Kokoro** is an open-weight TTS model with 82 million parameters. Despite its lightweight architecture, it delivers comparable quality to larger models while being significantly faster and more cost-efficient. With Apache-licensed weights, Kokoro can be deployed anywhere from production environments to personal projects. 🐈 **GitHub**: https://github.com/hexgrad/kokoro 🚀 **Demo**: https://hf.co/spaces/hexgrad/Kokoro-TTS [!NOTE] As of April 2025, the market rate of Kokoro served over API is **under $1 per million characters of text input**, or under $0.06 per hour of audio output.
