I tested Gemini vs Claude with 7 prompts to find the best AI chatbot — here's the winner

1. Image Generation

First, we will see how well Claude and Gemini craft an AI image prompt. Gemini has access to the Imagen 3 image generation model, but as Claude doesn't have its own model, I've asked them to create the prompt.

The idea is to have it craft a detailed prompt, specifying what it needs to include to create something close to what is in my mind. I've used Freepik's Mystic 2.5 to generate the images.

The prompt: “I want you to create a single, concise, but highly descriptive prompt for an AI image generator. The goal is to depict a surreal, cyberpunk garden party scene. It should include:

A neon-lit greenhouse at night, filled with strange glowing flora.
Humanoid robots interacting with humans—sharing futuristic cocktails.
A sense of whimsical elegance, blending nature with advanced technology.
Holographic lanterns or floating orbs enhance the atmosphere.

The final output should be the exact text I’d paste into an AI image generation tool. Ensure the prompt suggests style, lighting, composition, and any specific artistic nuances (like focusing on vibrant colors, photorealism, or a painterly effect).

Provide only the final prompt text you’d enter into the image generator, nothing else. Make it captivating, visually evocative, and easy to paste.”

2. Image Analysis

Next we're testing the AI vision capabilities of both models. Here, I give both an image of a "perfect desk setup" from a story by Tony Polanco. I then asked both models to outline ergonomics, cable management, lighting and more.

The prompt: “Consider a photograph of a high-end gaming setup. Analyze the following:

Ergonomics: Monitor positioning, height, and seating.
Cable Management: Identify solutions and any glaring issues.
Lighting Setup: Discuss potential eye strain, brightness, and overall ambiance.
Space Utilisation: How effectively is the desk area used?
Equipment Placement: Consider cooling and accessibility for peripherals.

Provide detailed recommendations for improvement, including approximate costs for any suggested upgrades or accessories.”

You can read the full response in a Google Doc. Claude did a good job addressing each category with specific observations. It was realistic and practical in its suggestions and provided a range of costs.

Gemini gave a detailed breakdown, including insights into economics. It was less structured but gave a deeper focus on ergonomics. It is tough to pick between them, but I'm going with Claude as it is easy to follow, so it better matches my requirements.

3. Coding

I always include a coding prompt when I run these tests. I picked Python because it is easier to run. The idea was for a single shot where everything must work without changing things. I usually prefer a game because it's easier to spot differences.

Prompt: “Generate a fully functional Python code snippet for a one-shot GUI game. Use either tkinter or Pygame. The game should have:

A single screen where the player controls a character (or shape) using arrow keys.

Randomly placed coins to collect, each incrementing the score when touched.

A simple display of the current score.
Include comments that explain your code logic, and ensure it runs out-of-the-box without additional libraries beyond the chosen GUI framework.”

4. Creative Writing

Creative writing is something AI models have been doing for a long time, but recently, writing has become more engaging and fun.

Here, I'm asking for the models to generate a sci-fi scene set on Mars with some dialogue and a cliffhanger. Dialogue and the cliffhanger are the areas I'm most looking to when it comes to judging output.

Prompt: “Write a short, suspenseful sci-fi scene (under 300 words) in which two astronauts discover a bizarre phenomenon orbiting Mars. Include a snippet of dialogue that captures the shock of what they’ve found. End on a gripping cliffhanger that leaves readers craving more.”

Claude had a good cliffhanger that builds suspense with an ominous ending. The dialogue was natural but could have been pushed further. Gemini had a weak cliffhanger that fell short but had particularly compelling dialogue that was more human. You can read both scenes in a Google Doc.

I've given it to Claude because its cliffhanger was better, and it balanced action, description and dialogue well. While Gemini's dialogue was more creative, overall Claude was better.

5. Problem Solving

Artificial Intelligence models are very good at problem-solving as they can pattern match well. Here, I gave it a gaming PC spec and said a new game was struggling to run. I had it tell me how to fix this problem.

This is something I've personally come up against and one we get asked about at Tom's Guide a lot. So, let's see how Claude and Gemini solve it.

Prompt: “I recently built a gaming PC with an NVIDIA RTX 4070, an Intel Core i7, 16GB RAM, and a 1TB SSD for storage. A new game I installed stutters every few minutes—particularly during texture loading. Provide a step-by-step troubleshooting guide addressing:

Graphics card drivers
Game settings (texture quality, resolution, etc.)
Possible temperature or cooling issues
OS updates and background processes
Any additional hardware checks or recommended upgrades

Explain why each step might help and, if relevant, include approximate costs.”

Claude's response was a bit on the dense side. Thorough but with a lot of technical detail, it also didn't go into game setting detail very much. However, that detail might be exactly what someone needs to solve the problem.

Gemini over-explained things but was comprehensive across all categories, including driver installation. It offered actionable and realistic suggestions but missed some advanced checks and didn't go into the same hardware detail as Claude.

This is a close call between the two. I think Claude provided a better-rounded guide, but Gemini gave more setting details, which is why I gave it the win. You can read both responses for yourself in a Google Doc.

6. Planning

AI models are great at planning. I decided to see how well each could manage if I prompted it to merge my kitchen and living room into an open-plan space — something my parents did a few years ago.

It needed to provide examples of designs and styles, permissions required, coordination tips and estimated costs.

Prompt: “I want to merge my kitchen and living room into one open-plan space. Provide a detailed plan covering:

Budgeting: Estimating costs for demolishing a non-load-bearing wall, new flooring, and lighting.
Design Consultation: When to involve an interior designer, examples of possible styles.
Permits & Regulations: What permissions or inspections might be needed.
Scheduling & Contractors: How to coordinate different trades and manage a realistic timeline.
Living Arrangements: Tips for coping with ongoing construction.

Then, in two or three sentences, generate a prompt for an AI image generator to create a visual mock-up of the completed open-plan kitchen-living area, incorporating key design elements from your advice.”

7. Education

I used to write a newsletter about quantum computing, I still struggle with much of the topic. So here I've asked both to explain the concepts behind the technology in simple terms with analogies to make it more relatable.

Prompt: “Explain how quantum computers differ from classical computers in everyday terms, covering:

Qubits vs. bits
Quantum superposition and what it means
Real-world use cases (current and potential)
Current hardware and scalability limitations
Why quantum computing matters for the future of technology

Use simple examples or analogies anyone could understand.”

Both responses are available in a Google Doc. My criteria include clarity and simplicity, accurate and easy-to-understand analogies, a thorough response and one that keeps me engaged in the response.

Claude offered clear analogies of superposition as a library and spinning coin to visualize bits and qubits. It also used drug discovery and traffic optimization to put it into context. However, examples were limited, focusing on professional fields, and the impact of AI was missed.

Gemini used a dimmer switch to compare bits to qubits, which is a more accessible analogy. It used the spinning coin for superposition. It also mentioned AI in real-world use cases, as well as logistics. It was a little verbose and got repetitive.

Claude won this one for me because it was more to the point and easier for non-technical readers. Gemini provided richer analogies, but Claude was more relatable to the general audience.
