Whisper Benchmark Viz

Article to accompany this code Whisper Showdown @ Medium

This repository contains code for visualizing benchmarks comparing the execution time and cost for two different transcription models: whisper.cpp (CPU-based) and openai-whisper (GPU-based using PyTorch). The code generates two charts: one for average execution time and the other for the log-transformed price/performance ratio.

Installation

  1. Clone the repository:
git clone https://github.com/seandearnaley/whisper_benchmark_viz.git
cd whisper_benchmark_viz
  1. Install Poetry if you haven't already:
curl -sSL https://install.python-poetry.org | python3 -
  1. Install dependencies using Poetry:
poetry install

Usage

  1. Activate the virtual environment:
poetry shell
  1. Run the main.py script to generate the charts:
python main.py

This will display two charts: one for the average execution time (in minutes) and the other for the log-transformed price/performance ratio.

Data

The benchmark data is stored in the data.json file. You can modify this file to include your own benchmark data for different computer configurations and test cases.

The JSON file contains the following fields:

  • test_data: A list of lists containing the execution times for each computer and test.
  • computer_names: A list of computer names.
  • power_usage_watts_per_computer: A list of power usage in watts for each computer.
  • computer_rental_cost_per_hour: A list of computer rental costs per hour.
  • cost_per_kwh: The cost per kilowatt-hour for electricity.
  • test_names: A list of test names.
