## Notes

Chinese and English only; max 3,000 input characters; output up to 240 s for podcasts, 120 s otherwise. Comparable to ByteDance Seed Audio 1.0 (Jul 2026) and StepAudio 3 Gen. Sibling TTS model Qwen-Audio-3.1-TTS (plain TTS, ~70% cheaper than 3.0) exists but its exact API id was not verified: as of 2026-09-29 the international Model Studio docs (models page, qwen-tts page) list only qwen-audio-3.0-tts-flash / -plus, and neither qwen-audio-3.1-tts-flash/-plus nor an ASR-Next id resolves on QwenCloud (404). Verified 3.1 ASR ids: qwen-audio-3.1-asr-flash(-streaming/-filetrans). Update 2026-10-25: qwen-audio-3.1-tts-plus and qwen-audio-3.1-tts-flash are now listed in the Model Studio docs and pricing page; see qwen-audio-3-1-tts-plus.

Scene-level audio creation (audiobooks, podcasts, games, ads) rather than plain TTS.
