Which is best: Chat-GPT or Google Gemini? Don't ask me, I have no idea. Well, actually, I do now. Why? Because I asked my 'AI' friend Gemini (a large language model, trained by Google and based on the Gemini architecture). Are the answers I got from Gemini accurate? Who knows? For that matter, who cares? If accuracy was an issue I would check and verify, just like when I read a non-fiction article or book for any serious research I might be doing. Come on, folks, it ain't rocket science.
'Artificial intelligence' is a marketing term used by snake-oil salesmen. Very effectively, it seems: R.G. Taylor 12/16/2025

I have reproduced the Gemini-generated response text for discussion in a subsequent article which will be generated by my own wetware natural intelligence largish language model. Will link it here when I have done so. All text below is 'AI'-generated unless otherwise indicated.

Summarise the fundamental technical differences between Gemini and Chat-GPT
GEMINI RESPONSE
The fundamental technical differences between Google's Gemini and OpenAI's GPT models (like those powering ChatGPT) lie in their core design, particularly in how they handle different types of data and how much information they can process at once.
Here is a summary of the key technical distinctions:

1. Multimodality (The Core Architectural Difference)
Gemini was developed as a truly native multimodal model. This means that a single architecture can process text, images, code, and audio seamlessly, often leading to better cross-modal reasoning (e.g., understanding a chart and explaining it using text).
In contrast, earlier GPT models were primarily text-based. While current versions like GPT-4o are also multimodal, they often rely on integrating specialized components (like DALL-E) to handle non-textual data.
2. Context Window
The context window is the maximum amount of information (tokens) an AI can consider at any one time.
- Gemini boasts a significantly larger context window (up to 1 million tokens or more in its advanced models). This allows it to analyze and reason over massive documents, entire codebases, or long videos in a single prompt.
- GPT models have also expanded their context, but their current flagship models typically operate with a smaller window, although still large enough for most common tasks.
3. Ecosystem Integration and Real-time Data
- Gemini is naturally integrated into the Google ecosystem (Google Search, Gmail, Docs, etc.), allowing it to pull in current data directly and perform actions across these tools.
- ChatGPT operates as a more standalone service with broader integrations across various apps and services, but its web access relies on external tools like Microsoft Bing.
Would you like a comparison of the best use cases for each model based on these technical differences (e.g., which is better for coding, creative writing, or research)?
yes please
That's a great follow-up! The choice between Gemini and GPT-4o (or the latest GPT models) often comes down to the specific task you need to perform.
Here is a breakdown of the best use cases for each model, based on their technical strengths:
💻 Use Case Comparison: Gemini vs. GPT

🌟 Summary of Strengths
Gemini Excels at...
- Context & Scale: Processing and reasoning over massive, long-form data sets (e.g., analyzing an entire legal filing, a long scientific paper, or a full-year financial report).
- Multimodal Analysis: Tasks that involve cross-referencing information from different modalities in a single go (e.g., "Analyze the trend shown in this chart, and then look up the most recent news on that trend").
- Real-Time Data: Any task requiring up-to-the-minute facts with high reliability and traceable web citations.
GPT Excels at...
- High-Quality Code: Generating and fixing code that involves complex, multi-step logical reasoning and debugging.
- Creative Depth: Tasks where style, tone, narrative, and engaging prose are key requirements.
- Versatility & Speed: Providing fast, consistent, and highly polished results for general-purpose tasks and everyday queries.
In short
If you are an academic, legal, or financial analyst dealing with massive documents or a programmer tackling large-scale context, Gemini is often the better tool. If you are a developer, marketer, or writer looking for rapid, high-quality, and creative text/code, GPT often holds the edge.

All I have to say what a great educational article. Once again you should teach or offer a TED lecture.
Oh wow, so for deep research, Gemini is better. I have ChatGPT, Gemini, and Deepseek. But I only use ChatGPT. Maybe I should try asking all three of them the same question and see how differently they answer me
I kind of read this, but my tiny brain has not the space to accommodate it, i leave it to those who understand and have the need to understand it. It looks completely professionally done. 😍
I use ChatGPT a lot but Gemini often comes up in my Google search. I found this overview comparison interesting and useful.
