Gradium

Gradium is an AI organization focused on speech technology, developing systems that convert written text into natural-sounding audio. Its work centers on text-to-speech synthesis, a domain where quality of voice, clarity, and responsiveness matter as much as raw model scale.

On Venice, Gradium is represented by a single offering: Gradium TTS, a dedicated text-to-speech model introduced in 2026. Rather than spreading across text, image, or video generation, the catalog is purpose-built around voice output, making it a specialized pick for applications that need spoken audio from text input.

With a narrow but clear focus, Gradium stands apart from general-purpose model labs. Gradium TTS gives developers and users a straightforward way to add voice synthesis to their workflows without adopting a broader multi-model stack.
