What is DeepSeek?
DeepSeek is a top-notch large-scale domestic model launched by DeepSeek. It provides two versions: V3 (universal dialogue) and R1 (deep reasoning). It is completely free to use on the web page. Suitable for developers, researchers and ordinary users who require high-quality Chinese understanding, code generation and complex reasoning.
Core Features
- DeepSeek-V3: Powerful universal dialogue and multi-round interaction capabilities
- DeepSeek-R1: Slow thinking and deep reasoning, suitable for mathematics, logic, and code problems
- Code generation and debugging, supporting mainstream programming languages
- Search online and get real-time information
- File upload and long document understanding (supports PDF and other formats)
Pricing Plans
The web page (chat.deepseek.com) is completely free and no payment is required; API calls are billed by token, and the R1 model is about $0.55/$2.19 per million tokens (input/output).
Pros
- Completely free, no limit on usage (web version)
- Outstanding reasoning ability, R1 model is comparable to GPT-4o in the fields of mathematics and programming
- Excellent Chinese understanding and generation quality, good localization experience
Cons
- The server is busy during peak periods and the response speed is unstable.
- Multimodal capabilities (image understanding) are not yet as good as GPT-4o and Gemini
- Web search integration is less deep than dedicated search AI like Perplexity
DeepSeek was developed by Hangzhou DeepSeek. Its DeepSeek-R1 model relies on reinforcement learning training solutions to reach the top international levels in benchmark tests such as mathematical reasoning and code generation. The training cost is much lower than similar models, attracting global attention.
