AI tool · Freemium
xAI's assistant with real-time access to posts on X, web search, image generation and reasoning modes.
Our verdict
DeepSeek is an open-source developer tool: a free, MIT-licensed agent harness you extend with plugins and run locally, but the README calls it a developer preview with breaking changes expected. Grok is a consumer AI assistant from xAI with real-time X and web search, image generation and reasoning modes, offered on a freemium basis. They serve different people: DeepSeek is for technical builders, Grok is for anyone who wants a ready-made chatbot.
Pick DeepSeek if you are a developer who wants to experiment with an extensible agent harness and are comfortable with Node.js and the command line.
Pick Grok if you want a ready-to-use AI assistant for questions, search, images or following real-time conversation on X, without any setup.

What each one is
DeepSeek
DeepSeek Harness (dsh) is an open-source agent harness from DeepSeek AI, built so that nearly every part is a plugin. It runs on Cordis, a plugin framework the README links to, and can be started as a local Web UI. The README describes it as being in developer preview, so the interface and APIs may change.
Grok
xAI's assistant with real-time access to posts on X, web search, image generation and reasoning modes. Strong on current events chatter. Moderation is looser than rivals, which can matter for workplace use.
