A new, efficient text-to-speech model called Kani TTS 370M has been released on the Hugging Face Hub. Developed by the user `nineninesix`, the model contains 370 million parameters, offering a relatively lightweight option for generating high-quality, multilingual speech.

The model is based on the Language-Free Modeling for Multilingual Text-To-Speech (LFM2) architecture. This approach allows it to handle multiple languages without relying on explicit language identification tags during training or inference. This design choice can make a model more flexible and scalable for diverse linguistic applications, learning to synthesize different languages from a mixed dataset.

Kani TTS 370M's compact size is its most notable feature. In a field often dominated by multi-billion parameter models, a smaller footprint makes it more accessible for researchers and developers with limited computational resources. This could enable its use in on-device applications or lower-cost cloud deployments where efficiency is a primary concern.

The model weights and usage instructions are publicly available on its [Hugging Face repository](https://huggingface.co/nineninesix/kani-tts-370m). While the weights are accessible, the license is listed as "All rights reserved," indicating that it is not intended for commercial use without permission from the creator.
