DeepSeek — User Guide
Top-tier Chinese model with strong reasoning; free tier available.
Strengths
- Completely free, no need to pay to use the strongest inference model DeepSeek-R1
- Top-notch mathematics and code reasoning capabilities, comparable to OpenAI o1
- No need to circumvent the wall, direct domestic access, fast speed
- Open source model supports local deployment and secondary development
- Balanced bilingual ability in Chinese and English, especially excellent in understanding Chinese
Best for
- Mathematics problem solving and proof (college entrance examination, competition, college mathematics)
- Code generation, debugging and algorithm problem solving
- Complex logical reasoning and multi-step analysis
- Paper reading and academic content understanding
- Daily Chinese writing, summary and translation
Basic dialogue and reasoning
DeepSeek's reasoning mode (R1) will show the complete thinking process and is very suitable for tasks that require rigorous derivation.
Scenario
Use deep thinking mode to solve complex math problems
Prompt example
Please use deep thinking mode to answer the following questions: Prove: For any positive integer n, n³ - n is divisible by 6.
Output / what to expect
DeepSeek R1 will display the complete inference chain:
- Factor n³ - n into n(n-1)(n+1)
- Show that this is the product of three consecutive integers
- Prove that it must contain multiples of 2 and multiples of 3
- therefore divisible by 6 The thinking process is transparent and logical.
Tips
Click the "Deep Thinking" button to enable R1 mode, which is suitable for scenarios that require strict reasoning such as mathematical proofs and logical derivation.
Scenario
Comparative analysis of two technical solutions
Prompt example
I need to choose a caching solution for a web application with 100,000 daily users. Please compare and analyze: Option A: Redis cluster Option B: Local memory cache (such as Caffeine) Analyze and give recommendations from the four dimensions of performance, cost, operation and maintenance complexity, and data consistency.
Output / what to expect
DeepSeek will provide a structured four-dimensional comparative analysis table and comprehensively consider the daily activity scale.
Recommend the Redis cluster solution and explain in which scenarios local caching is more suitable.
Tips
By providing specific business scale and constraints, DeepSeek's analysis will be more targeted.
