HomeOpenAI to Phase Out GPT-4 from ChatGPT Soon
OpenAI is set to phase out its groundbreaking AI model, GPT-4, from ChatGPT, as announced in a recent changelog update on Thursday. Starting April 30, GPT-4 will be completely replaced by the newer GPT-4o, which has been serving as the default model in ChatGPT. However, fans of GPT-4 can still access it through OpenAI's API.
According to OpenAI, GPT-4o has shown superior performance over GPT-4 in various domains such as writing, coding, and STEM. "Recent upgrades have further improved GPT-4o's instruction following, problem solving, and conversational flow, making it a natural successor to GPT-4," the changelog states. It's clear that OpenAI believes GPT-4o is the next big step forward.
Launched in March 2023, GPT-4 was initially introduced for use in ChatGPT and Microsoft's Copilot chatbot on the web. What made several versions of GPT-4 stand out was their multimodal capabilities, enabling them to process both images and text—a first for a widely deployed model from OpenAI.
The development of GPT-4 was no small feat. OpenAI CEO Sam Altman revealed that the model, which is reportedly enormous, cost over $100 million to train. It was later followed by GPT-4 Turbo in November 2023, which promised faster processing and lower costs.
GPT-4 has not been without controversy. It's at the center of ongoing copyright disputes with publishers, including The New York Times, who claim that OpenAI used their data to train the model without permission. OpenAI, on the other hand, argues that its use falls under fair use protections.
With GPT-4's retirement on the horizon, OpenAI appears to be gearing up for a new wave of models in ChatGPT. According to reverse engineer Tibor Blaho, the company is preparing a suite of models named GPT-4.1, which includes versions like GPT-4.1-mini, GPT-4.1-nano, and GPT-4.1. Additionally, OpenAI is working on the o3 "reasoning" model announced in December and a new model called o4-mini. It's an exciting time for AI enthusiasts as we anticipate what these new models will bring to the table.

GPT-4がもうすぐ使えなくなるなんて…😢 新しいモデルは確かに速いけど、GPT-4の安定した応答が好きだったんだよね。特に長文生成の質は個人的に最高だと思ってた。アップデートは仕方ないけど、ちょっと寂しいな。4月30日までに使い倒さなきゃ！

GPT-4がもうすぐ使えなくなるなんて…😢 新しいモデルは確かに速いけど、GPT-4の安定した応答が好きだったんだよね。特に長文生成の質は個人的に一番信用してた。AIの進化は嬉しいけど、使い慣れたツールが消えていくのは少し寂しいな。次はどんなモデルに取って代わられるんだろう？

GPT-4 part déjà ? 😮 C’est incroyable à quelle vitesse ces modèles évoluent. D’un côté, c’est passionnant de voir les progrès, mais d’un autre ça m’inquiète un peu pour la stabilité des outils qu’on utilise quotidiennement. Est-ce que GPT-4o sera vraiment plus fiable ou c’est juste une mise à jour marketing ? En tout cas, heureusement qu’on peut encore y accéder pour un temps.

GPT-4がもうすぐ使えなくなるなんて…新しい技術ってすぐ陳腐化するんだね。個人的にはGPT-4の方が応答が落ち着いてて好きだったんだけど、時代の流れには逆らえないのかな？🤔

GPT-4 要下架了？我還蠻喜歡它的穩定表現的說...新版本 GPT-4o 雖然快但覺得有時候回答太活潑了？希望未來可以保留讓使用者自選模型的彈性 🤔

Wow, GPT-4 getting phased out already? Feels like it just dropped! GPT-4o sounds promising, but I’m curious if it’ll really outshine its predecessor or just be a flashy upgrade. Anyone tried it yet? 🤔
