DeepSeek is a Chinese AI lab that gained global attention for its open-source R1 reasoning model, which rivals GPT-4 class performance at a fraction of the cost. The DeepSeek API is OpenAI-compatible, making integration straightforward for developers already using OpenAI. Pricing starts at $0.28 per million input tokens — up to 95% cheaper than comparable Western models. The deepseek-reasoner model excels at math, coding, and logical reasoning tasks. Widely used by cost-conscious developers and teams exploring Chinese AI alternatives.

Frequently Asked Questions
DeepSeek is one of the most affordable frontier model APIs. DeepSeek-V3 costs $0.27 per million input tokens and $1.10 per million output tokens u2014 over 90% cheaper than GPT-4o. The deepseek-reasoner model (R1) costs $0.55/$2.19 per million tokens, still dramatically cheaper than OpenAI o1.
Yes. The DeepSeek API uses an OpenAI-compatible interface. You can use the official OpenAI Python or Node.js SDK with DeepSeek by changing the base URL to api.deepseek.com and your API key. Most OpenAI code works with DeepSeek with minimal changes.
DeepSeek is a Chinese company and its data handling practices differ from US/EU providers. Enterprise users should review DeepSeek's privacy policy carefully. For applications involving sensitive data, consider using the open-source DeepSeek R1 model self-hosted, or routing through a provider that offers data residency guarantees.
DeepSeek R1 performs comparably to OpenAI o1 on most reasoning benchmarks including math (AIME), coding (Codeforces), and scientific reasoning (GPQA). Independent evaluations show R1 matching or exceeding o1 on several benchmarks at a fraction of the cost. It is a genuine breakthrough for open-weight reasoning models.
