A wild ride from ChatGPT's launch to AI that talks, draws, makes movies, and works for 30 hours straight.
Just a few years ago, most people thought of AI as something from movies. Then in late 2022, a company called OpenAI released ChatGPT, and everything changed almost overnight. By January 2023, ChatGPT had reached 100 million users in just two months, making it the fastest-growing app in history at that time — way faster than TikTok or Instagram! Suddenly, anyone with the internet could ask a computer to write a poem, explain math, or help with a science project.
Since then, AI has exploded in every direction. Companies like Anthropic (which makes Claude), Google (which makes Gemini), and Meta (which makes Llama) jumped in to build their own super-smart AI helpers. AI learned to do more than just talk — it can now look at pictures, listen to your voice, watch videos, and even create movies from a sentence you type. Tools like Midjourney, DALL-E 3, and Stable Diffusion can paint amazing artwork in seconds, and Sora from OpenAI (released December 2024) can make whole video clips from words.
By 2026, AI is everywhere. Kids use it for homework help on Khanmigo from Khan Academy (which jumped from 40,000 to 700,000 student users in just one school year!). Doctors use AI to spot diseases. Coders use it to write programs. The newest AIs are called "agents" — which means they don't just chat, they can actually do tasks for you, like planning a trip or building a website all by themselves.
It took Instagram 2.5 years and TikTok 9 months to reach 100 million users. ChatGPT did it in just 2 months.
Claude's models are named after poems! Haiku is short and fast, Sonnet is medium, and Opus is the biggest and smartest — just like poems of different lengths.
AI can work for 30 hours straight! Claude Sonnet 4.5 can keep working on a hard task by itself for over 30 hours without stopping — longer than you're awake in a day!
Months it took each app to reach 100 million users.
