Frequently asked questions
Is DeepSeek actually free to use?
Yes, the web chat and mobile app are free with no subscription required. API usage is billed per token, but rates are considerably lower than most major competitors.
How does DeepSeek R1 compare to ChatGPT or Claude?
On coding and multi-step reasoning benchmarks, R1 scores comparably to GPT-4 class models. For general creative writing and nuanced instruction-following, ChatGPT and Claude still have an edge in consistency.
Is it safe to use DeepSeek for private or business content?
DeepSeek's servers are operated in China, and its privacy policy reflects Chinese data laws. For sensitive client work or confidential business content, self-hosting the open-source weights is the safer route.
Can I use DeepSeek models without sending data to DeepSeek servers?
Yes. The model weights are publicly available and can be run locally or on your own cloud infrastructure, giving you full control over your data.
What is the DeepSeek API price compared to OpenAI?
DeepSeek API pricing is substantially lower per million tokens than OpenAI's GPT-4o, making it attractive for creators building AI-powered tools on a tight budget. Verify current rates on deepseek.com before committing.
Does DeepSeek have image or video generation features?
No. DeepSeek focuses on text and code. For image or video generation you would need a separate tool.
