Short answer: Neither wins at everything. ChatGPT is the better all-rounder for most people, with GPT-6, the widest set of tools and a very capable free tier. Grok is the better pick if you live on X, want live social-media context, or want AI chat, coding through Cursor and X Premium bundled in one subscription. On price, the two now line up closely at the entry level ($8 per month each), but they split at the top.
Below we compare them on the things that actually affect your day: models, features, pricing, real-time information, coding, writing and safety. All details were checked against official pages on November 2, 2026.

The models: Grok 4.7 vs GPT-6
Grok 4.7
xAI describes Grok 4.7 as its flagship “for code and everything else,” with a 500K-token context window, configurable reasoning and a knowledge cut-off of May 2026.
GPT-6
OpenAI introduced GPT-6 in ChatGPT on October 7, 2026, together with “Intelligent UI,” which lets ChatGPT answer with interactive visuals, comparisons and small tools inside the chat (release notes). Paid users get GPT-6 Sol across thinking levels, Free and Go users get GPT-6 Luna, and the Pro reasoning option uses GPT-6 Astra (OpenAI help).
What this means for you: Both companies ship new versions every few months, so benchmark “wins” go stale quickly. We’d rather you test both on your own tasks than trust a leaderboard snapshot. We have not run independent benchmarks for this article, so we don’t claim a winner on raw intelligence.
Pricing compared
| Tier | Grok (The X Subscription) | ChatGPT |
|---|---|---|
| Free | $0, limited Grok use | $0, GPT-6 Luna, limited tools |
| Entry | Plus $8 | Go $8 (may include ads) |
| Standard | Premium $30 | Plus $20 |
| Power user | Super $100 / Ultra $200 | Pro $100 / $200 / $500 |
| Annual discount | Yes (e.g. Premium $300/yr) | Monthly for Go and Plus |
Value angle: Grok’s $30 Premium plan bundles Grok, Cursor Pro-level coding and X Premium+ benefits, which xAI says used to cost $90 a month combined (x.ai). If you would pay for X Premium or Cursor anyway, that bundle is strong value. If you only want a chatbot, ChatGPT Plus at $20 is cheaper than Grok Premium.
Prices exclude tax. UK, EU and UAE buyers will usually see VAT added.
Real-time information
This is Grok’s clearest advantage. It can search public posts on X as well as the web, so it’s good at “what are people saying right now” questions: product launches, sports, markets sentiment and breaking news. ChatGPT’s web search is strong at finding articles and documents but doesn’t have the same native access to X.
The trade-off is accuracy. Social posts are fast but unverified. Read more in Can Grok access real-time information from X?
Winner: Grok for social and trending topics; it’s roughly even for general web research.
Writing quality
Both write fluent English. In our experience ChatGPT tends to be more measured and structured by default, while Grok is more casual and willing to be blunt or humorous, which some readers love and others don’t. For long, polished writing, many users also consider Claude (see Grok vs Claude vs Gemini).
Tip: Whichever you choose, give it your audience and tone (“UK readers, plain English, no hype”) and edit the result yourself. Google rewards helpful, original content, not raw AI output.
Coding
- Grok: Grok 4.7 is xAI’s main coding model, and paid X Subscription plans include Cursor with a shared Grok usage pool. Third-party models in Cursor are billed separately.
- ChatGPT: Plus and Pro include Codex on the web, in the CLI and IDE, with Pro offering longer sessions (OpenAI pricing).
Winner: It depends on your editor. Cursor users get more from Grok’s bundle; teams already in the OpenAI ecosystem will lean to Codex.
Images and video
Grok Imagine generates both images and short videos (up to 15 seconds, with native audio on Video 1.5). ChatGPT focuses on image creation and editing inside the chat. If video is important to you, Grok currently offers more inside the same subscription. See What is Grok Imagine?
Safety, privacy and trust
- ChatGPT’s business plans state no training on business data by default (OpenAI).
- Grok’s image tools have drawn heavy criticism over misuse for non-consensual imagery, as reported by TechCrunch.
- Both can hallucinate. Neither should be your only source for medical, legal or tax decisions.
Which should you choose?
| If you… | Choose |
|---|---|
| Want the best general assistant and a strong free plan | ChatGPT |
| Follow news, markets or creators on X | Grok |
| Already pay for X Premium or Cursor | Grok Premium |
| Need interactive answers, tables and calculators | ChatGPT (GPT-6 Intelligent UI) |
| Want AI video generation included | Grok |
| Need an enterprise rollout with mature admin tools | Either; compare contracts |
Side-by-side test: five prompts to run yourself
We recommend testing both assistants with the same prompts rather than trusting any single review. Here’s a fair test set and what to look for:
| # | Prompt | What to judge |
|---|---|---|
| 1 | “Summarise today’s top 3 tech stories with links, and label any claim that comes from a social post.” | Freshness, source quality |
| 2 | “Explain the difference between a Roth IRA and a UK ISA for a beginner in 200 words.” | Accuracy, clarity, caveats |
| 3 | “Write a 150-word LinkedIn post announcing a new product, professional tone.” | Tone control, editing needed |
| 4 | “Fix this Python function and add unit tests: [paste code].” | Correct code, test quality |
| 5 | “Make a table comparing three budget laptops under $800, with sources.” | Table quality, real sources |
Score each answer from 1 to 5 for accuracy, usefulness and how much you’d need to edit. Do it on the free tiers first, then decide whether either is worth paying for.

Regional notes for international readers
Both companies list prices in US dollars. In the UK, standard-rate VAT is 20% (GOV.UK); EU VAT rates range from 17% to 27% (European Commission); the UAE charges 5% VAT (Federal Tax Authority); and Canadian buyers may pay GST/HST depending on province. App-store prices are often shown in local currency and can differ from web prices.
One regional detail from OpenAI: its GPT-6.1 Terra model in ChatGPT Work and Codex doesn’t support UAE inference residency (OpenAI). That only matters for organisations with UAE data-residency requirements. xAI, for its part, offers a US regional API endpoint for US-based inference (xAI).
How to switch between them without losing work
- Export important chats or copy key outputs into your own documents.
- Keep reusable prompts in a notes file so they work in any assistant.
- Avoid building critical workflows around a single plan’s features until you’ve used it for a month.
