# Audio8 TTS Preview 0.6B deploy: async-chunk streaming slow_ar -> codec_decoder.

# Model: Audio8/Audio8-TTS-Preview-0.6b (model_type = "arktts").

#
|
|
# trust_remote_code is deliberately OFF: the checkpoint ships an `auto_map`, and
|
|
# transformers prefers remote code over registered classes when it is enabled,
|
|
# which would bypass vllm-omni's Audio8TTSConfig (the Qwen2-shaped view that
|
|
# Qwen2Model needs). The tokenizer is a plain PreTrainedTokenizerFast and needs
|
|
# no remote code either.
