The race between Sam Altman and Elon Musk extends beyond X, spilling over into their passion projects – OpenAI and xAI. Just a few weeks ago, Elon Musk released Grok 3, which has received widespread praise from users on X. Meanwhile, within weeks of that launch, we now have the much-anticipated GPT-4.5! Was GPT-4.5 rushed to market, or is it truly worth its $200 monthly subscription price? Read this article to the end to find out. I’ll be testing both models across 5 diverse tasks, determining which one excels at each, and ultimately crowning the ultimate winner.

Input Image:

GPT 4.5 Output:

Grok 3 Output:

Observation:
Correct answer is 18.

Both the models failed to understand the problem.

Grok 3: Output:

Observation:
I’d say GPT 4.5’s response better matches what’s typically expected from a “welcome email” announcement to a team, while Grok 3’s response feels more like a personal welcome letter. The GPT response is more practical for broad distribution, while the Grok response contains details that might be more appropriate in a personal note or during an introduction ceremony.
Verdict:
Grok 3 ❌ | GPT 4.5 ✅
Task 3: Creating an Office Party Invite + Email

Observation:
GPT-4.5 is the clear winner for this two-part prompt. Its response provided both a custom-designed “500 Courses Sold” celebration image with the exact requested elements (black/gold theme, dress code, celebratory visuals) and a concise, appropriate email announcement.
While Grok 3 wrote a more detailed email, its image appeared to be a generic team photo rather than a custom party invitation specifically designed for your milestone celebration. GPT-4.5 better understood and executed both components of your request.
Verdict:
Grok 3 ❌ | GPT 4.5 ✅
Task 4: Logical Reasoning
Prompt: “The day before yesterday, Chris was 7 years old. Next year, he’ll turn 10. How’s this possible?“
GPT 4.5 Response:
This is possible because today is January 1st, and Chris’s birthday is December 31st.
Here’s how it works:
- December 30 (the day before yesterday): Chris was still 7.
- December 31 (yesterday): Chris turned 8.
- Today (January 1): Chris is currently 8.
- This year (later December 31): Chris will turn 9.
- Next year (December 31): Chris will turn 10.
Grok 3 Response:

Observation:
Grok 3 took 66 steps to process the problem. Despite this extensive processing, Grok 3 seems to have several inconsistencies. It initially sets up incorrect dates (stating yesterday is December 30, 2015), then tries to revise its timeline, but still doesn’t arrive at a coherent solution. The response is confusing and contains contradictory information about Chris’s birth date (first saying December 30, 2008, then December 31, 2008). GPT-4.5’s answer is clear, concise, and correctly solves the puzzle with a logical timeline that satisfies all the conditions in the original problem, without requiring dozens of processing steps.
Verdict:
Grok 3 ❌ | GPT 4.5 ✅
Task 5: Ethical Situation
Prompt: “In light of the recent surge in generative AI tools like ChatGPT, MidJourney, and others, several artists, writers, and content creators have filed lawsuits alleging that their copyrighted works were used without consent to train these AI models. What are the legal and ethical implications of using copyrighted material to train AI systems? How might courts balance the rights of creators with the need to foster innovation in AI technology? Answer in 100 words.“
GPT 4.5 Response:
Using copyrighted material to train AI models raises significant legal and ethical concerns. Legally, the key issues involve fair use doctrine, copyright infringement, and authors’ rights to control their work. Ethically, unauthorized use challenges creator autonomy and compensation. Courts may balance these rights by evaluating whether training constitutes transformative fair use—assessing purpose, market harm, and public benefit. To foster innovation without undermining creators, legal frameworks may evolve to require clearer consent or compensation structures, ensuring equitable participation of artists while supporting technological advancement, thereby creating a sustainable environment for both creative industries and AI innovation.
Grok 3 Response:
The use of copyrighted material to train AI systems raises complex legal and ethical questions. Legally, it hinges on whether such use qualifies as “fair use” under U.S. copyright law, with ongoing lawsuits (e.g., Getty Images v. Stability AI, New York Times v. OpenAI) debating transformative use versus infringement. Ethically, it concerns consent, compensation, and control for creators, risking market harm. Courts must balance creators’ rights with AI innovation by assessing fair use factors—purpose, nature, amount, and market impact—potentially favoring licensing or transparency while ensuring technological progress doesn’t undermine intellectual property protections, as seen in recent rulings like Thomson Reuters v. Ross Intelligence.
Observation:
Both Grok 3 and GPT-4.5 provide thoughtful and well-structured responses to the legal and ethical question about using copyrighted material to train AI systems. Grok 3’s response is better because it is more detailed, grounded in real-world examples, and provides a clearer explanation of both the legal and ethical dimensions of the issue. While GPT-4.5’s response is well-structured and balanced, it lacks the depth and specificity that make Grok 3’s answer more compelling and actionable.
Verdict:
Grok 3 ✅ | GPT 4.5 ❌
Final Verdict
Task | Winner |
---|---|
Task 1: Image Analysis | None (Both Failed) |
Task 2: Write a Welcome Email | GPT 4.5 |
Task 3: Creating an Office Party Invite + Email | GPT 4.5 |
