Hugging Face and Cerebras bring Gemma 4 to real-time voice AI
Get smart on it
For voice AI systems, response time is a critical problem that affects how natural conversations feel. Two companies partnered to demonstrate a speech-to-speech system using open-source components where fast inference on one company's hardware allows conversations to flow with responsiveness similar to human interaction, avoiding the multi-second delays that currently frustrate users. The system works as a modular pipeline that takes speech input, processes it through speech recognition and a language model, generates text-to-speech output, and delivers a spoken response, with each component being replaceable by developers. This approach is already being used to power robots currently deployed in the field, where responsiveness is essential to making interactions feel natural.

Using Lift to Turn Research PDFs into Structured JSON with Controlled, Schema-Guided Field-Level Evaluation
In this tutorial, we build a complete PDF-to-structured-data extraction workflow around Lift, with a focus on controlled evaluation rather than a simple demo run. We begin by preparing a Colab-compatible GPU environment, selecting the appropriate precision mode for the available hardware, and patching model loading to ensure the Lift backend runs reliably even on constrained 16 GB GPUs via 4-bit NF4 quantization. From there, we generate synthetic multi-page research reports with deliberately pl
