# Audex 30B-A3B (nvidia/Nemotron-Labs-Audex-30B-A3B) TTS deploy.
|
|
#
|
|
# Same pipeline/topology/token space as the 2B (audex_tts.yaml); the thinker
|
|
# is the hybrid Mamba+MoE NemotronHForCausalLM (~60 GB bf16), so:
|
|
# * enable_prefix_caching: false — hybrid Mamba stage.
|
|
# * Single H100 80GB layout: thinker 0.85 + decoder 0.08 share GPU 0.
|
|
# If weights + state do not fit (long sequences OOM), set
|
|
# tensor_parallel_size: 2 on stage 0 and move stage 1 to devices "2".
|
|
# * CUDA graphs stay ON for stage 0: the hybrid Mamba+MoE thinker
|
|
# captures cleanly and review benchmarks measured ~7x lower TTS RTF
|
|
# vs enforce_eager (0.30 vs 2.08 single-stream), on par with the 2B
|
|
# and NVIDIA's reference demo.
|
|
# * Classifier-free guidance quality (en-24, self-transcribed ASR CER):
|
|
# baseline cfg=1.0 -> 0.72%; guided cfg=1.5 at temperature 0.1 -> 0.72%
|
|
# (gate: guided <= baseline, PASS). Note the 30B's best guided
|
|
# temperature is 0.1 (the yaml default) — unlike the 2B's 0.05, which
|
|
# measured 0.79% here. The serving layer currently injects 0.05 for
|
|
# guided requests on all sizes; acceptable (still within the anchor
|
|
# +2pp standing gate) but a size-aware refinement is a known follow-up.
|
|
# ALWAYS pass this yaml explicitly (--deploy-config): bare serve of the
|
|
# 30B repo auto-detects the shared model_type and lands on the 2B-tuned yaml.
