RETIRING GPT-4O AND OLDER MODELS

Summary from the TLDR AI newsletter

GPT-4o, GPT-4.1, GPT-4.1 mini, and certain other older models will be retired on February 13 to streamline capabilities and transition users toward newer generations like GPT-5 and beyond. GPT-4o in ChatGPT had been restored after earlier deprecation due to user feedback, but the final retirement reflects broader adoption of more capable models. While the change affects the consumer ChatGPT experience, there are currently no simultaneous API changes, and developers relying on older models will be guided to migrate to newer alternatives as part of normal deprecation practices.
