Overview

CTranslate2 is an optimized inference engine originally built for neural machine translation.

It supports efficient quantization and batching for Transformer models.

Still relevant for translation and smaller model serving.

Features

  • INT8/FP16 quantization
  • Dynamic batching
  • CPU and GPU
  • Multi-threading
