Openai launched the GPT -4.5 model – What is new?

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 was on chatgpt pro

Good news for those who are waiting: GPT-4.5 Officially launched on ChatgPT Pro from today. In the coming week, this model will be expanded for users of chatgpt plus, team and Edu packages. This shows that Openai is trying to bring advanced technology to users quickly and widely.

Not only stopping at upgrading performance, the model is also improved to communicate more naturally. Users describe it as a companion “warm, intuitive and friendly”. This is the result of Openai expanding the ability to learn non -monitoring, helping the model identification model, creating connections and understanding the user's intentions better than ever.

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.
