Grok 3 is Free: 5 Things We Tested on Elon Musk’s AI Chatbot

Elon Musk’s AI company, xAI, has launched Grok 3, its most advanced AI model yet. Dubbed "the world's smartest AI," Grok 3 is now free for users to try. This latest version is built on a super-powerful cluster of 100,000 Nvidia Hopper GPUs, making it a major competitor to OpenAI’s ChatGPT.

According to xAI, Grok 3 excels at reasoning, coding, mathematics, and general knowledge. With enhanced deep-search capabilities and improved AI reasoning, this chatbot is designed to deliver detailed and accurate responses while engaging in human-like thinking processes.

We tested Grok 3 in various scenarios, from research and image generation to coding and data analysis. Here’s what we found!

1. First Impressions: A Familiar Yet Powerful Interface

When you first open Grok 3, the interface looks very similar to ChatGPT and DeepSeek-R1. The input bar is in the center, with options like Attach File, DeepSearch, and Think on the left and an AI model picker on the right.

Key Features at a Glance:

. Temporary Chat Mode: A privacy-focused option where chats are auto-deleted within 30 days.
. Multi-Functionality: Research, Brainstorm, Analyze Data, Create Images, and Code—all within one chat window.
. Web Search Enabled: Users can toggle the "Enable Search" option to allow the AI to fetch real-time information.
. Switch Between Models: Users can compare responses from Grok 2 and Grok 3.

Overall, the interface is clean, user-friendly, and optimized for deep reasoning—a major upgrade from previous versions.

2. Research Capabilities: DeepSearch in Action

One of the standout features of Grok 3 is DeepSearch, which mimics human-like thinking while analyzing vast sources of data.

To test this, we asked:
"What is the state of the house sparrow species in India?"

Within 46 seconds, Grok 3 scanned 101 sources and compiled a detailed report, including:
. Conservation status
. Causes of population decline
. Legal framework protecting the species
. References & citations for credibility

Unlike basic AI responses, Grok 3 engaged in self-talk and evaluation, refining its answer dynamically—something usually seen in humans while reasoning through a problem.

Verdict: DeepSearch is a game-changer for researchers, students, and knowledge seekers who need well-structured, in-depth answers rather than simple text-based replies.

3. Image Generation: Hyperrealistic, But Not Perfect

Grok 3 offers AI-generated images with customization options at the bottom. Users can generate four variations at a time and refine them based on their needs.

To test its image capabilities, we uploaded a vintage Malayalam movie poster (“Sreekrishnapurathe Nakshathrathilakkam”).

Result? Grok 3 correctly identified the language but failed to recognize the movie title. Instead, it misread it as “Anandapurathu Vaykk”—a nonsensical phrase.

Next, we uploaded an old Macintosh SE computer image. This time, Grok 3 correctly identified it and even provided detailed historical information about the model, processor, and release years.

Verdict: Grok 3 excels in image generation but still struggles with complex image analysis, especially with non-English text or intricate visuals.

4. Coding & Data Analysis: Smart, Fast & Efficient

Grok 3 is built to assist programmers and analyze data, making it useful for professionals.

To test its coding skills, we gave it a Python coding task:
"Write a Python script to calculate the Fibonacci sequence up to 100 terms."

Within seconds, Grok 3 generated a clean, optimized script:
