Grok 4 by xAI in 2026: The Most Honest AI Review After 30 Days of Daily Use
Grok 4 by xAI in 2025: The Most Honest AI Review After 30 Days of Daily Use
I’ve been testing AI models since the early ChatGPT-3 days. In 2025 alone, I actively used Claude 3.5 Sonnet, Gemini 2.0 Flash, GPT-4o — and now, Grok 4 by xAI.
Elon Musk describes Grok as “maximally truth-seeking.” But does it actually deliver? Let’s break it down.
What Exactly Is Grok 4 in 2025?
Grok 4 is xAI’s flagship large language model, quietly launched in late 2024 and significantly upgraded throughout 2025. Unlike many competitors, Grok is built from scratch and trained on a massive cluster of over 100,000 Nvidia H100 GPUs.
xAI’s mission is bold: help humanity understand the universe — without excessive corporate censorship.
How to Access Grok 4 (November 2025)
- Free Tier: Grok 3 with limited queries on grok.com, x.com, and mobile apps
- Grok 4 Access: X Premium+ ($40–60/month) or SuperGrok subscription
- Voice Mode: Available on iOS & Android (surprisingly good multilingual support)

My 30-Day Real-World Testing
1. Coding Test
Grok 4 generated a complete Tailwind + React SaaS landing page in one shot. Clean code, dark mode, SEO tags — deployed live in under 20 minutes.
2. Research Test
I shared 47 quantum computing research papers. Grok summarized them into a structured 12-page report with citations and contradictions. Claude refused half of them.
3. Sensitive Topics
Grok answered controversial questions directly, fact-based, without lecturing or moralizing.
4. Image Generation
The image quality often matched or exceeded Midjourney V6 — coherent, cinematic, and uncensored.
5. Humor Test
Me: “Roast me. I use Windows 11.”
Grok 4: “You’re the reason Microsoft thinks Clippy deserves a comeback.”
The Good
- No corporate preaching
- True real-time data access
- Excellent humor & personality
- Top-tier image generation
- Fastest response time I’ve used
- Deep understanding of internet culture
The Not-So-Good
- Can be too edgy without guidance
- More expensive than ChatGPT Plus
- No advanced plugins yet
- Voice mode limited to mobile
Who Should Use Grok 4?
- Developers & researchers
- Writers who hate censorship
- Creators needing real-time info
- Anyone tired of “I can’t do that”
Final Verdict: ⭐ 9.4 / 10
I still use ChatGPT for corporate tasks and Claude for ultra-long documents. But for everything else — Grok 4 wins.
If you’re still using 2024-era models in late 2025, you’re missing a major shift.
