Talk to Cartesia speech-to-text about Cartesia speech-to-text. Cartesia launched a streaming STT model today, called Ink-Whisper, that's optimized for realtime voice AI. Pipecat AI has launch-day support for this new model, so I figured I'd talk to the model about itself.

Introducing Cartesia Ink-Whisper on Vapi! Slow STT ruins conversations. With Ink-Whisper, just one line in your Vapi config gets you: • Faster, streaming-optimized transcripts • Better handling of background noise and accents Start using it on Vapi today.

Tokenization has been the final barrier to truly end-to-end language models. We developed the H-Net: a hierarchical network that replaces tokenization with a dynamic chunking process directly inside the model, automatically discovering and operating over meaningful units of data

Tokenization is just a special case of "chunking" - building low-level data into high-level abstractions - which is in turn fundamental to intelligence. Our new architecture, which enables hierarchical *dynamic chunking*, is not only tokenizer-free, but simply scales better.
