An AI timeline from GPT-2 to Claude Code, looking ahead to 2028
A user frames GPT-2, ChatGPT and Opus 4.5 as markers of AI's evolution at three-year intervals, then calls the end of 2028 "hard to imagine."
TLDR
A user says GPT-2's 1.5-billion-parameter weights were released at the end of 2019, ChatGPT had over 100 million monthly active users at the end of 2022, and millions of developers used Opus 4.5 in Claude Code at the end of 2025. The post describes those developers as realizing they were in a "new world," then looks three years ahead: "End of 2028 is hard to imagine."
