Libraries

How to use Tiiny/SmallThinker-3B-Preview with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

	# 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.

	Now you can directly deploy SmallThinker On your phones with [PowerServe](https://github.com/powerserve-project/PowerServe).

	## 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:

	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
	```
	### model
	model_name_or_path: /home/syx/Qwen2.5-3B-Instruct

	### method
	stage: sft
	do_train: true
	finetuning_type: full
	deepspeed: examples/deepspeed/ds_z3_config.json

	### dataset
	dataset: o1-v2
	template: qwen
	neat_packing: true
	cutoff_len: 16384
	overwrite_cache: true
	preprocessing_num_workers: 16

	### output
	output_dir: saves/qwen2-01-qat/full/sft
	logging_steps: 1
	save_steps: 1000
	plot_loss: true
	overwrite_output_dir: true
	```
	2. Second Phase:
	- Combined training with PowerInfer/QWQ-LONGCOT-500K and PowerInfer/LONGCOT-Refine datasets
	- Continued training for 2 additional epochs
	```
	### model
	model_name_or_path: saves/qwen2-01-qat/full/sft/checkpoint-24000

	### method
	stage: sft
	do_train: true
	finetuning_type: full
	deepspeed: examples/deepspeed/ds_z3_config.json

	### dataset
	dataset: o1-v2, o1-v3
	template: qwen
	neat_packing: true
	cutoff_len: 16384
	overwrite_cache: true
	preprocessing_num_workers: 16

	### output
	output_dir: saves/qwen2-01-qat/full/sft
	logging_steps: 1
	save_steps: 1000
	plot_loss: true
	overwrite_output_dir: true
	```

	## 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.
