Highlights

This release introduces the WhisperKit Local Server! A OpenAI-compatible Vapor based HTTP server that can be run via CLI or as a subprocess.

Try it out with the following command:

:::swift
BUILD_ALL=1 swift run whisperkit-cli serve

Key Features

  • Local Server: OpenAI-compatible /v1/audio/transcriptions and /v1/audio/translations endpoints
  • Transcription Streaming: Server-sent events as files get transcribed
  • Response Formats: Support for json, verbose_json
  • Timestamp Granularities: Word-level and segment-level timestamps
  • Client Examples: Python, Swift, and Bash with curl

You can also use the Makefile command make build-local-server to generate an exectuable that can be bundled in your electron or tauri apps without needing any native integration.

There are also several bugfixes and quality of life improvements relating to tokenizer loading and VAD access.
