OpenAI Brings GPT-4o AI Model Back to ChatGPT after User Complaints, Revises GPT-5 Thinking Rate Limits

OpenAI is finally bringing back the GPT-4o artificial intelligence (AI) model to ChatGPT, after retiring it last week. The San Francisco-based AI firm removed the older model after the launch of the GPT-5 model, highlighting that the new frontier model can handle both reasoning and conversational tasks. However, many users took to social media platforms to highlight that they preferred 4o’s responses more than GPT-5’s.
