DeepSeek
DeepSeek is the Chinese lab that upended AI pricing with frontier-class reasoning and coding models at a fraction of Western costs. Its consumer chat app is free, and the DeepSeek API is among the cheapest anywhere, with an OpenAI-compatible interface and open-weight model releases developers can self-host. Models in its V-series and reasoning line are genuinely strong on math, code, and logic. The trade-off is China jurisdiction and data-governance concerns that matter for Western businesses.
