Since this a resource is for Qwen 3, a different license was added by default here, I'm working to adjust that<h2 id="why-a-bridge">Why a bridge?</h2>Current ComfyUI installs ship transformers 5.x. Qwen3-TTS needs transformers 4.57.3:<ul><li>The official <code>qwen-tts</code> package does not import on transformers 5.</li><li>Nodes that patch around this can load, but may produce garbled or incoherent audio.</li></ul>A Python process can only load one version of a package, so both cannot live in ComfyUI's environment. This node keeps Qwen3-TTS in its own virtual environment and runs it as a separate process. The node is the bridge: you work in ComfyUI as usual, and it hands each job to the TTS environment and returns the audio.Nothing is installed into ComfyUI's environment.<blockquote>⚠️ Not a copy-and-paste install.</blockquote>So, the rest of the details are on <a target="_blank" rel="ugc" href="https://github.com/sd123git/ComfyUI-Qwen3TTS-Bridge/tree/main#comfyui-qwen3tts-bridge">https://github.com/sd123git/ComfyUI-Qwen3TTS-Bridge/tree/main#comfyui-qwen3tts-bridge </a>rather than copy/pasting here.This bridge is a baseline, with planned expansion to include the voice design and clone modes.
