Provider Notes

Qwen3-Omni transcription is batch-only. Qwen3 TTS HTTP models accept up to 600 characters and return WAV, PCM, MP3, Opus, mu-law, or A-law: the provider's native 24 kHz WAV is passed through, and every other format is transcoded while streaming. The realtime model slugs use Alibaba's shared Qwen TTS WebSocket host, independently of the workspace-dedicated realtime ASR and Omni host, and forward Alibaba's native input buffer and response events. Flash models use model-specific built-in voice sets; Instruct models add common instructions and optimize_instructions; VC and VD models require a custom Alibaba voice ID created for that exact enrollment model. Legacy token-billed qwen-tts models are not available.
