**Qhash-TTS** is an open-weight TTS model with 84 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, Qhash-TTS can be deployed anywhere from production environments to personal projects.
