As GPT-5 model faces backlash, OpenAI brings back legacy models for customers

Just a day after replacing it with its newly launched GPT-5, OpenAI had to reinstate the GPT-4o model for paid ChatGPT subscribers. The move comes in the wake of widespread criticism from users who were unhappy with losing access to the older model, which many had integrated into their daily workflows.

The rollout of GPT-5 was met with mixed reactions despite promises of significant improvements over its predecessor.

For instance, in an AMA session on Reddit, several users told CEO Sam Altman that GPT-5 felt “dumber” and lacked the warmer personality of GPT-4o. Some also expressed frustration at the abrupt removal of legacy models without prior notice.

Acknowledging these issues, Altman confirmed that the router had been underperforming and stating that GPT-5 would “seem smarter starting today”. He also pledged to make it clearer which model is responding to a given query.

Initially, the update also removed ChatGPT’s model picker, which previously allowed users to manually select between different versions like GPT-4o, GPT-4.1 or the o4 mini model. As of now, ChatGPT Pro, Team and Enterprise customers can once again choose GPT-4o through the “show legacy models” option in settings, while free-tier users remain limited to GPT-5.

Altman further asserted that OpenAI will monitor usage before deciding how long to support older models, and indicated that GPT-4.1 could return if there is enough demand from Plus subscribers. He added that the company will “continue to work to get things stable” and keep listening to user feedback.
