# AI Quick Tips 214: What is ChatGPT?

 August 26, 2025

Since I think that there are more beginners out there than anything, this one is for you.

I’ve been thinking about a concise and accurate answer to this question for a while and it is harder than it seems.  All of the accurate answers would put you to sleep *(aka - not concise)* and all of the concise answers only cover a small fraction of what can be done.  

I think that a layered approach would be the best of both worlds.  Here’s what I mean -

### What is ChatGPT? (Didn’t we ask this already…)

**ChatGPT is a chatbot that gives you access to AI models**

### Great but what’s a chatbot and what are models?

A chatbot is a program that simulates human conversation.

According to IBM, an AI model is: 

*A program that has been trained on a set of data to recognize certain patterns or make certain decisions without further human intervention*

### What kind of [models](https://thoughtsbrewing.com/blog/tag/models) can ChatGPT access?

- **Large Language Models (LLMs)** - simply put, they are text generation machines.  They take input, process it, and generate output
- **Vision Language Models (VLMs)** - models that can understand and process text and visual data (i.e., images, video, etc.)
- **Multimodal models** - models that can process information from text, images, video, audio, etc. (multiple modalities)

### Put it all together

ChatGPT and other similar AI tools like Gemini, Perplexity, Claude and Copilot (among others) provide easy-to-use interfaces that allow users to access AI models.  Once people have access to the models they can do stuff.

What kind of stuff?  (Look at the rest of the [blog](https://thoughtsbrewing.com/blog/tag/ai)…)

Now go experiment!
