ERNIE 4.5 is Here: Baidu Launches a New Generation of Multimodal AI Ace with Comprehensively Upgraded Model Capabilities!
AI is no longer just a chatbot! Baidu’s latest ERNIE 4.5 series is an “all-around player” that can see, hear, read, and think. With its innovative MoE architecture, it demonstrates amazing capabilities in text, images, and video, while also achieving high performance and lightweight deployment. Now, let’s unveil its mysteries together!
Have you ever wondered what else artificial intelligence (AI) can do besides chatting with you? What if it could not only “read” thousands of books like a human but also “see” the whole world, even gaining insights from a picture or a video that you might have missed?
This sounds like a scene from a sci-fi movie, but now, Baidu has made a stunning debut with its latest ace—ERNIE 4.5, telling us that all of this has become a reality! This is not just a minor update, but a brand-new family of large-scale multimodal models, ready to subvert all your imaginations about AI.
The Secret of the AI Brain: ERNIE 4.5’s “Expert Team”
So, what unique skills does ERNIE 4.5 have that make it so “all-powerful”?
The answer lies in its unique “brain”—an innovative Heterogeneous Mixture-of-Experts (MoE) architecture.
The name sounds professional, but you can think of it as a highly efficient “dream team of experts.” The team includes “linguists” who specialize in processing text and are well-read, “art connoisseurs” with sharp eyes who can gain insights into the details of images and videos, and, of course, a group of interdisciplinary “generalists” responsible for coordination.
When a task comes, ERNIE 4.5 acts like a brilliant project manager, assigning the task to the most suitable expert. But what’s even more brilliant is that these experts don’t work alone; they share knowledge and learn from each other. In this way, the model can strengthen its grasp of text while deeply understanding images, truly achieving a balance between “literary and martial arts” without neglecting either.
For example, when you show it a picture full of ancient characters, it can not only identify that it is seal script but also tell you that the text is from Zhuge Liang’s “Former Memorial to the Throne,” and analyze its historical background and calligraphic art in detail. This level of deep understanding is not something that simple “literacy” can achieve!
The Super AI Development Plan: The Advanced Path from Top Student to All-Around Master
How is such a powerful model “forged”? The learning process of ERNIE 4.5 is simply an elite-level development plan.
It has absorbed massive amounts of data from the global internet, academic papers, images, videos, and more. To ensure that what it learns is “solid stuff,” the Baidu team has also established a strict screening mechanism and even introduced a “human-computer collaboration” process to repeatedly polish and ensure the quality of the data.
The entire training process is gradual and steady:
- Phase 1: Text-only training. First, build a solid language foundation to become an eloquent and knowledgeable “language master.”
- Phase 2: Vision-only training. Then, concentrate on “seeing the world” and learn to understand the rich connotations of images and videos.
- Phase 3: Multimodal joint training. Finally, perfectly integrate language and visual abilities, allowing it to learn cross-disciplinary thinking and reasoning, becoming a true “all-around player.”
To ensure this massive training process runs smoothly, ERNIE 4.5 also introduced a data manager called REEAO, which ensures the accuracy and repeatability of data processing. Doesn’t that sound like a super librarian?
Fast, Fierce, and Accurate: Not Just Smart, but Also Runs at Lightning Speed!
No matter how powerful a model is, if it runs like an old ox pulling a cart, it’s hard to put its skills to use. ERNIE 4.5 pursues the ultimate in performance, truly achieving “fast, fierce, and accurate.”
Behind this is the strong support of Baidu’s own PaddlePaddle deep learning framework and a series of cutting-edge technologies. They have pushed hardware performance to the limit through hybrid parallel strategies, FP8 mixed-precision training, and other techniques!
What’s even more surprising is that even with its massive scale, ERNIE 4.5 can be deployed in a lightweight manner. Through advanced quantization and compression techniques, the largest model can even be deployed on a single server with just a few GPUs. This means that top-tier AI technology is no longer the exclusive patent of large enterprises, and more people will have the opportunity to experience its power.
The Proof is in the Pudding: ERNIE 4.5’s Hardcore Track Record
Talk is cheap, so how does ERNIE 4.5 actually perform? In several international authoritative benchmark tests, it competed with top models like GPT-4.1 and DeepSeek-V3, and achieved leading results on many metrics!
- Knowledge and Reasoning: Whether it’s math problems that require rigorous logic or reasoning questions that test common sense, ERNIE 4.5 has shown super strength, surpassing strong competitors in 22 out of 28 benchmark tests.
- Instruction Following: It can accurately understand and execute complex user instructions, thanks to its well-designed reward system, which makes it more “understanding” of people’s intentions.
- Multimodal Applications: Give it a medical report, and it can quickly organize it into a table; give it a video, and it can generate accurate subtitles and locate key frames. These applications, which are close to real life, demonstrate its strong ability to solve practical problems.
Even the lightweight models with smaller parameter scales can show amazing competitiveness in math and reasoning tasks, perfectly interpreting what it means to be “high-performance and high-cost-effective”!
Making AI No Longer Distant: Your Exclusive AI Toolbox
The best part is that Baidu has chosen to share this powerful force with the world! All models, weights, and development toolkits of ERNIE 4.5 are fully open-sourced.
They have launched two super useful tools:
- ERNIEKit: A professional development toolkit with a full range of functions from training, fine-tuning to compression, and even provides a visual interface, allowing you to play with AI easily with “zero code.”
- FastDeploy: A tool born for efficient deployment, supporting multiple hardware, allowing ERNIE 4.5 to run at high speed on various platforms.
