GPT-4.5: Analysis of OpenAI's Latest AI Models

GPT-4.5is the latest big language model released by OpenAI on February 27, 2025, still at the original price of just$20You'll get access to the GPT-4.5 Research Preview. This is the most powerful and intelligent AI language model currently available in OpenAI. It's available in natural conversation,Depth of knowledge,Creative Ideasrespond in singingcompose and other aspects are significantly improved over the previous version, and the key thing is that this version supports theinference-free modelIt's also a direct way to quickly and accurately answer questions asked by users. In this article, we will analyze the new technology upgrade of GPT-4.5 and its impact on AI development in detail.

🌟 Major upgrades to GPT-4.5

1. Extended unsupervised learning

GPT-4.5 takes a significant step forward in unsupervised learning. By scaling pre-training and post-training, the model's ability to recognize patterns, make connections, and generate creative insights without the need for inference has been improved. This makes GPT-4.5 perform even better when dealing with complex tasks.

2. More natural interaction experience

Early tests show a more natural interaction experience with GPT-4.5 compared to GPT-4o. It has a broader knowledge base, improved understanding of user intent, and higher "emotional quotient (EQ)" to excel in tasks such as writing, programming, and solving real-world problems.

Most importantly, GPT-4.5 was reduced in thefigment of one's imagination(which refers to the phenomenon of AI models generating content that is factually inaccurate, unsupported, or logically implausible) performs very well in terms of37% only, which is much lower than other versions, enhances the message of thedependabilityrespond in singingaccuracy, which is a very big step forward because the illusion rate is a very difficult point to break in AI technology.

3. Multilingual support

GPT-4.5 performs well in multi-language support. In the MMMLU test set, GPT-4.5 tested 15 languages including Arabic, Bengali, Chinese, English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese, Spanish, Kiswahili, and Yoruba, and on all languages itBetter than GPT-4oThe

4. Security and reliability

GPT-4.5 is trained using new supervised techniques that are combined with traditional supervised fine-tuning (SFT) and reinforcement learning based on human feedback (RLHF) methods. These improvements improve model controllability, understanding of nuances, and natural dialog capabilities.

GPT-4.5 outperforms all previous GPT models in multiple benchmarks:

• exist Scientific Reasoning (GBQ) In terms of scoring, the score far exceeds the GPT-4.
• exist Mathematical skills (AIME) Excellent performance on the assessment.
• exist Code Understanding (SBench Verified) Significant gains have also been made in the mission.

🤔 GPT-4.5 Future Significance

GPT-4.5 represents the AI development of the new direction::

1. unsupervised learning + inference The combination of the two will give rise to even more powerful AI assistants.
2. have sb do sth AI is closer to the human mindsetThe "cold" conversational experience will be reduced.
3. Laying the groundwork for future AI agents, making AI smarter and more practical.

Although, the high cost of using GPT-4.5 may limit some users, in the future, I believe that with the further development of the technology and the reduction of the cost, it will bring AI closer to the human mind, so that AI can completely free human hands.

💡 Interesting point:
🔸 GPT-1 can't even answer "Why is the ocean salty?" can't even answer it, while GPT-4.5 has been able to give a precise and easy-to-understand explanation.GPT-1 was released by Open AI in 2018, and the current version of the AI can already help people generate rich articles, pictures, and videos, which shows how fast the iterative nature of AI technology is.

If you are eager to explore the cutting-edge mysteries of AI, you can experience the stunning experience brought by GPT - 4.5, the big model of GPT is still the most powerful one. Of course, you can also continue to wait, I believe the arrival of GPT - 5.0 is not too far away.
