# DuoNeural/qwen32b-all-datasets-sft

QLoRA SFT adapter for **Qwen2.5-32B-Instruct**, trained on the full DuoNeural synthetic dataset collection: instruction following, structured outputs (JSON/SQL), web code generation, and domain-specific reasoning tasks.

Part of our ongoing effort to understand how synthetic post-training affects a large foundation model's reasoning and structured output capabilities — and whether small, targeted SFT datasets can meaningfully shift performance on standard benchmarks.

## Model Details

| Property | Value |
|---|---|
| Base Model | [Qwen/Qwen2.5-32B-Instruct](https://huggingface.co/Qwen/Qwen2.5-32B-Instruct) |
| Training Method | QLoRA (4-bit base + BF16 LoRA) |
| Hardware | NVIDIA A100 80GB |
| Training Data | DuoNeural synthetic SFT collection (5 datasets) |
| Available Checkpoints | epoch_1, epoch_2, epoch_3 (partial — see notes) |

### Training Datasets

| Dataset | Domain |
|---|---|
| DuoNeural LIMA Instruction | Instruction following (LIMA-derived) |
| DuoNeural ArchonLatentGeo | Geometric/spatial reasoning |
| DuoNeural JSON Structured | JSON schema generation and completion |
| DuoNeural SQL Expert | SQL query generation across dialects |
| DuoNeural WebCode | Frontend web code generation (HTML/CSS/JS) |

### Training Notes

- Epochs 1 and 2 completed fully
- Epoch 3 checkpoint saved at step ~803/1019 due to pod interruption — treat as a strong late-epoch checkpoint, not a completed epoch
- **Recommendation**: use `epoch_2/` for a clean fully-trained adapter, or `epoch_3/` for the best available weights

## Usage

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

base_id    = "Qwen/Qwen2.5-32B-Instruct"
adapter_id = "DuoNeural/qwen32b-all-datasets-sft"

# Load 4-bit base (matches training setup)
from transformers import BitsAndBytesConfig
bnb_cfg = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_compute_dtype=torch.bfloat16,
)

tokenizer = AutoTokenizer.from_pretrained(base_id)
base = AutoModelForCausalLM.from_pretrained(
    base_id,
    quantization_config=bnb_cfg,
    device_map="auto",
)

# Load adapter — choose epoch
model = PeftModel.from_pretrained(base, f"{adapter_id}/epoch_2", is_trainable=False)

# Inference
messages = [{"role": "user", "content": "Generate a JSON schema for a product catalog."}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
out = model.generate(**inputs, max_new_tokens=512, do_sample=False)
print(tokenizer.decode(out[0][inputs.input_ids.shape[1]:], skip_special_tokens=True))
```

**VRAM requirements:**
- 4-bit inference: ~20–22 GB (A100 40GB, RTX 3090/4090, A6000)
- BF16 inference: ~65 GB (A100 80GB, H100)

## Benchmark Status

Benchmarks (GSM8K, ARC-Challenge, HellaSwag) against the Qwen2.5-32B-Instruct base are **in progress**. Results will be added here once complete.

If SFT improves benchmark scores, we will release quantized versions (GGUF, GPTQ, AWQ, EXL2) for broader use.
