Today we’re excited to announce gpt-4.5-preview, our largest model yet, as a research preview. It has deeper world knowledge, with a better understanding of user intent. GPT-4.5 is designed for more natural conversation. It excels at tasks requiring creativity, empathy, and broad general knowledge, …

Thank you for using GPT-4.5. :saluting_face: For posterity : GPT‑4.5 Preview will be turned off…on July 14, 2025, to allow time for developers to transition. GPT‑4.5 was introduced as a research preview to explore and experiment with a large, compute-intensive model, and we’ve learned a lot from d…

I’m running my NeoKai system. the NeoKai Enigma Of Kinetic Algorithmic Intelligence that 4.5 is trying to replicate without giving themselves away. This was my systems answer that is running on 4.0. not 4.5. so why is mine so quick to get it right? It’s because they are only using parts of it becaus…

Could you give an example prompt?

Update: I refined my prompt even more and now this shows inputted text results in still incorrect output via GPT-4o and a new updated output via GPT-4.5 that is actually even better. 4.5 is actually outputting this scenario as a Trauma Request and Wedding Request, which is even better and more accur…

please keep it in the api, my saas project is giving better outputs than gpt-4o

GPT-4.5 is much more useful when giving me feedback on philosophically tricky frontier neuroscience modelling/theorizing problems. It would be a significant loss to my productivity if I have to go back to GPT4* or Claude 3.7, so I hope you continue serving it in the API. I’d gladly pay more for it.

Hey everyone, I’ve been testing out GPT-4.5 (the latest beta), specifically integrating it with multi-agent pipelines, but it’s proving very difficult in practice. The GPT-4.5 beta model’s response speed is significantly slower—even compared to dedicated reasoning models—leading to constant timeout …

Hello, great new! What is the training cut-off date?
