Everyone is talking about Gemini 3 Pro.
And after several days of tests, demos, and comparisons, the verdict is simple: it's not just another update.
Maybe it's time for Google to switch back to OpenAI.
Feedback from a historical ChatGPT user... who is beginning to have doubts.
The perfs: Gemini 3 Pro breaks the hierarchy
Always first on the benchmarks
The numbers all fall on the same side: Gemini 3 Pro outperforms GPT-4 on the majority of technical tests.
Concrete gains:
- higher execution speed
- more reliable answers
- better understanding of the context
- finer technical precision
But it is above all in real use that the difference is visible.
Deep Think: the parallel reasoning that changes everything
Gemini's real innovation is reasoning nonlinear.
- GPT-4 : think step by step.
- Gemini 3 Pro : explores several paths in parallel and synthesizes.
The result: answers that are more complete, more nuanced, and often faster.
In complex tasks, the difference is clear.
Ultra-multimodality: Gemini understands (and produces) everything
Gemini 3 Pro is multimodal In both directions.
Input: text, images, long videos, audio, code
Output: structured text, images, videos, slides, slides, interactive interfaces, functional code
And above all: He chooses the right answer format by himself.
No need to specify “Make me a board/a slide/a video”.
Dynamic interfaces: the AI that builds mini-apps
It is one of the most impressive functions:
Gemini doesn't just return text. It generates living interfaces.
Examples: designed slides, visual layouts, interactive dashboards, mini-apps, manipulable visualizations...
ChatGPT does not offer anything equivalent today.
A concrete case: a video game created with Gemini
The expert Ludovic Salenne showed this in a spectacular way in his video test here.
- concept via a prompt
- Automatically generated slides
- video analysis
- Code production
- playable game
All in one flow.
This is the promise of multimodality finally fulfilled.
A more professional tone: Gemini does not flatter
Notable difference:
Gemini is not looking to round corners.
- GPT chat : encouraging, sometimes too accommodating.
- Gemini 3 Pro : factual, direct, effective.
On a pro workflow, this is nice: fewer frills, more info.
Google integration: the secret weapon
This is THE point that comes up among all experts:
Gemini isn't just an AI... it's an AI natively plugged into all of Google.
Deep integrations:
Gmail, Drive, Sheets, Slides, Slides, Calendar, Search, Android
No plugin, no hack, no external gateway.
And Gemini works directly in your apps to:
- Find and summarize emails
- Generate a table in Sheets
- prepare a complete presentation
- schedule a meeting in Calendar
It's a huge time-saver if you're already living in the Google ecosystem.
My favorite use case: video analysis
It's simple: at the moment, ChatGPT doesn't know how to do it.
And for a creative studio like HEYIA, it has become indispensable.
What we do with:
- identify the best moments of a testimonial
- summarize long interviews
- extract strong quotes
- analyze our creations
- propose reasoned improvements
This capacity opens up a huge playing field for:
- content creators
- marketers
- trainers
- brand teams
UX: Gemini offers a pleasant interface
Google has set the bar high:
- more modern interface
- better formatted answers
- smooth integration of images/videos/slides
- more intuitive navigation
On a daily basis, it changes everything.
ChatGPT vs Gemini: my user dilemma
I have been a heavy user of ChatGPT from the start.
But for the first time, I'm wondering if I should migrate everything.
What's holding me back at ChatGPT:
- my habits
- The history
- The plugins
- The massive community
What makes me want Gemini:
- video analysis
- real multimodality
- Google integration
- dynamic interfaces
- raw perfs
- More direct tone
For now, I am working in hybrid :
- ChatGPT → writing, brainstorming, long conversations
- Gemini → video, Slides/Sheets, interfaces, advanced analysis
But the scale is tilting.
Is it the end of ChatGPT? No But...
ChatGPT has real advantages: ecosystem, plugins, stability, habits.
But Gemini takes advantage of: performance, multimodality, integration, video, UX.
The match is on and that's great news.
Conclusion: the best choice depends on your use
Choose Gemini 3 Pro if:
- You work on Google Workspace
- video analysis is key
- you want to generate dynamic interfaces
- you prefer raw performances
Stay on ChatGPT if:
- your workflows are already concrete
- you use specific plugins
- You are not in the Google ecosystem
- You are waiting for stabilization
The truth: testing both is still the best strategy.
The battle is on, and our productivity is winning.
