MAI-DS-R1 – An AI model open-sourced by Microsoft, based on an improved version of DeepSeek R1

What is MAI-DS-R1?

MAI-DS-R1 is an AI model developed by Microsoft, based on the improved version of DeepSeek R1. MAI-DS-R1 is optimized using post-training techniques and supports responding to 99.3% of sensitive topic prompts, doubling the performance of the original version and reducing harmful content risks by 50%. MAI-DS-R1 maintains the same level of inference capability as DeepSeek R1, supports multilingual responses, and is suitable for multilingual environments such as international organizations, multinational enterprises, and educational institutions. MAI-DS-R1 has been open-sourced for researchers and developers to use.

Main Features of MAI-DS-R1

1. Efficient Response to Sensitive Topics: Supports answering 99.3% of sensitive questions, significantly outperforming the original DeepSeek R1.

2. Low Risk: In security assessments, the risk of harmful content is reduced by 50%.

3. Inference Capability: Maintains the same inference ability as DeepSeek R1, suitable for complex logic and knowledge-based questions.

4. Multilingual Support: Supports multiple languages to meet the needs of different linguistic environments.

Technical Principles of MAI-DS-R1

• Post-Training: Optimizes the original DeepSeek R1 model using post-training techniques. Post-training involves further fine-tuning the model after pre-training using specific datasets and strategies to enhance its performance on particular tasks. Microsoft used around 350,000 examples of blocked topics for post-training, covering a wide range of sensitive topics. MAI-DS-R1 learned how to respond more effectively to these topics, avoiding the generation of harmful content.

• Data Augmentation: During post-training, Microsoft added 110,000 security and violation examples from the Tulu3 SFT dataset, including content such as CoCoNot, WildJailbreak, and WildGuardMix. These examples help the model better identify and handle potential harmful content.

• Multilingual Translation: During post-training, questions were translated into various languages to meet the needs of different linguistic environments. This enhanced the model’s multilingual capabilities and its ability to understand questions in diverse cultural contexts.

• Security Assessment: Microsoft conducted comprehensive security assessments on MAI-DS-R1, using the HarmBench dataset to detect harmful content in the model’s generated output. This ensures that the output complies with ethical and legal standards.
