Notes

Artificial Analysis TTS arena (https://artificialanalysis.ai/text-to-speech/leaderboard), read 2026-10-25: rank #3, Elo 1307, listed at $19.3 per 1M characters, which does not match Alibaba’s current list price ($30/1M Singapore, $20/1M Beijing); AA’s figure is close to the Beijing price but the gap is unexplained. Ids verified 2026-10-25 (they were not yet in the docs on 2026-09-29): qwen-audio-3.1-tts-plus and qwen-audio-3.1-tts-flash on the qwen-tts page (updated 2026-10-21), the pricing page and QwenCloud. Plus rate limit 180 RPM; sample voice longanhuan_v3.1. Singapore free quota 10,000 characters (Plus) / 1M tokens (Flash) for 90 days. Exact release date of these two ids not on the docs; date is the Qwen-Audio-3.1 launch. Language list, max input length and snapshot ids not stated. Not on OpenRouter (qwen/qwen-audio-3.1-tts-plus 404; 3.0-tts-plus is listed there). Siblings: qwen-audio-3-1-tts-next, qwen-audio-3-1-asr, qwen-audio-3-1-realtime. Predecessor: qwen-audio-3-0-tts.
