GPT-4.5 - The largest and best model for chat yet in GPT family

by

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?

@usamaabidj don't know if it was the original plan, but it's really cool to see this one is not a step forward in the main benchmarks but something different. We need models that are better at driving conversations and adapting their tone, and this looks like the best ever at that!

@usamaabidj Congratulations :)

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

Amazing! How does GPT-4.5 handle bias in its unsupervised learning?
