The same prompting skills apply — give context, a role, a clear task, and the format you want. See [how to write a good AI prompt](/blog/how-to-write-a-prompt). And as with any model, it can be confidently wrong, so [verify important claims](/blog/spot-ai-hallucinations). ## What to consider before using DeepSeek One practical note: DeepSeek is built by a China-based company, and some employers, schools, and governments restrict tools based on where data is processed. **Before using it for sensitive or work data, check your organization's policy** — the same caution applies to any AI tool.
