Top 7 AI Models That Will "Take the World By Storm" in 2025

The year 2025 marks a major step forward in the global artificial intelligence (AI) race. AI models are being developed and updated at a dizzying pace, not only by giants like OpenAI, Google, Anthropic or Elon Musk's xAI but also by ambitious startups from China and Europe.

However, with a series of new names and versions constantly being released, tracking and choosing the right AI model is not easy for both ordinary users and experts. To help you have the most comprehensive and updated overview, below is a list of the 7 most prominent AI models in 2025 , let's find out!

1. OpenAI GPT-4.5 Orion

OpenAI has officially launched GPT-4.5 Orion, its largest and most advanced language model to date. With significantly expanded training scales in both the pre-training and post-training stages, GPT-4.5 provides faster, more accurate, and more flexible information processing than previous versions.

The highlight of GPT-4.5 is its focus on unsupervised learning, which allows the model to automatically detect and learn complex data patterns without manual intervention. As a result, GPT-4.5 can generate coherent, natural responses, while better connecting information and demonstrating superior creative thinking in many situations.

According to the research team at OpenAI, GPT-4.5 is equipped with “deeper world knowledge” and “higher emotional intelligence,” which helps increase the ability to understand context and improve the user communication experience. In particular, the phenomenon of “hallucination” when AI generates false information has been significantly reduced, improving the accuracy and reliability of the model.

In terms of features, GPT-4.5 supports many advanced tools such as: web search, canvas (visual working environment), the ability to upload files and images. These features help expand the scope of applications in work, study and content creation. However, a drawback is that GPT-4.5 is not yet compatible with AI Voice Mode , which limits voice interaction capabilities.

In its official announcement, OpenAI said that GPT-4.5 scored highly on language and text understanding tests, but was surpassed by the smaller o3-mini model in math problems, and fell slightly behind in science. This shows that, despite its superiority in language and emotion, GPT-4.5 still needs further improvement to conquer other specialized fields.

2. Claude Sonnet 3.7

Anthropic, an artificial intelligence company founded by former OpenAI employees, has officially introduced Claude 3.7 Sonnet , a significant upgrade from Claude 3.5. This model is notable for its outstanding performance in tasks requiring logical thinking , especially programming, mathematics, and processing complex requests.

The most outstanding feature of Claude 3.7 is its “hybrid reasoning” capability , which allows the model to combine contextual understanding and multi-step reasoning to provide accurate, logical, and easy-to-understand answers. Thanks to that, Claude 3.7 can not only handle simple questions but also effectively solve situations that require in-depth analysis and systematic thinking.

Currently, Claude 3.7 is available for free for standard users, while the Claude Pro package with priority access and advanced features costs $20/month, a competitive price in the AI ​​market.

What’s notable about Anthropic’s approach is that it’s distinctly different from competitors like OpenAI. While many companies separate reasoning, programming, and conversation models, Claude 3.7 integrates all of these capabilities into a single model . The goal, says Dianne Penn , Anthropic’s Product Lead, is to simplify the user experience by avoiding the need to choose the right model for each task.

Thanks to this design, users can simply ask questions or make requests in a natural way, whether it's asking for the time, writing an email, planning a trip, or analyzing data, and Claude 3.7 can handle it all without context switching or complex configuration.

The “all-in-one” approach makes Claude 3.7 more flexible, unified, and easy to use, especially suitable for those who want a consistent, smooth, and intelligent AI experience in all situations.

3. xAI Grok 3

Grok 3 is the latest AI model developed by xAI , a company founded by Elon Musk , with the goal of building an AI system capable of thinking like a human. Unlike models that focus on pure conversation, Grok 3 is optimized for fields that require high logical thinking such as mathematics, science, and programming . The model demonstrates strong reasoning capabilities , allowing for smooth processing of complex queries that require multiple consecutive inference steps.

In addition to its fast response speed and natural expression, Grok 3 also impressed with its support for Vietnamese , expanding its accessibility to users in many markets, including Vietnam. Elon Musk once humorously declared: "Grok 3 is currently free until our servers crash" , showing the level of interest and large traffic, although the time of application of the free policy has not been clearly determined.

Another notable point is the appearance of DeepSearch - a new research tool integrated into Grok 3. DeepSearch is designed to enhance the ability to search, analyze and reason , helping the model not only provide answers but also clearly explain the reasoning behind each result . This helps users understand more deeply, thereby strengthening the reliability in the process of using AI for learning, research and professional work.

According to Business Insider , xAI started developing DeepSearch in late 2024, showing the company's long-term strategy and serious investment in upgrading the thinking capacity and transparency of the Grok system.

With a focus on argumentation, critical thinking, and transparency, Grok 3 and DeepSearch are not only a communication support tool but are also gradually becoming a reliable AI research assistant , aiming to serve users in more in-depth and intellectual tasks.

4. DeepSeek R1

DeepSeek is an AI company from China, founded in 2023 by Liang Wenfeng with the orientation of developing large open source language models . Backed by High-Flyer investment fund, DeepSeek chooses a transparent strategy by publicizing source code and technical documentation, allowing the community to easily access, edit and use according to needs.

On January 10, 2025 , the company launched DeepSeek R1 – their first chatbot model. Notably, after only 17 days, R1 surpassed ChatGPT to become the most downloaded free application on the App Store in the US. This explosion even caused Nvidia's stock to drop 18% , showing the significant influence of R1 on the global AI market.

DeepSeek R1 stands out with its ability to self-check accuracy before responding , limiting the "illusion" phenomenon often seen in other models. Although processing time may be slower, high reliability in complex tasks such as math, physics, and programming makes R1 highly appreciated.

According to DeepSeek, the model applies techniques such as reinforcement learning and chained inference , which improve thinking and reasoning. In terms of performance, R1 is said to be on par with leading models such as GPT-4.5 on many intensive tasks.

Users can access R1 via the company's website or API , making its applications in research, development, and academia more flexible and accessible than ever.

5. Mistral the Cat

Mistral's Le Chat is designed as a multimedia personal assistant, featuring faster responses than any other AI chatbot. Users can choose between a free or paid version, depending on their needs. According to Le Monde's review, despite its impressive performance, Le Chat still has certain flaws when compared to ChatGPT.

Le Chat is highly rated for its ability to access the internet to provide answers with the latest data, along with the ability to upload PDFs and images for analysis. In addition, the application also supports many useful tools such as canvas, code interpreter and image creation capabilities. 

One notable limitation of Le Chat is that each feature seems to have its own limitations, typically web accessibility. After a few searches, Le Chat's bot would give a message that it could not retrieve updated information because it had reached its web search limit. This significantly affected the user experience, and Mistral AI needs to fix it soon or provide a specific explanation to improve the stability of the application.

6. OpenAI Operator

Developed as an intelligent personal assistant, OpenAI Operator is capable of automatically performing tasks such as online shopping. Specifically, OpenAI Operator provides the ability to directly interact with the user interface on the web by clicking, typing, and navigating through menus. Thanks to that, this tool can perform a series of tasks such as booking travel tickets, booking restaurants, supporting online shopping with filtering features, searching for products, filling in information, and handling repetitive tasks. 

Not only that, OpenAI Operator also helps manage personal workflows by storing prompts or settings that users frequently perform on a certain website. In particular, this tool is capable of handling multiple tasks simultaneously and automatically correcting errors when encountering difficulties, bringing an effective experience to users.

Despite being deployed via the ChatGPT Pro plan, which costs $200 per month, the model has been controversial. For example, a Washington Post editor had trouble getting Operator to automatically purchase a dozen eggs for $31 on his credit card, highlighting the potential risks of making decisions on his own.

7. Google Gemini 2.0 Pro Experimental

Gemini 2.0 comes in two distinct versions, each offering its own unique advantages. While Gemini 2.0 Flash focuses on speed and processing efficiency, Gemini 2.0 Pro Experimental impresses with its superior encryption capabilities and ability to handle complex tasks.
