ChatGPT won’t remove old models without warning after GPT-5 backlash
After users mourned the sudden switch from GPT-4o to GPT-5, ChatGPT lead Nick Turley admitted removing 4o without warning was “a miss.” He noted people form strong attachments to a model’s “personality” and pledged future retirements will come with advance notice. OpenAI is also working to bring GPT-4o’s “warmth” into GPT-5, CEO Sam Altman added.
