The AI race just got a major shake-up. xAI’s Grok 4 is now free for all users, a move announced by Elon Musk only days after OpenAI unveiled GPT-5, its most advanced model yet.
With both launches arriving so close together, the competition between the two AI giants has never been more exciting.
Musk confirmed the news on X, writing:
“Grok 4 is now free for all users. The free tier allows a small number of queries per day. Beyond that requires subscription.”
He also teased a standout feature:
“Long tap on any image and turn it into a video in ~17 seconds.”
That single example sums up Grok 4’s approach: accessible, fast, and fun to use. GPT-5, by contrast, lands as a precision upgrade focused on deeper reasoning, advanced multi-modal capabilities, and professional integrations.
A Comparison of Capabilities
Grok 4 and GPT-5 both bring powerful AI abilities to the table, but they’re built for different audiences and priorities.
Grok 4, available for free with a limit of five queries per day, offers two main interaction modes: Auto Mode for quick, everyday answers and Expert Mode for more complex reasoning. It shines in fast, creative tasks like turning an image into a short video in about 17 seconds, alongside image analysis, casual conversation, and capable coding support.
Paid tiers unlock unlimited use, faster performance, and early access to experimental tools, making them appealing to everyday users, content creators, and hobbyist coders.
GPT-5, meanwhile, is positioned as a premium, professional-grade AI, but it does offer limited free access inside ChatGPT.
Free-tier ChatGPT accounts can send up to 10 messages every 5 hours, and after hitting that limit, chats automatically switch to a lighter “mini” version of the model until the limit resets.
Free-tier users also get one GPT-5 Thinking message per day, which unlocks the model’s most advanced reasoning for a single query.\
For full, unlimited use, GPT-5 is available via ChatGPT Plus and enterprise plans, where it delivers multi-modal reasoning, real-time contextual understanding, and highly personalized responses.
It can handle images, voice, and text in unified sessions, with text-to-video capabilities in beta, and offers robust coding assistance, extended reasoning, plugin access, and deep integration with third-party tools.
Designed with businesses, researchers, and power users in mind, GPT-5 positions itself as the go-to choice for professional-grade AI work.
Two Different strategies
xAI’s decision to drop the paywall for Grok 4 is a clear bid for mass adoption. By letting anyone try the model, even with daily limits, it invites viral use cases and casual experimentation.
OpenAI, meanwhile, is doubling down on premium positioning, keeping GPT-5 as a high-end tool for users who value performance, precision, and integration over free access.
