# QuantFactory/SmallThinker-3B-Preview-GGUF
This is quantized version of [PowerInfer/SmallThinker-3B-Preview](https://huggingface.co/PowerInfer/SmallThinker-3B-Preview) created using llama.cpp
# Original Model Card
# SmallThinker-3B-preview
We introduce **SmallThinker-3B-preview**, a new model fine-tuned from the [Qwen2.5-3b-Instruct](https://huggingface.co/Qwen/Qwen2.5-3B-Instruct) model.
## Benchmark Performance
| Model | AIME24 | AMC23 | GAOKAO2024_I | GAOKAO2024_II | MMLU_STEM | AMPS_Hard | math_comp |
|---------|--------|-------|--------------|---------------|-----------|-----------|-----------|
| Qwen2.5-3B-Instruct | 6.67 | 45 | 50 | 35.8 | 59.8 | - | - |
| SmallThinker | 16.667 | 57.5 | 64.2 | 57.1 | 68.2 | 70 | 46.8 |
| GPT-4o | 9.3 | - | - | - | 64.2 | 57 | 50 |
Limitation: Due to SmallThinker's current limitations in instruction following, for math_comp we adopt a more lenient evaluation method where only correct answers are required, without constraining responses to follow the specified AAAAA format.
## Intended Use Cases
SmallThinker is designed for the following use cases:
1. **Edge Deployment:** Its small size makes it ideal for deployment on resource-constrained devices.
2. **Draft Model for QwQ-32B-Preview:** SmallThinker can serve as a fast and efficient draft model for the larger QwQ-32B-Preview model. From my test, in llama.cpp we can get 70% speedup (from 40 tokens/s to 70 tokens/s).
## Training Details
The model was trained using 8 H100 GPUs with a global batch size of 16. The specific configuration is as follows:
```
neat_packing: true
cutoff_len: 16384
per_device_train_batch_size: 2
gradient_accumulation_steps: 1
learning_rate: 1.0e-5
num_train_epochs: 3
lr_scheduler_type: cosine
warmup_ratio: 0.02
bf16: true
ddp_timeout: 180000000
weight_decay: 0.0
```
The SFT (Supervised Fine-Tuning) process was conducted in two phases:
1. First Phase:
- Used only the PowerInfer/QWQ-LONGCOT-500K dataset
- Trained for 1.5 epochs
2. Second Phase:
- Combined training with PowerInfer/QWQ-LONGCOT-500K and PowerInfer/LONGCOT-Refine datasets
- Continued training for an additional 2 epochs
## Limitations & Disclaimer
Please be aware of the following limitations:
* **Language Limitation:** The model has only been trained on English-language datasets, hence its capabilities in other languages are still lacking.
* **Limited Knowledge:** Due to limited SFT data and the model's relatively small scale, its reasoning capabilities are constrained by its knowledge base.
* **Unpredictable Outputs:** The model may produce unexpected outputs due to its size and probabilistic generation paradigm. Users should exercise caution and validate the model's responses.
* **Repetition Issue:** The model tends to repeat itself when answering high-difficulty questions. Please increase the `repetition_penalty` to mitigate this issue.
