# Covo-Audio-Chat deploy: fused_thinker_talker → code2wav on a single GPU. # Verified on 1x A100-80G. # # Fields omitted from a stage fall back to StageDeployConfig defaults (see # vllm_omni/config/stage_config.py). Non-default choices in this file: # * async_chunk: false — pipeline defines no async-chunk processor funcs. # * Stage 1 max_num_batched_tokens=2048, max_model_len=2048 — audio code # sequences are short; the 32k default is unnecessary here. # * Stage 1 dtype: float32 — BigVGAN vocoder weights are fp32; the default # bf16 triggers mat1/mat2 dtype mismatch during warmup. # * Stage 1 enforce_eager: true — the code2wav forward pass performs a # GPU→CPU sync (int(code.flatten()[0]) in covo_audio.py) which is # illegal during CUDA graph capture. async_chunk: false trust_remote_code: true stages: - stage_id: 0 max_num_seqs: 1 gpu_memory_utilization: 0.5 mm_processor_cache_gb: 0 devices: "0" default_sampling_params: temperature: 0.0 top_p: 1.0 top_k: -1 max_tokens: 2048 seed: 42 repetition_penalty: 1.1 - stage_id: 1 max_num_seqs: 1 gpu_memory_utilization: 0.2 enforce_eager: true dtype: float32 max_num_batched_tokens: 2048 max_model_len: 2048 mm_processor_cache_gb: 0 devices: "0" default_sampling_params: temperature: 0.0 top_p: 1.0 top_k: -1 max_tokens: 2048 seed: 42 repetition_penalty: 1.1
