2025 is considered an important milestone for AI artificial intelligence, when a series of technological breakthroughs not only improve model performance but also change the way people perceive the path of AI development.
From energy-saving reasoning, top-notch solving capabilities to outer space model training, AI is entering a new phase, where foundational research is being focused on again.
One of the most shocking events is the appearance of DeepSeek R1, an open source AI model from China.
Launched in early 2025, DeepSeek R1 shows that inference models can achieve high performance without a huge computing infrastructure.
Taking advantage of techniques such as model distillation, expert mixing and advanced attention mechanisms has helped DeepSeek exploit less modern GPUs effectively.
This challenges the long-standing view that advanced AI always comes with huge training costs, while opening up a more sustainable approach to energy.
In the field of mathematics, 2025 also recorded historical progress when AI models of OpenAI and Google DeepMind achieved achievements equivalent to gold medals at the International Mathematical Olympiad.
This success shows that AI is not only good at creating text or images, but also has the ability to reason abstractly at a high level.
Researchers expect these models to support solving complex problems in encryption, theoretical physics or space exploration.
In the creative field, AI image creation tools have taken a long step forward. OpenAI's Images for ChatGPT feature has created a Ghibli style art fever on social networks, attracting hundreds of millions of users.
The use of the GPT-4o model with the self-recovery image creation method helps the image become clearer, more detailed and easier to control, marking a clear maturity of multi-modal AI.
Along with that, 2025 witnessed the rise of AI agents, which are systems that can automatically perform tasks.
To solve the limitation when actors have to read the internet designed for humans, the Model Context Protocol (MCP) is being promoted for widespread application. MCP becoming an open standard, supported by many large technology corporations, is considered an important step in reshaping how AI interacts with the digital world.
The most bold breakthrough probably comes from space. At the end of 2025, Starcloud announced that it had successfully trained an AI model on a GPU placed on a low-orbit satellite.
This experiment is not only technically significant, but also suggests the possibility of building AI infrastructure outside Earth, reducing pressure on resources and the environment.
Progress shows that 2025 not only marks an expansion in scale, but also an important shift as AI becomes smarter, more efficient and more diverse. According to many researchers, the field of artificial intelligence is returning to the core of research, where the quality of thinking, algorithms and model design is equally valued, even surpassing the size race.
This approach is expected to lay the foundation for profound changes in AI in 2026 and the following periods.
