 Intelligent java (IntelliJava) is the ultimate tool for Java developers looking to integrate with the latest language models and deep learning frameworks. The library provides a simple and intuitive API with convenient methods for sending text input to models like GPT-3 and DALL·E, and receiving generated text or images in return. With just a few lines of code, you can easily access the power of cutting-edge AI models to enhance your projects.
