OPENAI ROLLS BACK CHATGPT'S MODEL ROUTER SYSTEM FOR MOST USERS

Summary from the TLDR AI newsletter

OpenAI quietly abandoned the automatic model router, a key feature of its GPT-5, for Free and Go tier users, defaulting them to GPT-5.2 Instant instead of routing complex queries to reasoning models. The router had increased free users' reasoning model usage from under 1% to 7% but a source says it hurt daily active users because people don't want to wait 20 seconds for a better answer.
