ChatGPT — orientation

In late 2022, a research preview called ChatGPT reached a hundred million users faster than any consumer product before it — and made “talking to an AI” an ordinary thing to do. Whatever assistant you end up preferring, you’ll meet ChatGPT everywhere, so let’s take the tour.

The fact sheet (community-verified)

What it’s typically good at

ChatGPT is a strong all-rounder across the whole strong zone you mapped in E1·L8: drafting and rewriting, explaining, brainstorming, summarising, and working with material you paste in. Its ecosystem is broad — voice conversation, image understanding and generation, file reading, and web search, depending on tier. For many people it’s the default because it’s capable at most things, not because it’s best at everything.

What to keep in mind

Everything from E1 applies at full strength. It hallucinates exactly as L7 described — fluently. Specifics, citations, and recent facts get the three-question habit, every time.
Conversations are windows, not memories. A new chat starts fresh; long chats can slide early details out of view (E1·L6). Assistant “memory” features save notes between chats — useful, and worth reviewing what’s been saved.
Tiers move. Which models and tools the free tier includes changes often. The card above links to the official docs — trust those over any screenshot you find online, including ours if the card goes stale.

Try it now (5 minutes)

Open ChatGPT (free tier is fine) and run this structured request: “Rewrite the following note as a short, friendly email to a colleague. Keep it under 120 words and end with a clear question.” — then paste any rough note of yours. Evaluate the result like an E1 graduate: Is it faithful to your meaning? Anything invented? What would you tweak in a follow-up message? Make that tweak — iteration is tomorrow’s lesson topic.

Check your understanding

1. You ask ChatGPT about your previous conversation from last week. What should you expect? Full recall — everything is always remembered A fresh start unless a memory feature has saved and re-inserted notes An error message

2. ChatGPT gives you a statistic with a confident source. Per this course, you should: Use it — sources are auto-verified Verify the source exists and says that, before relying on it Ask the model if it is sure, and accept its answer

Recap

A capable all-rounder with a broad ecosystem; windows not memories; every E1 habit applies unchanged. Next: Claude — and your first real taste of how assistants differ in character and strengths.
