Frequently Asked Questions
Is DeepSeek as good as ChatGPT?
On coding and reasoning benchmarks, DeepSeek-R1 is competitive with GPT-4o. For creative writing and open-ended tasks, ChatGPT generally performs better. The biggest difference is that DeepSeek is free, making it a compelling alternative for many use cases.
Is DeepSeek safe to use compared to ChatGPT?
ChatGPT (OpenAI) has stronger enterprise compliance certifications and clear US data residency. DeepSeek stores data on servers in China, which raises data privacy concerns for sensitive business use. For personal use and development, DeepSeek is generally fine. For enterprise compliance-critical tasks, ChatGPT is safer.
Why is DeepSeek cheaper than ChatGPT?
DeepSeek uses a Mixture of Experts (MoE) architecture that activates only the relevant portions of the model per query, dramatically reducing compute costs. This efficiency lets them offer API access at 20-50x lower prices than OpenAI while maintaining competitive quality.
