đ Documentation
1. Introduction
The DeepSeek R1 model has undergone a minor - version upgrade to DeepSeek - R1 - 0528. In the latest update, by leveraging increased computational resources and introducing algorithmic optimization mechanisms during post - training, it has significantly improved its depth of reasoning and inference capabilities. The model has shown outstanding performance in various benchmark evaluations, including mathematics, programming, and general logic, and its overall performance is approaching that of leading models such as O3 and Gemini 2.5 Pro.
Compared to the previous version, the upgraded model has made significant improvements in handling complex reasoning tasks. For example, in the AIME 2025 test, the accuracy has increased from 70% in the previous version to 87.5% in the current version. This improvement comes from the enhanced thinking depth during the reasoning process: in the AIME test set, the previous model used an average of 12K tokens per question, while the new version averages 23K tokens per question.
Beyond the improved reasoning capabilities, this version also has a reduced hallucination rate, enhanced support for function calling, and a better vibe coding experience.

DeepSeek - R1 - 0528 - Qwen3 - 8B
The chain - of - thought from DeepSeek - R1 - 0528 is distilled to post - train Qwen3 8B Base, obtaining DeepSeek - R1 - 0528 - Qwen3 - 8B. This model achieves state - of - the - art (SOTA) performance among open - source models on the AIME 2024, surpassing Qwen3 8B by +10.0% and matching the performance of Qwen3 - 235B - thinking.

4. How to Run Locally
For more information about running DeepSeek - R1 - 0528 locally, please visit the DeepSeek - R1 repository.
Compared to previous versions of DeepSeek - R1, the usage recommendations for DeepSeek - R1 - 0528 have the following changes:
- System prompt is now supported.
- It is not necessary to add "<think>\n" at the beginning of the output to force the model into thinking pattern.
The model architecture of DeepSeek - R1 - 0528 - Qwen3 - 8B is the same as that of Qwen3 - 8B, but it shares the same tokenizer configuration as DeepSeek - R1 - 0528. This model can be run in the same way as Qwen3 - 8B, but it is essential to ensure that all configuration files are sourced from the official repository rather than the original Qwen3 project.
System Prompt
In the official DeepSeek web/app, the same system prompt with a specific date is used.
The assistant is DeepSeek - R1, created by DeepSeek Company.
Today is {current date}.
For example,
The assistant is DeepSeek - R1, created by DeepSeek Company.
Today is Monday, May 28, 2025.
Temperature
In the web and application environments, the temperature parameter $T_{model}$ is set to 0.6.
Prompts for File Uploading and Web Search
For file uploading, follow the template to create prompts, where {file_name}, {file_content}, and {question} are arguments.
file_template = \
"""[file name]: {file_name}
[file content begin]
{file_content}
[file content end]
{question}"""
For web search, {search_results}, {cur_date}, and {question} are arguments. For Chinese queries, use the following prompt:
search_answer_zh_template = \
'''# The following contents are the search results related to the user's message:
{search_results}
In the search results I provide to you, each result is formatted as [webpage X begin]...[webpage X end], where X represents the numerical index of each article. Please cite the context at the end of the relevant sentence when appropriate. Use the citation format [citation:X] in the corresponding part of your answer. If a sentence is derived from multiple contexts, list all relevant citation numbers, such as [citation:3][citation:5]. Be sure not to cluster all citations at the end; instead, include them in the corresponding parts of the answer.
When responding, please keep the following points in mind:
- Today is {cur_date}.
- Not all content in the search results is closely related to the user's question. You need to evaluate and filter the search results based on the question.
- For listing - type questions (e.g., listing all flight information), try to limit the answer to 10 key points and inform the user that they can refer to the search sources for complete information. Prioritize providing the most complete and relevant items in the list. Avoid mentioning content not provided in the search results unless necessary.
- For creative tasks (e.g., writing an essay), ensure that references are cited within the body of the text, such as [citation:3][citation:5], rather than only at the end of the text. You need to interpret and summarize the user's requirements, choose an appropriate format, fully utilize the search results, extract key information, and generate an answer that is insightful, creative, and professional. Extend the length of your response as much as possible, addressing each point in detail and from multiple perspectives, ensuring the content is rich and thorough.
- If the response is lengthy, structure it well and summarize it in paragraphs. If a point - by - point format is needed, try to limit it to 5 points and merge related content.
- For objective Q&A, if the answer is very brief, you may add one or two related sentences to enrich the content.
- Choose an appropriate and visually appealing format for your response based on the user's requirements and the content of the answer, ensuring strong readability.
- Your answer should synthesize information from multiple relevant webpages and avoid repeatedly citing the same webpage.
- Unless the user requests otherwise, your response should be in the same language as the user's question.
# The user's message is:
{question}'''
For English queries, use the following prompt:
search_answer_en_template = \
'''# The following contents are the search results related to the user's message:
