Is DeepSeek better than ChatGPT for coding?

DeepSeek R1 excels at complex algorithmic reasoning and math problems, while ChatGPT-4o is superior for general code, documentation, and multimodal tasks. DeepSeek is often 10x cheaper, ideal for intensive use.

DeepSeek R1 is an open-source AI model developed by Chinese company DeepSeek, launched in January 2025. It rivals GPT-4 on benchmarks while being significantly cheaper and fully transparent in its architecture.

Can DeepSeek replace GitHub Copilot?

DeepSeek can handle complex code generation tasks but lacks native IDE integration. For real-time autocomplete, GitHub Copilot remains superior. However, DeepSeek excels at architectural decisions and debugging complex logic.

DeepSeek offers a free tier with limited requests. Its API costs about $0.14/million input tokens vs ChatGPT's $2.50, approximately 18x cheaper for high-volume applications.

Which AI writes the best Python code?

Both excel at Python. ChatGPT-4o produces cleaner, more idiomatic code with better documentation. DeepSeek R1 handles complex algorithms and mathematical calculations with greater precision, especially for data science.
