OpenAI plans to phase out GPT-4.5, its largest-ever AI model, from its API
On Monday, OpenAI announced that it will soon discontinue the availability of GPT-4.5 through its API. This massive AI model, which was only released at the end of February, will no longer be accessible to developers after July 14. They'll need to switch to another model from OpenAI's lineup, with the newly launched GPT-4.1 being recommended as the go-to alternative.
According to an OpenAI spokesperson who spoke to TechCrunch via email, "GPT-4.1 offers similar or improved performance compared to GPT-4.5 in key areas, but at a much lower cost." The company also stated its intention to phase out GPT-4.5 in order to focus on developing future models.
It's important to note that while GPT-4.5 will be removed from the API, it will still be accessible in ChatGPT for paying customers in a research preview mode. The model, code-named Orion, was trained with unprecedented amounts of computing power and data. It surpasses its predecessor, GPT-4o, particularly in writing and persuasiveness. However, despite its impressive scale, GPT-4.5 doesn't quite reach the "frontier level" on various industry benchmarks.
OpenAI has also acknowledged that running GPT-4.5 is incredibly costly. Back in February, they hinted at potential long-term limitations on its availability through the API due to these costs. The pricing for GPT-4.5 reflects this, coming in at $75 per million input tokens (about 750,000 words) and $150 per million output tokens, making it one of the priciest options in OpenAI's suite of models.

Wow, OpenAI is already sunsetting GPT-4.5? That’s wild—feels like it just dropped! Curious to see what developers pivot to next. 😎

OpenAIがGPT-4.5をAPIから削除するって聞いてびっくり！😱 自分の技術からこんなに早く離れるなんて信じられない。ようやく慣れてきたのに、また新しいモデルに切り替えないといけないんだ。新しいのが期待できるといいけどね！🤞

Me siento un poco decepcionado de que OpenAI vaya a eliminar el GPT-4.5 tan pronto. Apenas empecé a usarlo y estaba bastante bien. Ahora tengo que cambiar a otro modelo y aprender todo de nuevo. ¿Por qué no pueden mantenerlo un poco más? 😕

Fiquei meio chateado que a OpenAI vai descontinuar o GPT-4.5 tão cedo. Acabei de começar a usar e estava bem bom! Agora tenho que mudar para outro modelo e aprender tudo de novo. Por que não podem mantê-lo por mais tempo? 😕

OpenAI इतनी जल्दी GPT-4.5 को बंद करने जा रहा है, इससे मुझे थोड़ा निराशा हुई। मैंने इसका उपयोग शुरू ही किया था और यह काफी अच्छा था! अब मुझे दूसरे मॉडल पर स्विच करना होगा और फिर से सब कुछ सीखना होगा। क्या वे इसे थोड़ी देर और नहीं रख सकते? 😕

OpenAIがGPT-4.5をこんなに早く廃止するなんて残念です。使い始めたばかりだったのに、結構良かったんですよね！今度は別のモデルに切り替えないといけないし、また一から学ばないといけない。もう少し長く使えないかな？😕
