📚 Documentation

1. Introduction

The DeepSeek R1 model has undergone a minor version upgrade, with the current version being DeepSeek - R1 - 0528. In the latest update, by leveraging increased computational resources and introducing algorithmic optimization mechanisms during post - training, DeepSeek R1 has significantly improved its depth of reasoning and inference capabilities. The model has shown excellent performance in various benchmark evaluations, and its overall performance is approaching that of leading models.

Compared to the previous version, the upgraded model has significant improvements in handling complex reasoning tasks. For example, in the AIME 2025 test, the model’s 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.

2. Evaluation Results

DeepSeek - R1 - 0528

For all our models, the maximum generation length is set to 64K tokens. For benchmarks requiring sampling, we use a temperature of $0.6$, a top - p value of $0.95$, and generate 16 responses per query to estimate pass@1.

Note: We use the Agentless framework to evaluate model performance on SWE - Verified. We only evaluate text - only prompts in HLE testsets. GPT - 4.1 is employed to act as the user role in Tau - bench evaluation.

DeepSeek - R1 - 0528 - Qwen3 - 8B

We distilled the chain - of - thought from DeepSeek - R1 - 0528 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.

3. Chat Website & API Platform

You can chat with DeepSeek - R1 on DeepSeek's official website: chat.deepseek.com, and switch on the button "DeepThink".

We also provide OpenAI - Compatible API at DeepSeek Platform: platform.deepseek.com.

4. How to Run Locally

Please visit [DeepSeek - R1](https://github.com/deepseek - ai/DeepSeek - R1) repository for more information about running DeepSeek - R1 - 0528 locally.

Compared to previous versions of DeepSeek - R1, the usage recommendations for DeepSeek - R1 - 0528 have the following changes:

1. System prompt is supported now.
2. It is not required 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 identical to that of Qwen3 - 8B, but it shares the same tokenizer configuration as DeepSeek - R1 - 0528. This model can be run in the same manner as Qwen3 - 8B.

System Prompt

In the official DeepSeek web/app, we use the same system prompt with a specific date.

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 May 28, 2025, Monday.

Temperature

In our web and application environments, the temperature parameter $T_{model}$ is set to 0.6.

Prompts for File Uploading and Web Search

For file uploading, please 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 query, we use the prompt:

search_answer_zh_template = \
'''# The following contents are the search results based on the user's message:
{search_results}
In the search results I provide to you, each result is in the format of [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 query, we use the prompt:

search_answer_en_template = \
'''# The following contents are the search results related to the user's message:
