Models
ChatGPT, Claude, Gemini: what's the difference, and which one for which job.
A model is the "brain" behind an AI app. ChatGPT, Claude and Gemini are apps from different companies, each running their own models. They're all good at everyday tasks, each has its own strengths, and most offer a free version plus a paid one with stronger models.
How it works
- 01Each company trains its own models on huge amounts of data, then releases them in its app.
- 02Within one app there are often several models: quick, light ones and slower, more thoughtful ones.
- 03You pick the app, and sometimes the model. The same prompt can give quite different answers.
Choosing the right babysitter
Your neighbor's teen is great for an hour of play, grandma is unbeatable for a whole weekend, and an experienced nanny is the one for a newborn. They're all good; they just suit different jobs. AI models are similar. You don't need to master all of them. Pick one main assistant, learn it well, and try another when an answer isn't landing.
Where you'll use it
Everyday help
The free version of any big AI app handles meal ideas, kids' questions and planning.
Writing and thinking
Try the same business task in two apps and keep the one whose style suits you.
Built into your phone
AI now also lives inside phones, email and search, often powered by one of these models.
Your nap-time experiment
Run a mini taste test: paste the same prompt into two different AI apps and compare.
I'm a mom with a small business and very little time. Write a short, warm Instagram caption (max 60 words) announcing that I'm launching a free AI advent calendar for moms, with one clear call to action. Then tell me in one sentence what tone you chose and why.
