This is a Deepseek distill finetune trained on multilingual Chain-of-Thought (CoT).
When this model is prompted in a language, it will both think and respond in that language, unlike the original R1 which will often think in either Chinese or English.
This will make the outputs of these AIs more understandable and explainable to a wider audience.
Hopefully this will be useful to the AI community, particularly those developing for languages aside from English and Chinese.

This model is a multilingual fine-tuned version of [deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B](https://huggingface.co/deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B).

Other fine-tuned versions of this model can be found in [our collection, here](https://huggingface.co/collections/lightblue/r1-multilingual-679c890166ac0a84e83e38fa).

This model was trained was trained for ~10 minutes on the 8 x L20 instance ([ecs.gn8is-8x.32xlarge](https://www.alibabacloud.com/help/en/ecs/user-guide/gpu-accelerated-compute-optimized-and-vgpu-accelerated-instance-families-1)) on [Alibaba Cloud](https://www.alibabacloud.com/).

# How to use

When using these models, we recommend using a sampling temperature of between 0.5-0.7, [as per the original distilled R1 models](https://huggingface.co/deepseek-ai/DeepSeek-R1-Distill-Qwen-7B#usage-recommendations).

Additionally, we have observed that the model sometimes tends to repeat for more niche languages, so we also recommend setting `repetition_penalty` to 1.1, or higher if the model repeats itself when processing your prompts.

We include scripts to use this model in vLLM:

<ul>
  <li><b>vLLM</b>

Install [vLLM](https://github.com/vllm-project/vllm/) using `pip install vllm`.

<details open>
  <summary>Show vLLM code</summary>
  
```python
from vllm import LLM, SamplingParams

llm = LLM(
    model="lightblue/DeepSeek-R1-Distill-Qwen-7B-Multilingual",
    max_model_len=8_000
)

sampling_params = SamplingParams(
    temperature=0.5, 
    max_tokens=8_000

# <think>
# まず、学校の総生徒数を算出します。各クラスに20人の生徒があり、クラスは3つあるため、総生徒数は60人です。

# 次に、学校全体で男子と女子は同じ人数で分布しています。したがって、男子と女子各有30人。
...
# したがって、3つ目のクラスの男子数は20 - 3 = 17人です。

# Evaluation

Through some quick evaluation of our own, we found this model can produce much correctly formatted and accurate results for higher resource languages, such as Japanese, English, German, than lower resource languages, such as Amharic or Lao.

We did a **very** quick evaluation of 5 questions with each dataset (written by me and translated by GPT4o Mini) on the [lightblue/DeepSeek-R1-Distill-Qwen-7B-Multilingual](https://huggingface.co/lightblue/DeepSeek-R1-Distill-Qwen-7B-Multilingual) model, and we find that the model is able to fairly reliably output the correct answers and in the correct language for a large variety of languages:

For this evaluation, a score of >=0.8 is good, as one of the questions was very hard. The language detection was done using [pycld2](https://pypi.org/project/pycld2/) so errors may occur with the correct language being mistaken for another one.

* There was an error with Farsi detection (my own fault) so we do not report Farsi scores.
