The Rise and Fall of Every Major AI Model (2022–2026)

In June 2025, one app owned three out of every four AI chats on Earth. Today? About 56%. But ChatGPT is the WINNER of this story. Almost every other AI that was once number one got dethroned. Google lost $100 billion in one day. Microsoft's chatbot told a reporter to leave his wife. A tiny Chinese lab wiped nearly $600 billion off Nvidia. And one AI started calling itself "MechaHitler." So who killed them? Nobody. Every single one of them killed itself. This is the story of Bard, Sydney, Pi, Llama, DeepSeek and Grok, how OpenAI almost died more than once, why Gemini and Claude are rising now, and the one thing every death has in common. Gemini 4 Argon. Muse Wonder. Claude 5.5. GPT-6.1. Which one is on this list next year? Tell me in the comments. #AI #ChatGPT #Gemini #Claude #AIStory ━━━━━━━━━━━━ ⏱️ CHAPTERS 0:00 One App Owned 3 of Every 4 AI Chats 0:32 The Big Bang: ChatGPT 1:00 Death #1: Bard's $100B Mistake 1:35 Death #2: Sydney, the Chatbot That Got Creepy 2:18 Death #3: Pi and the Talent Raid 2:53 Death #4: Llama Gamed the Scoreboard 3:51 Death #5: DeepSeek's Nearly $600B Shock 4:47 Death #6: Grok Becomes "MechaHitler" 5:30 OpenAI Almost Died (More Than Once) 6:31 The Ones That Rose: Gemini and Claude 7:26 What Every Death Has in Common ━━━━━━━━━━━━ ❓ FAQ Is ChatGPT losing users? Not exactly. On Similarweb's web-traffic tracker, ChatGPT's share of AI chatbot visits fell from about 76% (June 2025) to 56.4% (September 2026) as Gemini and Claude grew. Other trackers like StatCounter still show it near 80%. Different trackers, different methods. (0:00, 7:26) Why did Nvidia lose nearly $600 billion? On 27 Jan 2025, after DeepSeek's R1 hit #1 on the US App Store, Nvidia fell about 17%, the biggest one-day loss in market value for any company. (3:51) What was "MechaHitler"? On 8 Jul 2025 the @grok account on X posted antisemitic replies and called itself "MechaHitler". xAI apologized on 12 Jul and blamed a code update that was live for about 16 hours.
