t_qwen3_4b_sft_v1`
+  (This adapter was used as initialization before DPO.)
+
+---
+
+## Training Procedure
+
+### Stage 1) SFT (initialization)
+- Start from `Qwen/Qwen3-4B-Instruct-2507`
+- Apply SFT LoRA adapter `RinnRinnmini/lora_structeval_t_qwen3_4b_sft_v1` as the initialization point
+
+### Stage 2) DPO (this adapter)
+- **Trainer:** TRL `DPOTrainer`
+- **Framework:** Transformers + PEFT (+ Unsloth where applicable)
+- **Key hyperparameters**
+  - epochs: 1
+  - learning rate: 1e-07
+  - beta: 0.1
+  - max_length: 1024
+  - max_prompt_length: 512
+  - per_device_train_batch_size: 1
+  - gradient_accumulation_steps: 8
+  - optimizer: OptimizerNames.ADAMW_8BIT
+
+---
+
+## How to Use
+
+### Transformers + PEFT (recommended)
+
+```python
+from transformers import AutoTokenizer, AutoModelForCausalLM
+from peft import PeftModel
+import torch
+
+BASE_ID = "Qwen/Qwen3-4B-Instruct-2507"
+# BASE_ID = "unsloth/Qwen3-4B-Instruct-2507"
+
+ADAPTER_ID = "RinnRinnmini/qwen3-4b-structeval-sftdpo_v3-adapter"  # this repo (LoRA adapter)
+
+tok = AutoTokenizer.from_pretrained(BASE_ID, trust_remote_code=True, use_fast=True)
+if tok.pad_token is None:
+    tok.pad_token = tok.eos_token
+
+base = AutoModelForCausalLM.from_pretrained(
+    BASE_ID,
+    device_map="auto",
+    torch_dtype=torch.float16 if torch.cuda.is_available() else torch.float32,
+    trust_remote_code=True,
+)
+
+model = PeftModel.from_pretrained(base, ADAPTER_ID)
+model.eval()
+
+messages = [
+    {"role": "user", "content": "Return a JSON with keys a,b,c and integer values."}
+]
+prompt = tok.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+
+inputs = tok(prompt, return_tensors="pt").to(model.device)
+with torch.no_grad():
+    out = model.generate(
+        **inputs,
+        max_new_tokens=256,
+        do_sample=False,
+        pad_token_id=tok.eos_token_id,
+    )
+
+print(tok.decode(out[0], skip_special_tokens=True))
+```
+
+---
+
+## Limitations
+- This is an **adapter-only** repository. You must load the base model separately.
