Frequently Asked Questions

Is DeepSeek safe to use with business data?

DeepSeek is based in China, which raises data privacy concerns for some organizations. For sensitive data, consider using it only for non-confidential tasks or use the open-source model self-hosted.

How does DeepSeek compare to ChatGPT?

DeepSeek matches GPT-4 on reasoning and math benchmarks at a much lower cost. ChatGPT has a better ecosystem (plugins, GPTs, voice) and is more polished for casual use.

Is it really free?

The chat interface is free with generous limits. The API charges per token but at rates 10-50x cheaper than OpenAI.
