Cartesia· Sonic / InkDeveloper tool

Cartesia announced Edge, an open-source library for on-device state space models; Rene, an open-source 1.3B parameter language model; and Sonic On-Device, a generative voice model in private beta, as part of its on-device intelligence update.

From the source

We’re now excited to bring state space models to your device. As part of this release, we’re announcing: Edge , an open-source (Apache 2.0) library to support the research and release of highly efficient SSMs for on-device applications across accelerators and environments. Edge brings together open-weights SSM language models, including Rene , in one place and makes them available for Apple hardware through our new SSM optimized Metal kernels. Rene , an open-source 1.3B parameter language model pretrained from scratch with a hybrid Mamba-2 SSM backbone, and tailored to on-device inference. Sonic On-Device , in private beta. Sonic On-Device is the first ultra-realistic generative voice model that supports low latency real-time streaming on device, with unlimited voices and instant voice cloning.
