Full review →What is DeepSeek?
DeepSeek is a Chinese AI company producing open-source language models that compete with GPT-4 and Claude at a fraction of the price. DeepSeek V4, released in March 2026, scores 81% on SWE-bench Verified and supports a 1M-token context window. The chat interface at chat.deepseek.com is completely free with no usage limits. API pricing starts at just $0.30 per million input tokens and $0.50 per million output tokens for V4, with cache hits dropping input cost to $0.03 per million tokens. DeepSeek R1 is the dedicated reasoning model for complex math, science, and logic tasks. Models are fully open-weight, meaning developers can download and self-host them for complete data privacy. Available through major cloud providers including Together AI, Fireworks, Azure, and AWS Bedrock. The primary trade-offs are API reliability during peak hours, a smaller developer ecosystem compared to OpenAI, and regulatory considerations for organizations in sensitive industries due to the company being based in China.
