ChatGPT Switches Default Model to GPT-4.1 Mini for All Users, Subscribers Get GPT-4.1

GPT-4.1 (and -mini and -nano) are now available in the API! these models are great at coding, instruction following, and long context (1 million tokens). benchmarks are strong, but we focused on real-world utility, and developers seem very happy. GPT-4.1 family is API-only.

This is also, I suspect, why OpenAI’s ChatGPT is causing the freakout that is inside of Silicon Valley. Yes, the AI is exciting, but the fact the platform has over 100 million monthly users, over a billion visitors a month, and an estimated two million that are paying to use it, seems like the bigger deal.
