My neighbour watered my plants for two weeks while I was away. Write a short, warm thank-you note I can leave with a small gift. Keep it under 80 words.

In plain words

Grok 4.5 is a chat assistant from xAI. It can search the web, read photos and documents, and it thinks before it answers on harder questions.

What people usually notice is its tone. It tends to be direct and a little informal, with less of the polite padding you get from some assistants. Some people love that, others prefer a softer style. Try it and see which you like.

How to get the most out of it

  1. Ask it to check the web when the question is about something recent, and ask for links.
  2. Set the tone if it matters. “Write this formally, for a bank” or “keep it gentle, this is for my aunt”.
  3. Ask what’s confirmed and what isn’t on news stories. Early reports often change.
  4. Send a photo instead of describing a problem. It’s quicker and clearer.
  5. Ask for a short answer first, then ask for more detail if you need it.

If you share what it finds with friends or family, check the original source first. That’s good advice with any assistant, and more so with fast-moving news.

When to pick another model

If you mostly work with PDFs and photos, Gemini 3.1 Pro is worth a try. Not sure? Read which model should I use.
