via “autoregressive token decoding with sliding-window context and beam search”

OpenAI speech recognition CLI.

Fast transformer inference engine — INT8 quantization, C++ core, Whisper/Llama support.

Unique: Multiple decoding strategies (greedy, beam search, sampling) compiled into the inference graph at conversion time with support for advanced features like length penalties, coverage penalties, and vocabulary constraints. Unlike runtime decoding in PyTorch, CTranslate2 decoding is optimized at the C++ level with minimal overhead.

vs others: Comparable decoding quality to PyTorch with faster execution due to C++ implementation and optimized beam search with dynamic batching.
