Hugging Face and Cerebras bring Gemma 4 to real-time voice AI
We're on a journey to advance and democratize artificial intelligence through open source and open science. Back to Articles a]:hidden"> Hugging Face and Cerebras bring Gemma 4 to real-time voice AI Published July 1, 2026 Update on GitHub Upvote 9 +3 Amir Mahla A-Mahla Follow Andres Marafioti andito Follow Leandro von Werra lvwerra Follow Saurabh Vyas vyassaurabh Follow cerebras For voice AI, latency is a critical parameter. Developers have made tremendous progress in model quality, but the user experience is still often limited by response times.
Key Takeaways
- Hugging Face and Cerebras are changing that experience.
Today, we demonstrate what becomes possible when an open, modular voice AI architecture is paired with industry-leading inference speed.
- Each part of the system is modular, open, and replaceable, making it easy for developers to adapt the stack for different assistants, robots, products, or research projects.
This creates a fully open speech-to-speech loop: The architecture brings together the strength of the open-source AI ecosystem: Cerebras for fast inference, Google DeepMind's Gemma 4 31B for the language model, and Qwen for text-to-speech.
- By making inference dramatically faster and more stable, Cerebras allows the rest of the Hugging Face pipeline to shine.
- It is what makes the interaction feel alive.
The motivation to use Cerebras is therefore not simply cost reduction.
- We invite developers to explore the demo, experiment with the code, and help shape what comes next for real-time voice AI.

Hugging Face and Cerebras are changing that experience. Today, we demonstrate what becomes possible when an open, modular voice AI architecture is paired with industry-leading inference speed. The result is a speech-to-speech experience that feels dramatically more natural.
Instead of waiting for an AI to respond, conversations flow with the responsiveness users expect from human interaction. Architecture: an Open, Cascaded Speech-to-Speech stack The demo is built as a real-time speech-to-speech pipeline. Each part of the system is modular, open, and replaceable, making it easy for developers to adapt the stack for different assistants, robots, products, or research projects.
This creates a fully open speech-to-speech loop: The architecture brings together the strength of the open-source AI ecosystem: Cerebras for fast inference, Google DeepMind's Gemma 4 31B for the language model, and Qwen for text-to-speech. Every layer can be inspected, modified, and extended by the developers Cerebras and Hugging Face Partnership Today, some production systems see a reasonable median latency while still experiencing frustrating multi-second delays at the P95. Those delays become even more noticeable when tool calls or multimodal steps require multiple turns.
