Test Plan

Test 1
Omni online inference

vllm serve /workspace/models/Qwen3-Omni-30B-A3B-Instruct --omni --port 8014 --log-stats
python openai_chat_completion_client_for_multimodal_generation.py \
  --query-type use_video \
  --video-path t2v_out_1.mp4 \
  --model /workspace/models/Qwen3-Omni-30B-A3B-Instruct \
  --prompt "What are the main activities shown in this video?" 

Test 2
Omni offline inference
need to add --log-stats in run_multiple_prompts.sh

python end2end.py --output-wav output_audio \
                  --query-type text \
                  --txt-prompts text_prompts_10.txt \
                  --py-generator \
                  --log-stats
cd examples/offline_inference/qwen3_omni
bash run_multiple_prompts.sh

Test 3

vllm serve /workspace/models/Qwen-Image --omni --port 8014 --log-stats

curl -s http://localhost:8014/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{

P2 Badge Preserve stage generation time for sync orchestrator metrics

In _as_stage_request_stats, stage_gen_time_ms is always taken from accumulated_gen_time_ms.pop(req_id, 0.0) and the value provided in the metrics dict is ignored. That accumulator is only updated in the async pipeline; the synchronous Omni path never adds to it, so per-request stage timing (and any derived rates) become zero in non-async runs. This is a regression in metrics accuracy for synchronous serving; consider falling back to metrics.get("stage_gen_time_ms") when the accumulator is empty or populating the accumulator in the sync path.

P2 Badge Avoid dropping preprocess timing before stage stats exist

The preprocess time is recorded immediately after process_engine_inputs but before the next stage has produced any metrics. record_stage_preprocess_time only updates existing stage_events entries, so at this point there is no entry for next_stage_id, causing the value to be dropped and leaving preprocess_time_ms at 0 for all requests in async multi-stage runs. To make this metric usable, buffer it until on_stage_metrics creates the stage entry or move the recording to after metrics are emitted.

I am confuse about this result. in_flight_times refers to the network transmission time ? and tx_time_ms and rx_decode_time_ms is serialize/deserialize time? seems to take a lot of time.

please check it !

  • make_request_stats constructs StageRequestStats with stage_stats=None, but StageRequestStats.stage_stats is currently a required (non-Optional) field. This can lead to runtime errors if any downstream code expects a StageStats instance. Either make stage_stats optional in the dataclass (with a default), or always pass a StageStats value here (e.g., a zero/default instance) and update later if needed.

  • The metrics dict is created once and then passed to multiple OmniRequestOutput.from_diffusion(...) results. Since the dict is mutable and not copied, multiple outputs will share the same metrics object, so mutations on one output’s metrics will affect the others. Pass a per-output copy (or construct per-request metrics inside the loop) to keep outputs isolated.

* feat: add HyperCLOVAX-SEED-Omni-8B support

Model files:
- vllm_omni/diffusion/models/hyperclovax_vision/: vision decoder pipeline
  (HyperCLOVAXVisionPipeline) using flow matching diffusion + VisionTransformer
- vllm_omni/diffusion/models/hyperclovax_audio/: audio decoder pipeline
  (HyperCLOVAXAudioPipeline) using Unit-BigVGAN codec
- vllm_omni/model_executor/stage_input_processors/hyperclovax_seed_omni.py:
  thinker2vision_decoder and thinker2audio_decoder — extract discrete tokens from
  LLM output; truncate/pad vision codes to 729 (27x27) for decoder

Registry:
- vllm_omni/diffusion/registry.py: register HyperCLOVAXVisionPipeline and
  HyperCLOVAXAudioPipeline with post-process functions

Stage config:
- vllm_omni/model_executor/stage_configs/hcx_omni.yaml: 3-stage config
  Stage 0: LLM thinker (TP=4, GPUs 0-3), Stage 1: vision decoder (GPU 4),
  Stage 2: audio decoder (GPU 5)

Bug fixes for HyperCLOVAX compatibility:
- diffusion/request.py: add extra dict field to OmniDiffusionRequest so
  vision_tokens/audio_tokens from stage input processors reach the pipeline
- entrypoints/async_omni_diffusion.py: extract OmniTokensPrompt.additional_information
  into OmniDiffusionRequest.extra before creating request
- entrypoints/omni_stage.py: skip empty engine inputs (text-only requests where
  thinker2vision_decoder/thinker2audio_decoder return [])
- entrypoints/async_omni.py: handle skipped sentinel in _process_single_result
  so text-only requests complete without crashing on Stage 1/2

* fix: correct decoder params and HCX porting fixes

- hcx_omni.yaml: guidance_scale 3.5→0.75, num_inference_steps 30→50
  (matches OmniServe production defaults; 3.5 caused over-amplified
  autoguidance → shrunken/degraded output images)
- omni_stage.py: skip empty engine inputs for text-only requests
- async_omni_diffusion.py: extract OmniTokensPrompt.additional_information
  into OmniDiffusionRequest.extra (audio_tokens/vision_tokens)
- registry.py: HCX Omni diffusion model registration fix

* feat: HyperCLOVAX-SEED-Omni-8B stage pipeline and entrypoint fixes

* fix: change guidance_scale from 9.0 to 0.75 (autoguidance scale, OmniServe default)

* feat: add audio decoder Stage 2 to hcx_omni pipeline

- Wire HyperCLOVAXAudioPipeline as Stage 2 in hcx_omni.yaml
- GPU 5 assigned for audio decoder (Unit-BigVGAN / NCCosybigvganDecoder)
- Add runtime edge 0->2 (thinker -> audio decoder)
- Implement post-generation PCM chunk streaming for audio output
  (4800 samples / 200ms per SSE event @ 24kHz, int16 base64-encoded)

Refs: github.com/vllm-project/vllm-omni/pull/869 (already incorporated)

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: vllm version compatibility for HyperCLOVAX audio decoder startup

- config/model.py: try/except fallback for AttentionBackendEnum import
  (vllm.v1.attention.backends.registry absent in older vllm builds)
- pipeline_hyperclovax_audio.py: return actual named_parameters() from
  load_weights() when using MAR checkpoint so diffusers_loader strict
  check passes (weights loaded eagerly in __init__ via MAR extraction)
- qwen3_omni_moe_thinker.py, qwen2_5_omni_thinker.py: try/except stubs
  for check_interleaved_audio_video and merge_interleaved_embeddings
  which are absent in older vllm qwen2_5_omni_thinker; these symbols
  are only exercised by Qwen models, not HyperCLOVAX

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: add edge 1→2 and correct model key in hcx_omni.yaml Stage 2

- Add runtime edge from:1 to:2 (required for Stage-2 connector init;
  without it AsyncOrchestrator cannot route to audio decoder at runtime)
- Change model_subdir to model for Stage-2 engine_args to match
  total-poc working reference config

* fix: audio S2S output - handle diffusion outputs in _create_audio_choice

HyperCLOVAXAudioPipeline (diffusion) stores audio in multimodal_output
directly (OmniRequestOutput.from_diffusion), not in outputs[0].multimodal_output
like LLM pipelines. Fix three locations:

1. _create_audio_choice (non-streaming): use omni_outputs.multimodal_output
   when final_res.outputs is empty (diffusion path).
2. Streaming audio path: same fix for _final_res.outputs[0].
3. Both loops (for output in final_res.outputs): fall back to single
   synthetic choice at index 0 when outputs list is empty.
4. Handle bytes audio output from HyperCLOVAXAudioPipeline post-process
   (returns WAV bytes, not tensors like Qwen3-Omni).

Also fixes audio input (A2T) regression: skip diffusion prompt extraction
when mm_data has audio content (added in previous session).

* fix: parse WAV bytes with soundfile for uniform PCM chunk streaming

HyperCLOVAXAudioPipeline returns WAV bytes including 44-byte header.
The previous byte-offset splitting included the header in the first
chunk, corrupting it. Fix: parse with soundfile to get float32 PCM,
then convert to int16 chunks uniformly regardless of source type
(bytes or tensor).

Verified: 136 audio chunks x 200ms = 27.04s audio streamed correctly.

* feat: zero-shot TTS with speaker embedding from input audio

- serving_chat.py: extract last input_audio base64 from request messages
  and inject as ref_audio_b64 into engine_prompt dict
- thinker2audio_decoder: read ref_audio_b64 from prompt and pass as
  ref_audio_tokens to Stage 2 (HyperCLOVAXAudioPipeline)
- hcx_omni.yaml: switch Stage 2 to NCZSCosybigvganDecoder.mar (zero-shot)
  which uses ECAPA-TDNN speaker encoder instead of finetuned ID lookup

Pipeline: input audio -> ECAPA-TDNN -> speaker embedding -> BigVGAN synthesis
matching the voice characteristics of the original speaker.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* feat: wire audio decoder Stage 2 to hcx_omni pipeline and fix S2S flow

- Add Stage 2 (HyperCLOVAXAudioPipeline / NCZSCosybigvganDecoder) to hcx_omni.yaml
  with GPU 5, gpu_memory_utilization 0.4, edge 0->2 from thinker
- Fix thinker2audio_decoder: correct audio token range (128606-135167),
  remap to [0, 6561) for BigVGAN input, handle empty token case gracefully
- Fix pipeline_hyperclovax_audio.py post_process_func signature and
  incorporate PR#869 BUG FIX patches for stable audio generation

* fix: use finetuned audio decoder and fix transformers_modules deserialization

- hcx_omni.yaml: switch Stage 2 from NCZSCosybigvganDecoder (zero-shot,
  ECAPA-TDNN) to NCCosybigvganDecoder (finetuned, nn.Embedding speaker id).
  Zero-shot decoder required ref_audio (mel spectrogram) which is unavailable
  for text-only requests and incompatible with finetuned decoder path.

- pipeline_hyperclovax_audio.py: guard ref_audio processing with
  'not self.bigvgan.finetune' — finetuned decoder has no ECAPA-TDNN encoder,
  so passing ref_audio bytes would crash with 'expected 100 channels'.

- omni_stage.py: add HuggingFace modules cache (~/.cache/huggingface/modules)
  to sys.path before queue.get_nowait() in try_collect(). Stage-0 pickles
  outputs containing custom classes from transformers_modules (trust_remote_code),
  but the API server process doesn't have this path, causing deserialization
  failures that silently drop Stage-0 outputs.

* fix: restore zero-shot speaker cloning with fallback for text-only requests

- hcx_omni.yaml: revert to NCZSCosybigvganDecoder.mar (zero-shot ECAPA-TDNN)
  for voice-preserving S2S synthesis. NCCosybigvganDecoder used a fixed
  integer speaker_id and lost the input speaker's voice.

- pipeline_hyperclovax_audio.py: add zero-mel fallback branch for
  finetune=False + ref_audio=None case. When a text-only request arrives
  (no input audio → no ref_audio), ECAPA-TDNN receives a zero mel tensor
  [1, num_mels, 64] instead of crashing with 'expected 100 channels'.
  S2S requests always have ref_audio so the zero-shot cloning path is
  unchanged.
