From an earlier video
This is material from an earlier video — the interfaces and features of AI services may have changed since. The idea and the approach still hold.
🧠 What if you had an assistant that instantly understood text, photos, PDFs and even video? That's Gemini.
What kind of model is it?
Gemini is Google’s new line of multimodal models. Unlike many other AIs, Gemini was trained simultaneously on text, images, video and audio.
That makes it especially flexible at understanding and analysing information.
🧠 Multimodality — what does it mean?
You can upload to the chat:
- a PDF (a lecture, report, book),
- a screenshot or a photo of a whiteboard,
- a link to a YouTube video,
- or just ask a question out loud —
And Gemini will combine it all, understand it, and give you a meaningful answer.
🔍 How is Gemini different from ChatGPT?
| Parameter | Gemini 2.5 Pro | ChatGPT GPT-4 |
|---|---|---|
| Multimodality | ✅ yes | ⚠️ limited |
| Context (tokens) | up to 1,000,000 | up to 128,000 |
| Speed | Fast (Flash model) | Depends on plan |
| Google integration | Full (Drive, Gmail) | ❌ none |
| Working with video and PDF | ✅ works great | ⚠️ partial |
| Conversational language | 🤔 average | ✅ good |
Bottom line: Gemini suits you better if you work with documents, video, presentations and Google’s cloud.
