===Removal of ChatGPT-4o and other legacy models (August 2025; February 2026)===

With the launch of GPT-5 in August 2025, OpenAI removed legacy models from non-API users, such as GPT-4o. This decision caused an outrage, with users complaining about the removal of the models along with the complaints about GPT-5. OpenAI's response was to end paywalling these older models, making them available only for Plus users.

In 2026, OpenAI announced they will be removing definitely GPT-4o and other models, such as GPT-5 and GPT-4.1. On February 13, 2026, 4o and other legacy models were removed for non-API users, causing again controversies in social media.
