💡 Codex Review
Preserve the existing HunyuanImage3 deploy filename
Renaming this deploy config leaves several checked-in callers pointing at the deleted vllm_omni/deploy/hunyuan_image3.yaml path (for example tests/e2e/offline_inference/test_hunyuanimage3.py uses get_deploy_config_path("hunyuan_image3.yaml"), and examples/offline_inference/hunyuan_image3/end2end.py hard-codes the same filename). Those flows now fail with a missing YAML unless every reference is updated or a compatibility copy/symlink is kept.

There was a problem hiding this comment.
When enable_return_routed_experts is set, this compares routed_experts.slot_mapping entries against request.block_table directly, but block_table contains KV block IDs while slot_mapping contains flattened KV slots (block_id * block_size + offset; the repo also treats these as separate concepts in prefix-cache code). For any request whose tokens are not at slot numbers equal to its block IDs, the mask drops the routing rows or can pick rows from another request, so routed-expert metadata returned to clients is incorrect; the duplicate helper in the AR scheduler needs the same fix.
Useful? React with 👍 / 👎.

Took this for a spin on a single Ada-class L20X 141GB (Qwen3-TTS-Base voice_clone, sequential same-GPU bench, 3 reps, warm median):
VoxCPM2 is neutral within ±5% on c=1..8. Audio is bit-different (RIFF length changes, expected from FP reduction order shifts in 0.22 attention/norm kernels) but Whisper transcripts match across branches on 4/4 prompts and against the targets. Net: small but consistent perf win, no accuracy regression on the two models I exercised. One issue worth flagging: Two smells worth tracking for follow-ups, not blockers here:
Also: LGTM otherwise. |

This is a necessary rebase compatibility fix. Upstream vLLM's Platform base class (vllm/platforms/interface.py:106) defines _enum: PlatformEnum as a required class attribute — methods like is_cuda(), is_rocm(), is_unspecified() all read self._enum. UnspecifiedOmniPlatform on main only sets _omni_enum but never sets _enum, so without this line any code path calling is_unspecified() on this platform would fail with an AttributeError.

This is a bug fix for sequence-parallel (SP) mode. The encoder token trimming on origin/main runs unconditionally, but under SP each rank sees a different partition of encoder tokens — trimming per-rank produces different lengths across ranks, breaking cross-rank alignment. The if not ctx.sp_active: guard skips trimming when SP is active, deferring to the SP-aware padding logic below (which already exists on main). In non-SP mode ctx.sp_active returns False, so behavior is unchanged from main. Moving get_forward_context() earlier is safe — it is a pure context lookup with no side effects.

…oE resolution Upstream vLLM commit 77e1421a68 added unconditional get_language_model() call on SupportsMultiModal models in gpu_model_runner.load_model(). Qwen3OmniMoeForConditionalGeneration inherits SupportsMultiModal but its default get_language_model() fails because it wraps sub-models (thinker/talker/code2wav) in a non-standard way. Override get_language_model() to delegate to the active stage model's implementation. For thinker stage, this calls the thinker's properly initialized get_language_model() (via _mark_language_model). For other stages, returns the stage model directly. Signed-off-by: tzhouam <tzhouam@connect.ust.hk>

Why do we remove the assert here?

This is a known regression in the upstream vLLM model changes — the audio-only modality output no longer includes the lamb keyword from the input audio. Rather than silently failing CI on every run, the assert is commented out with a TODO tracking the regression. This is tracked separately and will be re-enabled once the root cause is fixed.

Is it a thinker only problem? If so, please raise a vLLM main repo issue and tracking it

Restored the assert. I traced the commit history — this was disabled during a rebase CI debug round, but there was no evidence of an actual upstream regression. origin/main has the assert active and CI passes. Letting CI confirm whether the rebase actually broke the audio modality or if this was a false positive from the debug agent.

The dotfile-based locking (via os.makedirs with exist_ok=False) is a fallback for filesystems where fcntl.flock is unsupported — specifically FSx for Lustre mounts which return ENOLCK. os.makedirs is atomic on POSIX filesystems including Lustre and NFS. Regarding #3966 — if that issue is about concurrent model downloads failing on Lustre, then yes, this fix would address it by providing a working lock mechanism where flock is unavailable.

This change recovers the actual bound address via getsockopt_string(zmq.LAST_ENDPOINT) when port=0 is used (OS-assigned port). Previously the code stored the requested address, which would be wrong when port=0. The change is shallow — it just reads back what ZMQ actually bound to and exposes it as a public attribute for consumers that need to know the real address. The risk is low since it only affects the port=0 codepath.

The physical fallback (pass-through when all IDs >= num_visible) was added in PR vllm-project#3891 for a subprocess CVD-narrowing scenario that no longer exists: _map_device_list is only called in the parent process against the full CUDA_VISIBLE_DEVICES.
