TL;DR:

Baidu recently released ERNIE 4.5-21B-A3B-Base, a powerful open-source LLM

You can launch ERNIE 4.5-21B directly on DigitalOcean GPU Droplets with only 1-click - deploy in the cloud console

We put ERNIE 4.5-21B to the test for translation and it outperformed models like Qwen3 - check out our demo

What is ERNIE 4.5 21B?

ERNIE (Enhanced Representation through kNowledge IntEgration) 4.5-21B-A3B-Base represents a significant leap in large language model development. Originating from Baidu’s extensive research, this model is celebrated for its unique knowledge-enhanced architecture, which allows for robust performance across complex natural language processing tasks, including sophisticated text generation, nuanced conversational AI, and comprehensive summarization. Its ability to integrate real-world knowledge into its understanding sets it apart, making it a compelling choice for intricate AI applications. Deploying ERNIE 4.5-21B on DigitalOcean empowers you to rapidly prototype and scale applications powered by a model that goes beyond surface-level text processing, without the overhead of intricate infrastructure configuration.

ERNIE 4.5 21B in Action: Rapid translation from English to Chinese with Python

ERNIE 4.5-21B is praised for its advanced multimodal capabilities, handling text, images, audio, and video, as well as its remarkable computational efficiency, allowing you to save significantly on AI infrastructure deployment costs while achieving high performance.

We specifically put it to the test for translation, using an ERNIE 4.5 1-Click GPU Droplet to rapidly translate English files to Chinese. ERNIE mastered the task, translating line-by-line in mere moments. This efficient, line-by-line translation can be adapted for various file types, including markdown and doc files.
