Artificial Intelligence

GPT-4.5 is our most advanced model yet, scaling up unsupervised learning for better pattern recognition, deeper knowledge, and fewer hallucinations. It feels more natural, understands intent better, and excels at writing, programming, and problem-solving.

GPT-4.5 is definitely a step toward more intuitive, human-like AI—feels less like a tool and more like a thoughtful collaborator. It seems we moving into an era where AI adapts to users, not the other way around. Curious to see how different models carve out their unique strengths as subjective computing evolves.

It’s rolling out now for Pro users and API access. Priced in API at,
Input: $150/1M tokens ($37.50/1M for cached input)
Output: $150.00 / 1M tokens

Plus, Edu, and Enterprise users will get access next week.

How does it compare to other models released this week, such as Claude 3.7 and Grok-3? Is this a significant leap forward, or just the beginning of OpenAI’s push toward smarter, more context-aware models?

Comment highlights

When I click on the link to tery it in 4.0 I do not see 4.5 only the 4.0 appears.

ChatGPT is the best AI to than others, it is too fast and amazing, I am using ChapGPT on the daily basis fir the content research.

@sama It's a tough day competing with you, but we're still holding strong at the top so far! @fn7 Helix

Excited to give this a try and see how it stacks up against all the latest competition. Any idea when it will become available for Plus users?

All the best for the launch @usamaabidj & team!

hell nah bro this is too little compared to grok offering free deep research

This release seems rather underwhelming to me. I mean they've improved logical processing but the price seems way too high to me 🤔 I feel like they're trying to establish themselves as the Apple of LLMs and just thinks people will pay no matter how it changes
