Ink Whisper

cartesia/ink-whisper

Launched June 10, 2025, Ink-Whisper was Cartesia's first speech-to-text model: a streaming-tuned variant of OpenAI's Whisper (large-v3-turbo baseline) with dynamic chunking. Now an older model behind Ink 2, it covers about 100 languages and alone handles batch transcription.
