Sesame Releases Open Source Voice AI Model with Few Safety Restrictions

AI company Sesame has open-sourced CSM-1B, the base model behind its realistic virtual assistant Maya, under a permissive Apache 2.0 license allowing commercial use. The 1 billion parameter model generates audio from text and audio inputs using residual vector quantization technology, but lacks meaningful safeguards against voice cloning or misuse, relying instead on an honor system that urges developers to avoid harmful applications.
