OPENAI MIGHT BE TESTING GPT-5.1-MINI UPGRADE FOR CHATGPT

Summary from the TLDR AI newsletter

ChatGPT's model selector temporarily showed 'GPT-5 Mini Scout' for some business account users on Friday, sparking immediate speculation about its purpose. An update to OpenAI's official JavaScript agent library surfaced shortly after with a new reference to 'GPT-5.1 Mini' in a test file, suggesting that 'GPT-5.1 Mini' was the intended production name for 'Mini Scout'. References to the new model have since been removed.
