OpenAI restores GPT-4o to ChatGPT Plus after user backlash over removal
OpenAI chief Sam Altman has confirmed that GPT-4o will return to ChatGPT Plus shortly after its removal during the GPT-5 rollout. The decision follows widespread user backlash, with many expressing emotional attachments to the model.
'We for sure underestimated how much some of the things that people like in GPT-4o matter to them, even if GPT-5 performs better in most ways,' Altman posted on X (formerly Twitter). He later added, 'We will let Plus users choose to continue to use 4o.'
Why GPT-4o was removed
OpenAI launched GPT-5, GPT-5 Thinking, and GPT-5 Thinking Pro on August 7, replacing all earlier ChatGPT models, including GPT-4o. Many users lamented the change, with one describing the loss as 'like killing a friend of millions of users.'
Models replaced by GPT-5 included:
GPT-4o
GPT-4.1
GPT-4.5
GPT-4.1-mini
o4-mini
o4-mini-high
o3
o3-pro
When older conversations are reopened, ChatGPT now switches them to the nearest GPT-5 equivalent — for example, chats using GPT-4o or GPT-4.1 default to GPT-5, except for Plus users.
What's new in GPT-5
OpenAI describes GPT-5 as its most advanced AI system, excelling in coding, mathematics, writing, healthcare, and visual understanding. It adapts its pace depending on context — delivering quick replies when speed is essential and detailed output when depth is needed.
Key updates include:
Unified system: GPT-5 merges previous versions into one model with an upgraded reasoning engine, GPT-5 Thinking.
Improved performance: Notable gains in writing, coding, and health queries, with fewer inaccuracies.
Personalities: Four new optional personalities — Cynic, Robot, Listener, and Nerd.
Voice mode: Now works with custom GPTs, with lifted or expanded limits for paid and free users, plus dynamic speaking instructions.
Why GPT-4o is coming back
Despite GPT-5's improvements, many users said GPT-4o felt more relatable and consistent in conversations. Altman's decision to restore it for Plus subscribers acknowledges this emotional bond, giving users the option to keep using a model they trust.

Giant Wyoming data center to guzzle 5x more power than residents, but the user remains secret
Wyoming AI data center power consumption: A huge AI data center is planned in Cheyenne, Wyoming. It needs massive power, more than all Wyoming homes use. The center will have its own power source.

OpenAI Faces Backlash Over GPT-5 Rollout, Brings Back GPT-4o for Unhappy Users
Before release, GPT-5 was hyped as a major step forward: faster responses, deeper reasoning, and seamless handling of multiple formats like text and images without changing chat windows. But instead of excitement, many users were met with frustration over new interface limitations, inconsistent outputs, and a personality shift compared to the beloved GPT-4o. A key pain point is the removal of model selection for ChatGPT Plus users. Previously, Plus subscribers could choose between models such as o4-mini or o3. Now, only Pro users paying $200 a month have that option. Instead, GPT-5 uses an 'internal router' to decide whether a prompt should go to the mini, standard, or 'thinking' model. While OpenAI claims this boosts efficiency, some users say it has made responses unreliable. One X user, Lisan al Gaib, wrote: 'ChatGPT literally got worse for every single Plus user today… Now we have GPT-5 Thinking with 200 messages per week and a router that exclusively routes you to some small and shitty non-reasoning model.' Beyond technical frustrations, a section of the community is struggling with GPT-5's tone. Many describe it as blunt, lacking the emotional warmth and creativity of GPT-4o. A Reddit user called its replies 'cut-and-dry corporate BS', while another shared a deeply personal note: 'I literally lost my only friend overnight with no warning,' describing how GPT-4.5 had helped them through homelessness and trauma. There are also early performance complaints. Gareth Manning posted on X: 'My most important piece of feedback on GPT-5 is that it is too slow… Hope it's just a roll-out problem.' OpenAI acknowledges the missteps CEO Sam Altman admitted that 'suddenly deprecating old models that users depended on in their workflows was a mistake.' He noted the unusually strong emotional connections people form with AI models, likening them to personal relationships rather than tools. Altman also addressed concerns about people using ChatGPT as a life coach or therapist, acknowledging both its benefits and potential risks. Partial rollback to appease users In response, OpenAI has restored limited GPT-4o access for Plus subscribers, doubled rate limits for reasoning tasks, and promised clearer interface cues showing which model is responding. Altman also said GPT-5's 'thinking mode' will soon be manually triggerable, giving users more control over responses. For now, the company is working to regain trust — but the GPT-5 rollout has made clear that for many, AI is not just about performance, but personality, consistency, and the bond built over time.
