OpenAI’s GPT-5 Rollout Causes Outcry: Users Lose Access to Older Models, Question New Model’s Performance

In a significant development this week, OpenAI unveiled GPT-5, its latest and most advanced model, with CEO Sam Altman claiming it offers PhD-level expertise across various fields. However, the rollout has been met with concern from some users who have lost access to previous models they had grown accustomed to, including GPT-4o, o3, o4-mini, GPT-4.1, and GPT-4.5.

This change has disrupted workflows for many and even impacted mental health in one reported case. Users have taken to social media to express their concerns and frustration. However, those who miss the older models can still access them, albeit at a cost – a $20 monthly subscription for the Plus plan.

OpenAI has not yet confirmed if access to legacy models will be extended in response to high demand. In a recent post on X, the CEO stated, “We will monitor usage as we consider how long to continue offering legacy models.” Access to older models is not available for free users. Initially, access was limited to $200/month Pro users, but this seems to have been revised following the backlash.

Some users on social media have called for GPT-4o to be made accessible to all users. Loss of access to older GPTs isn’t the only issue that has arisen since the tool was launched. Others have accused it of being “sterile,” saying it lacks the same feel as its predecessors.

Nostalgia for older chatbots seems to be growing, as evidenced by a recent funeral held for Anthropic’s phased-out Claude 3 Sonnet. According to Wired, around 200 AI enthusiasts attended the event, although many were associated with the company.

While GPT-5 is the latest advancement in AI technology, its rollout has not been without controversy and user dissatisfaction. Users are hoping for improvements and increased functionality as the tool continues to develop.
