# 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. |

|
|
|
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 2 additional 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. |
