Overview
DeepSeek is China's open-source value king. DeepSeek-V3 and R1 (reasoning model) match closed-source frontier models at a fraction of training cost, with open weights and free web/app access. API pricing is roughly 1/10 of GPT-4o, shaking the global industry. Supports web search, deep reasoning (R1's chain-of-thought is visible) and code generation. Best for free daily personal use, low-cost developer API calls and enterprise self-hosting (open-source, commercial-friendly). Strengths: completely free, excellent Chinese, frontier-level reasoning, open weights. Weaknesses: multimodal (image/video) not yet available; occasional rate limiting during peak.
