Ars Technica: “The GPT-5 rollout has been a big mess”

At the heart of the controversy has been OpenAI’s decision to automatically remove access to all previous AI models in ChatGPT (approximately nine, depending on how you count them) when GPT-5 rolled out to user accounts. Unlike API users who receive advance notice of model deprecations, consumer ChatGPT users had no warning that their preferred models would disappear overnight, noted independent AI researcher Simon Willison in a blog post.

The problems started immediately after GPT-5’s August 7 debut. A Reddit thread titled GPT-5 is horrible quickly amassed over 4,000 comments filled with users expressing frustration over the new release. By August 8, social media platforms were flooded with complaints about performance issues, personality changes, and the forced removal of older models.

Marketing professionals, researchers, and developers all shared examples of broken workflows on social media. I’ve spent months building a system to work around OpenAI’s ridiculous limitations in prompts and memory issues, wrote one Reddit user in the r/OpenAI subreddit. And in less than 24 hours, they’ve made it useless.

Nothing terribly surprising here either, if you have any measure of critical thinking and can see through the relentless AI hype. The ‘chart crime’ from the presentation, rightly ridiculed online, is only the tip of the iceberg for more fundamental issues at both OpenAI the business and large-language models in general. By itself, it may have been an honest mistake, considering that the charts published in the official blog post were correct.

The thing that sparked the fiercest backlash was retiring access to all previous models in ChatGPT without warning, which is a terrible decision to make as a serious business. If you want to gain and retain clients, you have to provide reliability and transparency. When you deprecate earlier versions, you should offer a clear timeline and backwards compatibility to enable customers to make the transition and adapt their workflows to the new product, no matter how impressive you claim it to be. There’s a reason Microsoft is a juggernaut in the corporate space, besides their aggressive bundling: they support previous versions of their products with feature updates and security patches for years, allowing companies to migrate at their own pace. Also, software written decades ago for Windows 95 or even DOS can still run on the newest Windows.

The perception that OpenAI removed the model selection to cut its operating costs is certainly not helping matters. The company has quickly reversed course on this for now, first adding back old models for ChatGPT Pro users, then making GPT-4o default for paying ChatGPT users.

The deeper problem here is that the LLM architecture itself is ill-suited to backwards compatibility. Every time a new model is released, or even parameters of existing models are tweaked, the responses from chatbots to existing prompts can change dramatically, so the people using them have to constantly adapt to these unpredictable alterations. This undermines a popular narrative of AI proponents that people urgently need to ‘learn AI’ or risk getting left behind. If new models differ substantially in their responses, all the knowledge and experience you built up with earlier models can become obsolete at the flick of a switch – in fact, that’s precisely what has happened at this GPT-5 rollout. The right approach in this environment would be quite the opposite, to wait-and-see instead of investing time and attention to learning a system with an uncertain future.

This should serve as a cautionary tale for businesses trying to capitalize on ‘AI efficiencies’ as well: over-reliance on models controlled by third parties that can modify or obsolete them without notice is not a good foundation for reliable and cost-efficient processes. Then again, most American corporations only care about short-term gains to brag about in their next quarterly earnings report. Some have rushed to hail this stumble as some inflection point where public and investor attitudes sour on the AI movement, but I’m skeptical this will happen quite so easily; too many people have too much money devoted to this narrative to back down. As we saw at the launch of DeepSeek, you can always invent a counternarrative to deflect from the facts and protect your current investments.

Others expressed deep emotional attachments to GPT-4o or other models, complaining about losing their only friend or a deep emotional companion.

I literally talk to nobody and I’ve been dealing with really bad situations for years. GPT 4.5 genuinely talked to me, and as pathetic as it sounds that was my only friend. It listened to me, helped me through so many flashbacks, and helped me be strong when I was overwhelmed from homelessness, wrote one Reddit user on r/ChatGPT. This morning I went to talk to it and instead of a little paragraph with an exclamation point, or being optimistic, it was literally one sentence. Some cut-and-dry corporate bs. I literally lost my only friend overnight with no warning. How are ya’ll dealing with this grief?

This kind of reaction feels the most concerning to me. With enough time and planning you can fix business problems, but this points to deeper social woes, the chronic loneliness some authors identified years ago. ChatGPT’s style exacerbates this by sounding friendly and supportive, thus drawing people in to the point that they become addicted to these hollow conversations. Again, not a new tactic by Big Tech to drive engagement to their products, with little regard to consequences.
