NVIDIA has released Audex (Nemotron-Labs-Audex-30B-A3B), a unified audio-text large language model. It understands and generates both audio and speech. It also keeps the text intelligence of its backbone. The checkpoints, along with a smaller Audex-2B, are released under a noncommercial license.
Most multimodal models pay a text tax. When labs add audio or vision output, text benchmarks often drop. NVIDIA research team reports this even for speech-only output models. Audex is designed to avoid that regression.
TL;DR
Audex is a single 30B-A3B MoE model that handles audio in and out.
Audio inputs enter the text embedding space; audio outputs are treated like text tokens.
