Pricing compared
Both keep a free tier. Grok is free at roughly 10 prompts every two hours, with SuperGrok at $30/month (or $300/year) unlocking full Grok 4 and 4.1, a 128K context, DeepSearch and voice — and a SuperGrok Heavy tier at $300/month for the heaviest users. Grok is also bundled into X via X Premium ($8) and Premium+ ($40).
Gemini's free tier runs on Gemini 3 Flash with daily limits and 15GB of storage. Paid plans are Google AI Pro at $19.99/month and Google AI Ultra at $99.99/month, which add the newest models, higher limits, Deep Research and deeper Workspace integration.
Bottom line on price: Gemini's main paid plan ($19.99) undercuts SuperGrok ($30), and Gemini bundles more everyday Google value. Grok is the better deal only if you live on X or want its real-time, candid style.
Models & performance: Grok 4 vs Gemini 3.5
Grok's current generation is Grok 4 and Grok 4.1, with a 128K context, DeepSearch for live research and a "Big Brain" reasoning mode. Gemini's current generation is Gemini 3.5 Pro and 3.5 Flash, with a much larger context window (up to roughly one million tokens) and strong native multimodality across text, images and video.
In day-to-day use both are excellent generalists. Grok stands out for real-time awareness of what's happening on X right now and a more candid, less filtered tone. Gemini stands out for long-context work, research depth and multimodal tasks, plus tight integration with Google tools you may already use. For most questions the quality gap is small; fit depends on which ecosystem and style you prefer.
