Model Overview

Description:

This model is used to transcribe short-form audio files and is designed to be compatible with OpenAI's sequential long-form transcription algorithm. Whisper is a pre-trained model for automatic speech recognition (ASR) and speech translation. Trained on 680k hours of labeled data, Whisper models demonstrate a strong ability to generalize to many datasets and domains without the need for fine-tuning. Whisper-large-v3 is one of the 5 configurations of the model with 1550M parameters.
This model version is optimized to run with NVIDIA TensorRT-LLM. This model is ready for commercial use.
