How It Works

  • Advanced Neural Networks: DeepL utilises deep learning based on convolutional neural networks (CNNs), which process entire sentences in parallel for faster, more natural translations.
  • Extensive Training Data: AI models are trained on billions of high-quality bilingual sentences, meticulously collected by custom web crawlers.
  • Refined Training Methodology: The network continuously improves by comparing its own translations with training data and adjusting weights for accuracy.
  • Efficient Network Architecture: High translation quality is achieved with a smaller, faster network through efficient parameter use.
  • High-Performance Infrastructure: Translations are generated using a 5.1 petaflops supercomputer, powered by hydropower in Iceland, enabling high-volume processing within seconds.
