lightblue/DeepSeek-R1-Distill-Qwen-1.5B-Multilingual

R1 m u l t i l i n g

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.

Other fine-tuned versions of this model can be found in our collection, here.

This model was trained was trained for ~10 minutes on the 8 x L20 instance (ecs.gn8is-8x.32xlarge) on Alibaba Cloud.

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.

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:

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 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 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.
