Grok 4.1 Freemium

Grok 4.1 is xAI’s late-2025 update to Grok 4. The pitch this time is not raw benchmark score but tone: xAI retrained the model on style and emotional cues, and it now reads social context better than Grok 4 did.

What is Grok 4.1?

It is a chat and reasoning model available in the Grok app on the web and mobile, plus the xAI API. Two variants ship: a fast standard mode and a thinking mode for harder problems. The distinguishing feature remains live search across X posts, which no other major assistant has.

xAI lists hallucination rates materially lower than Grok 4 on factual queries, though independent testing on that claim is still thin.

What are Grok 4.1’s main features?

• Live X search: pulls current posts and trends into answers.
• Emotional reasoning: reads tone and subtext in conversations more accurately.
• Creative writing: noticeably better at fiction and voice-driven copy than Grok 4.
• Thinking mode: step-by-step reasoning for math and analysis.
• Image and vision: accepts images and generates them in the app.

Product Highlights

• X integration is the real differentiator if your work involves social monitoring.
• The unfiltered reputation cuts both ways; brand-safety teams often block it.
• Free tier exists with daily message caps; SuperGrok is $30/month.
