# State-of-the-art Large Reasoning Model Built Using Only Synthetic Data on AMD GPUs

## Model Summary
We introduce **SAND-Math-Qwen2.5-32B** and **SAND-MathScience-DeepSeek-Qwen32B**, state-of-the-art reasoning models in the 32B parameter range, built entirely using a synthetic data pipeline running on the **AMD ROCm™ stack** and **AMD Instinct™ MI325 GPUs**.
By prioritizing data difficulty along with quantity, we demonstrate that high-difficulty synthetic data can elevate prior-generation models to match or exceed modern proprietary models. `SAND-Math-Qwen2.5-32B` is fine-tuned from **Qwen2.5-32B-Instruct** on just **14k synthetic math samples**, achieving strong reasoning capabilities with minimal data outperforming other data distillation and post training approaches. `SAND-MathScience-DeepSeek-Qwen32B` is fine-tuned from **DeepSeek-R1-Distill-Qwen-32B** on a compact dataset of **27k samples** (15k Math + 12k Science), achieving a generational leap in performance that rivals **Qwen3-32B**.
We are releasing the models, datasets, and code to empower the community to build their own state-of-the-art reasoning models using AMD hardware.
## 📊 Benchmark Results
We conducted extensive experiments to validate that our pipeline yields superior results compared to models trained on significantly larger datasets.
### 1. Bridging the Generational Gap
Fine-tuning the Qwen2.5-based **DeepSeek-R1-Distill-Qwen-32B** on our mixed Math/Science dataset allows it to rival and even surpass the next-generation **Qwen3-32B** on key benchmarks.
| Model | AIME24 | AIME25 | MATH500 | GPQA |
| :--- | :---: | :---: | :---: | :---: |
| DeepSeek-Distilled-Qwen32B (Base) | 72.6 | 54.9 | 94.3 | 62.1 |
| EXAONE Deep 32B | 72.1 | 65.8 | 95.8 | 66.1 |
| Qwen3-32B (Thinking mode) | 81.4 | 72.9 | **97.0** | 68.4 |
| **SAND-MathScience-DeepSeek-Qwen32B (Ours)** | **83.85** | **78.33** | 93.85 | **68.72** |
### 2. Efficiency: Unlocking Reasoning with Less Data
Using only **14k synthetic math samples** and standard SFT (no RL), our approach outperforms models trained on datasets 5x to 50x larger.
| Model | Data Size | AIME24 | AIME25 | MATH500 | GPQA |

| Qwen2.5-32B-Instruct (Base) | - | 16.7 | 13.3 | 83.4 | 53.5 |
| DeepSeek-R1-Distill-Qwen-32B | 800k | 72.6 | 54.9 | **94.3** | **62.1** |
| Light-R1-32B | 79k | 73.0 | 64.3 | 93.3 | 60.6 |
| OpenThinker-32B | 114k | 66.0 | 53.3 | 89.4 | 57.6 |

## ⚙️ The Synthetic Data Pipeline
Our results are powered by a 4-stage automated pipeline running on AMD hardware that prioritizes **difficulty and novelty** over volume. Unlike datasets that recycle easy problems, our pipeline leverages a Teacher Model (`GPT-OSS120b`) to generate, validate, and systematically "hike" the difficulty of reasoning problems.
### Pipeline Stages
1. **Stage 1: QA Generation & Consistency** 🛠️
- Generates novel problems from scratch
- Enforces correctness by requiring the teacher to generate multiple independent solution paths
- Only questions where all answers align are kept
2. **Stage 2: De-duplication & Decontamination** 🧹
- Removes internal duplicates via embedding similarity
- **Crucial Step:** Scans against known test sets (AIME, MATH, GPQA) to ensure zero contamination
3. **Stage 3: Difficulty Hiking** 🏔️
- Moderately challenging questions are rewritten by the teacher model
- Introduces deeper reasoning chains, added constraints, or cross-domain logic
- Systematically elevates complexity
- Configurable step primarily used when initial generation yields insufficient volume of high-difficulty samples

## 🚀 Quick Start
### Python Inference (Transformers)
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "amd/SAND-MathScience-DeepSeek-Qwen32B"
model = AutoModelForCausalLM.from_pretrained(
model_name,
torch_dtype="auto",
device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)
# Example prompt
prompt = "A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost?"
messages = [
{"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
generated_ids = model.generate(
**model_inputs,
max_new_tokens=4096,
temperature=0.7, # Recommended temperature
do_sample=True
)
generated_ids = [
output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print("Response:", response)
```
### Serving (vLLM & SGLang)
You can easily serve this model as an OpenAI-compatible API endpoint.
**Using SGLang:**
```bash
python -m sglang.launch_server --model-path amd/SAND-MathScience-DeepSeek-Qwen32B --max-model-len 32768
```
**Using vLLM:**
```bash
vllm serve amd/SAND-MathScience-DeepSeek-Qwen32B --max-model-len 32768
```

## 💡 Usage Recommendations
To replicate our performance benchmarks and achieve the best reasoning results, we strongly recommend the following configurations:
* **Temperature:** Set `temperature=0.7`. **DO NOT use greedy decoding**, as it can lead to performance degradation and repetitive loops.
* **Prompting:** For mathematical problems, include a directive to enforce structure:
> "Please reason step by step, and put your final answer within \boxed{}."
* **Context Length:** We recommend allowing an output length of **32,768 tokens**. This ensures the model has sufficient space for long Chain-of-Thought (CoT) generation.
* **Thinking Token:** It is recommended to enforce the model to initiate its response with the `\n` token to trigger the reasoning mode effectively.
* **Evaluation:** When benchmarking, conduct multiple passes (Pass@K) and average the results for stability.
