ChatGPT users dismayed as OpenAI pulls popular models GPT-4o, o3 and more — enterprise API remains (for now)

Summary
According to comments made by OpenAI to VentureBeat, all existing models on the ChatGPT platform will be replaced by the GPT-5 flagship model.
Users will no longer be able to choose between GPT-4o, o3, o4-mini or o4-mini-high and will have to use GPT-5 for all functions once it becomes available.
Reaction to the news has been mixed; while some users claim to have developed a connection to their preferred model, others welcome the move as a way of forcing users to adopt the most capable models.
OpenAI has also sought to reassure enterprise users that API access to existing models will remain in place and developers will be warned in advance if models are to be deprecated.
Existing enterprise users will be able to access all legacy models for 60 days.
