Hugging Face and Cerebras Launch Open-Source Stack for Voice AI

🎙 Real-time Voice AI: A New Open-Source Stack

Hugging Face and Cerebras have introduced a modular system for creating voice AI agents with minimal latency. The stack combines Nvidia Parakeet for recognition, multimodal Gemma 4 31B (via fast Cerebras inference), and Alibaba Qwen3TTS for speech synthesis. This technology is already being used in Reachy Mini robots for live dialogue.

🌍 The transition to open modular stacks allows for reducing latency to the levels required for Embodied AI (robotics), where instantaneous reaction is critical.

👤 It is now possible to create high-speed voice assistants using open models, making personal AI agents more accessible and responsive.
