The appearance of GPT-4.5the latest language model from Openai, is considered to be a significant improvement compared to the predecessor GPT-4O, GPT-4.5 offers a series of outstanding features, from more natural communication ability to 10 times more powerful processing performance. Let's explore to see what GPT-4.5 is special and why it is making the global technology community so excited!

What is GPT-4.5?

Openai Proudly declare GPT-4.5 is the largest and most knowledge model that they have ever developed until now. However, unlike models of the O-Series series (O1, O3, O3-Mini) focusing on arguments and solving STEM problems (science, technology, engineering, mathematics), GPT-4.5 is designed versatile, towards optimizing many different types of tasks.

From creative writing, natural dialogue to handling images and multimodal files (multimodal), GPT-4.5 promises to bring a smoother and more effective experience. A notable point is that the “hallucination” ratio-the phenomenon of AI to create false information-has decreased significantly, from 61.8% at GPT-4O to 37.1%. Simultaneously, The accuracy of the model soared to 62.5%far beyond the number 38.2% of the previous version.

Outstanding performance of GPT-4.5

When placed on the comparative scale, GPT-4.5 shows a clear outstanding through standard evaluation tests:

• MMLU (14 languages): GPT-4.5 shows diverse language skills, far exceeding GPT-4O.
• SWE-BENCH VERIFIED (Solving the actual software error): reaching 38%, higher than 30.7% of the GPT-4O.
• SWE-Lancer (Economic software mission): score 32.6%, compared to 23.3% of GPT-4O.
• GPQA (science): reaching 71.4%, far ahead of the number of 53.6% of the GPT-4O.

However, if you expect GPT-4.5 to defeat inference models like O1 or O3 in logical argument, think again. Openai affirmed that the O-Series line still holds the leading position in the tasks that require complex thinking. However, with the goal of serving a variety of user needs, GPT-4.5 is still a formidable choice thanks to its flexibility and comprehensive efficiency.

Outstanding improvements of GPT-4.5

Not only stop at the number, GPT-4.5 also brings realistic improvements that users can feel immediately:

• With a higher emotional index, this model can understand and respond in a close way, like a real friend.
• Understand users' intentions, better analysis models and subtle expectations, helping to give more accurate answers.
• Multimonentical processing: uploading images, text and source codes, opening up unlimited creative potential.
• The content is less deviation, bringing higher reliability to professional users.
• Although not supported Voice modevideo or screen sharing, GPT-4.5 is still a big step in bringing who comes closer to everyday life.

GPT-4.5 and the future of GPT-5

The appearance of GPT-4.5 not only satisfies the current user but also arouses curiosity about GPT-5-the version that is expected to integrate the O3 reasoning model to create a more comprehensive AI system. According to some rumors, GPT-5 can be announced as soon as possible May 2025promising to bring new breakthroughs in the field of artificial intelligence.

While waiting for GPT-5, GPT-4.5 has proven that Openai is constantly innovating to meet the increasing demands of users. From writing, programming to resolving practical problems, GPT-4.5 is setting a new standard for versatile language models.

Conclusion

GPT-4.5 Not only is a simple upgrade but also a testament to Openai's ambition to shape AI future. With outstanding performance, natural communication and expanded knowledge, GPT-4.5 is opening a new era for versatile language models. While waiting for GPT-5, this is definitely a tool that you cannot ignore if you want to experience the power of modern AI.

GPT-4o is an advanced language model, the latest version of the ChatGPT product line developed by OpenAI, designed to understand and respond to human language naturally and intelligently.
