DeepSeek is a Chinese AI company that has shaken up the industry with remarkably cost-effective models. Their DeepSeek V3 delivers GPT-4 level performance at a fraction of the cost, while DeepSeek R1 rivals Claude and OpenAI's reasoning models. The API is OpenAI-compatible, making migration trivially easy. DeepSeek made headlines in January 2026 when they released R1 and open-sourced both the model weights and training methodology.

Frequently Asked Questions
Is DeepSeek API compatible with OpenAI SDK?
Yes, 100% compatible. Just change the base_url to 'https://api.deepseek.com' and your API key. All your existing OpenAI code will work.
How much cheaper is DeepSeek than GPT-4?
DeepSeek V3 is about 10-20x cheaper than GPT-4 Turbo. Input tokens cost $0.27/M vs GPT-4's $3/M. This makes it extremely cost-effective for high-volume applications.
Can I self-host DeepSeek models?
Yes. DeepSeek has open-sourced model weights for V3 and R1 under permissive licenses. You can run them locally with vLLM or other inference engines if you have sufficient GPU memory.
Is DeepSeek safe to use for sensitive data?
This depends on your requirements. DeepSeek is a Chinese company, so data may be subject to Chinese data laws. For sensitive applications, consider self-hosting the open-source weights instead of using the API.
