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.
Grok
Grok is xAI's assistant, tightly integrated into X (Twitter) and known for real-time access to public posts and a less-filtered, more conversational style. The latest Grok 4 and Grok 4 Heavy models are strong at reasoning, and the product includes image generation and voice. Access is bundled with X subscriptions or sold as standalone SuperGrok plans, with a developer API for the Grok model family. Its edge is live X data and personality; its limits are the convoluted subscription tie-in and a smaller ecosystem than the frontier labs.
DeepSeek edges Grok on aggregate — 88 vs 81.
Frontier-class reasoning and coding at rock-bottom prices, with open weights -- held back for Western firms only by China-hosting and compliance concerns. Grok still wins for buyers who prioritise real-time access to public x (twitter) data. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
