DeepSeek
A powerful Chinese AI model that's largely free to use
- Freemium
- New
DeepSeek is an AI model built by a Chinese company, and it became a talking point for one reason: strong performance at very low cost. It demonstrated that results near the top-tier models don’t necessarily require enormous budgets, which shook assumptions across the industry.
What that means for you as a user: excellent performance on coding, math, and logic — free, with generous limits.
What sets it apart
- Strong at coding and math: among the best free options in these two areas specifically
- DeepThink mode: reasons step by step before answering, noticeably improving accuracy on hard problems
- Partly open source: developers can run it locally on their own hardware
- Very cheap API: the cost gap with competitors is large, which matters if you’re building an app
- Fast on ordinary responses
How to use it
- Go to
chat.deepseek.comand create a free account - Type your question or request
- Enable “DeepThink” for tasks needing deeper reasoning (math, complex code, logic)
- Developers: use the API directly from their site at low cost
Who it’s for
A good fit if you’re a developer wanting a strong free assistant, work on math and logic problems, are building an app where cost matters, or want a model you can run locally.
Not a good fit if your work is primarily in Arabic (others are stronger), you handle sensitive or customer data, or you need extras like image generation.
Limits and warnings
Privacy is the key issue here. The company is Chinese and data is stored on its servers, with open questions about its privacy policy and data location. Practical rule: use it for general work and avoid sharing sensitive data, trade secrets, or customer information. This applies to all AI tools, but extra care is warranted here.
Arabic is noticeably weaker than ChatGPT and Gemini.
Content restrictions: it avoids or gives limited answers on politically sensitive topics.
Alternatives
ChatGPT is broader and much stronger in Arabic. Claude is better for code review and deep analysis. Gemini is also free and tied into Google.
✅ Pros
- Very strong writing and coding performance despite being mostly free
- Partially open-source, developers can self-host it
- High response speed
- Very low API cost compared to competitors
❌ Cons
- Arabic support is somewhat weaker than ChatGPT or Gemini
- Some concerns around privacy policy and data storage location
- Less globally known so far
💰 Pricing
| Plan | Price | Features |
|---|---|---|
| Free | $0 | Broad usage via web and app |
| API | Pay as you go | Very low per-token pricing for developers |

❓ Frequently Asked Questions
Is DeepSeek really free?
Yes. Web and app usage is largely free with generous limits, and for developers the API costs far less than competitors — that pricing is what put it on the map in the first place.
Is it safe? I've heard privacy concerns.
This deserves your attention. The company is Chinese and data is stored on its servers, and various governments and organizations have raised questions about its privacy policy and data location. Practical advice: use it for general tasks and don't share sensitive data, trade secrets, or customer information.
How is its Arabic compared to ChatGPT?
Weaker. It understands and writes Arabic, but fluency and linguistic precision fall short of ChatGPT and Gemini. If your work is primarily Arabic, treat it as a second option rather than a first.
What is DeepThink mode?
A mode that makes the model reason step by step before answering. It's slower but noticeably more accurate on math, complex programming, and logic problems. Toggle it below the input box.
Why does everyone talk about it?
Because it showed that performance close to the large models could be reached at far lower training and running costs, which upended a lot of assumptions in the field. Being partly open source also means developers can run it on their own hardware.
