Qwen3 Omni 30B A3B Instruct — Hardware Requirements & GPU Compatibility
ChatQwen3-Omni-30B-A3B-Instruct is Alibaba's flagship omni-modal model, a mixture-of-experts Thinker-Talker system that processes text, images, audio, and video and responds with real-time streaming text and speech. Its text backbone routes across 128 experts with 8 active per token, roughly 3 billion active parameters out of around 35 billion total, since it keeps both the "thinker" and the speech-generating "talker" plus its audio codec resident in memory. It supports 119 text languages, 19 spoken input languages, and 10 spoken output languages, and needs a high-end consumer GPU or multi-GPU setup once quantized. Its language backbone supports a 65,536 token context window. It is released under the Apache 2.0 license, and was published in September 2025 as the instruct counterpart to Qwen3-Omni-30B-A3B-Thinking, which drops the talker to focus on text output with chain-of-thought reasoning.
