https://platform.openai.com/docs/deprecations On April 14th, 2025, we notified developers that the gpt-4.5-preview model is deprecated and will be removed from the API in the coming months. Shutdown date Model / system Recommended replacement 2025-07-14 gpt-4.5-preview gpt-4.1

It’ll be sad to see it go, but I understand, it’s very expensive, I’m hesitant to continue using it myself due to the costs and my huge computations I need to run. This is not easy I’m sure, balancing power with efficiency is non-trivial.

In my benchmarks 4.1 is better than 4o which is great for most applications, but far from 4.5-preview. I guess size matters

Booooooooooooooooooooo (User expresses dismay at the news and wishes to protest the change) Can’t you just, like, double the price? If you do smart deployments and smart scaling, it should cost next to nothing in terms of overhead to have a couple of machines hold it on standby while they run 4.1 …

[image] Diet: Can’t you just, like, double the price? Rather, it will be a self-solving problem at the end of the month, when OpenAI stops giving out $75 of free tokens a day to gather our prompts and good outputs sent to the model. The only model that could follow deliberately-constructed i…

[The image is a screenshot of a webpage detailing the GPT-4.5 preview model, its capabilities, and version information, including availability and lifecycle status. (Captioned by AI)] Yep, may 26th. Dead and gone. Why are we going backward? Whyyyyy :cry: I don’t need “better” coding, I need bet…

I’m sad to see this model go. To me, this is a case where existing benchmarks don’t fully capture the true capabilities of this achievement. Perhaps it’s because grading outputs for specific use cases—like understanding intent—requires real humans rather than relying solely on an LLM or automated s…

Please don’t! GPT-4.5 is so much better in every aspect. You lied to us when you tried to sell us GPT-4o as ‘better’, but I think everyone knows, that it’s a slimmed down/watered down version of GPT-4 that you just pushed to perform better at certain benchmarks. I won’t accept that again!

I’d really like to know what’s behind this decision. 4.5 has a depth and quality that no other model comes close to providing. One day it’s praised extensively in a dedicated video, and the very next day they announce its removal from the API. I completely agree with the statements made in the video…

It is easily the best model on the internet and it’s not even close. It is by far the most able to understand complex prompts, addressing multiple issues at the same time. For coding, which other models are recommended for, it is actually still the best, because it seems able to understand far more…
