CacheDit

CacheDit is not supported by StepFun 1.1. CacheDit's core mechanism is exploiting temporal redundancy between adjacent denoising timesteps — step t=0.93 produces nearly identical block outputs as step t=0.97. NextStep-1.1 doesn't have this loop structure. Its outer loop is autoregressive token generation, where each step produces a genuinely different spatial token. There's no "adjacent timesteps are similar" property to exploit.

CPU Offloading

The current StepFun model are using the remote code and it doesn't have the transformer, transformer_2, dit attrs which are needed for swapping, so cpu-offload is not applicable. A followup PR to modularize the StepFun model definition into transformer, transformer_2, dit can enable cpu offloading.

TODO

Make all the model definitions/tokenizers local so we don't use remote ones. Currently we are pulling them from remote huggingface source and this is why cpu offloading is not supported since there are no transformer, transformer_2, dit attrs that's needed for swapping.

+        if cfg != 1.0 and cfg_img != 1.0:  # use both image and text CFG
+            w, h = images[0].size
+            captions = captions + [


Guard cfg_img path when no images are provided

When cfg_img != 1.0 this branch unconditionally reads images[0].size. In text-to-image use (the pipeline always passes images=None), any non‑1 cfg_img (which the CLI allows via --cfg_img) triggers an AttributeError before sampling. This makes prompt‑only generation fail for users who try image CFG; either gate this with a clear error or use the requested (height, width) instead of indexing images.

+            images,
+            num_images_per_prompt,


Respect requested num_outputs_per_prompt

The pipeline never overrides num_images_per_prompt from req.num_outputs_per_prompt, so Omni.generate(..., num_outputs_per_prompt=N) still produces just one image per prompt. This becomes visible because DiffusionEngine splits the returned image list based on request.num_outputs_per_prompt, leading to missing/empty images for requests expecting multiple outputs. Align this with other pipelines by pulling req.num_outputs_per_prompt before building captions and decoding.

Nice one, it would be even better if it could inherit from cache-dit.

Nice one, it would be even better if it could inherit from cache-dit.

I'd like to, probably we could add it as a follow up task and I'll take it later.

hsliuustc0106 · 2026-01-11T15:51:52Z

we have asked engineers from StepFun to review this PR, this one looks good to them

sniper35 · 2026-01-11T19:55:22Z

Had a final end to end test on the test script and added an additional example output. @hsliuustc0106 Please let me know if it's ready to be merged. Thanks!

 from vllm_omni.utils.platform_utils import is_npu, is_rocm

 # ruff: noqa: E402
-REPO_ROOT = Path(__file__).resolve().parents[2]


NextStep’s remote code does from utils.misc import LargeInt; https://huggingface.co/stepfun-ai/NextStep-1.1/blob/main/utils/misc.py .With .../tests ahead of the model folder on sys.path, Python can resolve utils to tests/utils.py (a module, not a package), which triggers the ci error of error: No module named 'utils.misc'; 'utils' is not a package.

@hsliuustc0106 I tested the latest code on a B200 and all tests passed. The latest buildkite failed due to OOM because stepfun-ai/NextStep-1.1 model needs more than 60GB VRAM to load the weights. I didn't find any smaller quantized model to fit into the test machine(24GB VRAM). Any suggestions here like can we skip unit tests for this model or assign a bigger machine for larger models?

hsliuustc0106 · 2026-01-14T08:00:32Z

add to supported models,
fix DCO
rm the CI for this model, bc we are going to support latest models from stepfun shortly
compare the inference latency with orignal implementation for stepfun
please check whether CacheDit can help accelerate
please check whether enable-cpu-offload can help reduce memory usage
please add memory usage guidance under examples markdown
please test whether online supports

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