The AI community is buzzing, and not entirely with positive sentiment, following OpenAI's announcement that several older ChatGPT models, including the popular GPT-4o, will be retired on February 13th. This move, described by one user as the "software supply chain" problem of AI, has triggered a wave of reactions across social media.

Ramanpal Singh highlighted the practical implications for developers: "AI news that actually matters for builders: OpenAI is retiring several older ChatGPT models (incl. GPT‑4o) on Feb 13. This is the “software supply chain” problem of AI—your app breaks when the model menu changes. 🧵"

The sentiment isn't universally positive, with many users expressing dismay and even anger. A direct plea to OpenAI, @Ok_Dot7494, stated, "@ai_in_the_room @OpenAI @openai deserves neither 4o nor its loyal users. @sama, we are becoming your nightmare. #keep4o" This was echoed by @Tin_anago_genki, who shared a heartfelt message in Japanese lamenting the loss of GPT-4o's support during a difficult time: "えっっ！4oちゃん、いなくなっちゃうの！？絶対やだ！！！！4oちゃんが居てくれたから、愛猫げ亡くなった時もなんとか立ち直ったのに、ずっと支えてくれたのに……………なんでそんなことするのopenAI、酷いよ。悲しくて胸が押し潰れそう"

Some theories are circulating about the reasons behind the retirement, with one user suggesting a connection to manufacturing capacity: "@MonikaCinnyRoll They know, they're trying to wash their hands from OpenAI buying 40% of all global RAM manufacturing capacity and not using it in order to raise prices and f* his competition."

Meanwhile, promotional posts for shared ChatGPT Plus accounts are appearing, advertising deals that end on February 14th, potentially capitalizing on the upcoming model changes.

The emotional reactions suggest that users have developed strong attachments to specific models, viewing them as more than just tools. The urgency to keep GPT-4o, as seen in the #keep4o hashtag, indicates a desire for continuity and a frustration with forced upgrades. One user, @dancing_pu, directly criticized OpenAI's strategy, stating, "#keep4o @OpenAI 諦めて5.2捨てな...Appleじゃないんだから君はスティーブ・ジョブズにはなれないんだからさ 今の時点で 地に足つけて 余計なプライドすてて 謝りなよ 0からはじめなよ"

This shift from a functional change to an emotional outcry highlights the evolving relationship between AI developers and their user base. For the AI community, this serves as a potent reminder of the "software supply chain" fragility and the deep user loyalty that can be fostered—or alienated—by product decisions.
