In a surprise twist, paid subscribers can once again use several older AI models, including GPT-4o, GPT-4.1, and o3. GPT-4o is now a default option, while the others can be enabled via settings. These models were only deprecated last week, sparking user backlash that caught OpenAI off guard.

GPT-5 was touted as a major upgrade to ChatGPT, but not everyone thinks that’s the case: “Kill 4o isn’t innovation, it’s erasure.”

After releasing GPT-5 and removing the option for GPT-4o, OpenAI restored access to its older model after a deluge of unhappy user comments.
