This resolves a remote tokenizer repository to a local ModelScope snapshot before load_custom_tokenizer() is called. load_path is the explicit tokenizer path/ID when supplied, otherwise the model path/ID. This branch runs only when ModelScope is enabled and the path does not already exist locally. Despite its historical download_hf_partial name, the helper dispatches to the selected hub.
Why this extra step is gated on ModelScope: The normal Transformers tokenizer path already understands Hugging Face repository IDs: AutoTokenizer.from_pretrained() resolves the requested tokenizer files through Hugging Face's download/cache machinery. It does not need a separate snapshot download here. TRTLLM_USE_MODELSCOPE is a TensorRT-LLM setting; Transformers does not interpret it, and this PR deliberately does not globally patch Hugging Face APIs. Passing an unresolved ModelScope ID to an HF-backed tokenizer would therefore still query Hugging Face, even if the weights came from ModelScope. Resolving that ID through ModelScope first and passing the resulting local directory makes the existing tokenizer loader read the intended files.
The same resolution is done before the custom-tokenizer call because load_custom_tokenizer() delegates to the selected class's from_pretrained(); it does not implement ModelScope routing itself. With ModelScope disabled, this PR preserves the existing HF/custom-tokenizer behavior and each custom tokenizer's existing input requirements. Local directories and initialized tokenizer objects need no additional hub resolution.
vLLM and SGLang use the same approach:
- vLLM's tokenizer resolver checks
VLLM_USE_MODELSCOPE, leaves existing local paths alone, lazily imports ModelScope, and downloads the tokenizer under a file lock while forwarding revision/offline settings. It excludes.pt,.safetensors, and.binweights via the legacyignore_file_patternAPI, then replacestokenizer_namewith the local snapshot path. - SGLang's
SGLANG_USE_MODELSCOPEgate invokeshandle_modelscope_paths(). That helper reuses local/cache paths or downloads a ModelScope snapshot and substitutes the resolved paths. Its tokenizer download excludes*.binand*.safetensorswithignore_patterns.
This PR uses the same gated remote-ID-to-local-directory handoff, with an allow-list of tokenizer/configuration formats instead of the weight exclusions above. The filter APIs are not identical: this PR uses native glob allow_patterns, while the cited vLLM code uses the legacy regex-capable ignore_file_pattern.
The patterns select common tokenizer/configuration assets:
*.json: tokenizer definitions, tokenizer/model configuration, vocabulary, special tokens, and added tokens.*.jinja,*.j2: chat templates.*.model: SentencePiece tokenizer models.*.py: repository-provided tokenizer code; downloading it does not itself execute it, and the existing loader'strust_remote_codehandling is preserved.*.tiktoken: tiktoken vocabulary/rank files.*.txt: text vocabularies and BPE merge files.
These are glob filters, not a download of the full checkpoint: ordinary model-weight files such as *.safetensors, *.bin, and *.pt are not selected. revision=self.tokenizer_revision preserves the requested tokenizer revision, and the returned local directory is passed to the custom-tokenizer loader. This avoids handing that loader an unresolved ModelScope ID or causing a separate Hugging Face tokenizer lookup when Hugging Face may be inaccessible. Existing local paths and already-created tokenizer objects keep their existing handling.
This is an allow-list of common formats, not a guarantee for every custom tokenizer: a tokenizer that needs additional file types would require extending the list or providing a prepared local directory. The explicit remote-tokenizer branch below uses the same patterns for the same reason.

This makes the default tokenizer use the same resolved local snapshot as the model. self._hf_model_dir comes from CachedModelLoader; despite its historical name, it can hold either a Hugging Face or a ModelScope snapshot. self.args.model may still be the original remote ID, such as Qwen/Qwen3-0.6B.
Passing that original ID directly to the Hugging Face/Transformers tokenizer loader can trigger a separate Hugging Face lookup. Without this local-snapshot preference, ModelScope weights could be paired with a separately resolved Hugging Face tokenizer, or tokenizer loading could fail when Hugging Face is inaccessible.
The or self.args.model fallback preserves loading paths where _hf_model_dir has not been populated. It falls back to the original model argument; it is not a retry against Hugging Face after a failed ModelScope download.
Explicitly supplied tokenizers have already been initialized and return above this line, so this selection does not override them. The LoRA tokenizer lookup below also retains its existing precedence; model_path is the fallback when it does not supply a tokenizer. The model/generation-config loaders below use the same local-snapshot preference to keep those assets aligned as well.

Approving — the comments below are optional touch-ups, not blockers.
The HF default path is unchanged and the ModelScope branch is confined to one function, which makes this easy to reason about. I checked the call order — every _try_load_* runs after super()._build_model() (llm.py:2040) — so _hf_model_dir is populated by then, and the multimodal input processor already got the resolved dir. I also confirmed against ModelScope 1.20's snapshot_download that all four kwargs you pass exist and revision=None resolves to the latest valid revision, so there's no default-branch mismatch.
Two things to address before merge, both about the boundary of the feature rather than the code:
The routing is partial, and the docs read as if it isn't. With TRTLLM_USE_MODELSCOPE=1:
backend="_autodeploy"ignores it entirely —CachedModelLoader.__call__returns early for_autodeploybefore any download, and_torch/auto_deploy/models/hf.py:485calls HFsnapshot_downloaddirectly. The tokenizer would come from ModelScope while the weights come from HF.trtllm-benchcalls HFsnapshot_downloaddirectly (bench/benchmark/throughput.py:395,low_latency.py:248).modeling_vila.py:118usesrepo_exists/snapshot_downloadagainst HF.
I'm not asking you to route these here — one PR, one concern. But the doc section should say which paths are covered (PyTorch backend model + spec model + tokenizer/config) and which aren't, so a user on a ModelScope-only repo gets a predictable failure instead of a confusing one.
Env var vs. MPI workers. _node_download_hf_model fans out through submit_sync, and use_modelscope() reads os.environ in the worker process. Local spawn inherits it; a multi-node mpirun/Ray launch may not, and then nodes split between hubs silently. An LlmArgs field would serialize to workers, but it pulls in the golden-manifest/telemetry review process — the env var is the lighter choice. Please document that the variable must be exported on every node.
Docs nit: the new section sits between ### 1. and ### 2., breaking the numbering. The patch_hub() / ignore_file_pattern-regex paragraph is implementation rationale — better as a comment on _snapshot_download than on a user-facing page.

This catches any ImportError raised while importing modelscope, including one coming from a transitive dependency missing inside the package, and relabels it "ModelScope is not installed" — which sends the user to a pip install that won't fix anything.
Guard on the failing module name and re-raise otherwise:

In this branch load_path may have fallen back to self.model (line 5268) when no explicit tokenizer was given, but the download is always issued with self.tokenizer_revision. A user who set revision="v2" and left tokenizer_revision unset gets the model repo's default revision here, while download_hf_model later fetches revision="v2" for the same repo — two different snapshots feeding the tokenizer and the weights.
Pass self.tokenizer_revision if self.tokenizer else self.revision (or self.tokenizer_revision or self.revision).

This seven-element glob list is duplicated verbatim at line 5290. Lift it to a module-level constant (e.g. _TOKENIZER_FILE_PATTERNS) so the two branches can't drift — a tokenizer format added to one and not the other fails only on the path that wasn't updated.

This stubs out modelscope and the leaf module but leaves modelscope.hub alone. If modelscope is ever actually installed in the test image — which this PR's [modelscope] extra makes likely — and any earlier test imports it, modelscope.hub stays in sys.modules and from modelscope.hub.snapshot_download import ... resolves against the real package, so this test fails depending on ordering. Add monkeypatch.setitem(sys.modules, "modelscope.hub", None).

The new tests cover _snapshot_download well, but nothing exercises the two behavior changes most likely to regress Hugging Face users: the tokenizer pre-download branch in llm_args.validate_and_init_tokenizer, and _try_load_tokenizer/_try_load_hf_model_config now preferring self._hf_model_dir over self.args.model. A test asserting that a local tokenizer path is passed through untouched when TRTLLM_USE_MODELSCOPE=1 (the Path(...).exists() guard) would be cheap and catches the case where someone's local dir happens to shadow a repo-id-shaped string.

Description
Closes #19463.
Human
ModelScope is an extremely popular model hub in China. Due to this popularity, similar to other popular engines like vllm modelscope integration & sglang modelscope integration , this PR adds optional modelscope integration into TRTLLM. via the opt in flag of
export TRTLLM_USE_MODELSCOPE=1with default to huggingface.We have tested it with
Qwen/Qwen3-0.6Band verified that it passes evals.This PR only adds modelscope as an optional (not required) dependency
This PR probably isn't perfect and we are open to your feedback & suggestions on this PR. (tagging our NVIDIA rep @kedarpotdar-nv & @Ankur-singh
AI
Add ModelScope as an opt-in source for remote model and tokenizer repositories in the TensorRT-LLM LLM API and
trtllm-serve. This lets users load a supported checkpoint hosted on ModelScope, including in environments where accessing Hugging Face is difficult, while retaining Hugging Face as the default.For example, with
TRTLLM_USE_MODELSCOPE=true,Qwen/Qwen3-0.6Bis downloaded through ModelScope and its resolved local snapshot is used for the default tokenizer and model/generation configuration. Existing local model paths continue to work. The change selects the source of checkpoint files; it does not introduce a new inference backend or replace Transformers/Hugging Face libraries.Installation and opt-in behavior
First install a TensorRT-LLM build containing this change, following the existing installation instructions or source-build instructions.
For an existing compatible installation or container, install the optional SDK and enable ModelScope before starting the process:
The same switch applies to Python usage:
The packaging change in
setup.pyaddsmodelscope>=1.20underextras_require["modelscope"]. Once a package release containing this change is available, users can request it with:python -m pip install 'tensorrt_llm[modelscope]'The SDK is not added to the required dependency list. It is imported lazily when a ModelScope download is requested. Installing the extra alone does not switch hubs;
TRTLLM_USE_MODELSCOPE=trueor1enables it. Unset the variable or set it tofalseto retain Hugging Face downloads. If the switch is enabled but the SDK is missing, the download boundary raises an actionableImportErrorwith the install command.Installing the SDK alone does not retrofit this feature into an older TensorRT-LLM release. In particular, the
1.3.0rc27validation image below required a source-matched runtime backport. No published release containing this PR is assumed here.Implementation
The change spans six files: the download utilities, tokenizer argument resolution, LLM snapshot consumers, optional packaging extra, LLM API documentation, and download regression tests.
Select the hub at the existing download boundary.
llmapi/utils.pyaddsuse_modelscope()and a shared_snapshot_download()dispatcher.download_hf_model()anddownload_hf_partial()retain their signatures,Pathreturn values, and file locks. The dispatcher forwards revisions, allow/ignore filters, andlocal_files_onlyderived fromHF_HUB_OFFLINE. The existingoriginal/**/*full-download exclusion is preserved. The Hugging Face branch continues to call its original SDK; selecting ModelScope does not silently fall back to Hugging Face on failure.Use the downloaded snapshot consistently.
llmapi/llm.pyusesself._hf_model_dir or self.args.modelfor the default tokenizer and configuration loaders. Despite its historical name,_hf_model_dirholds the local snapshot returned by the selected hub. Without this, ModelScope weights could be paired with a separately resolved Hugging Face tokenizer, or tokenizer loading could fail when Hugging Face is inaccessible. Explicit tokenizer objects return earlier, and existing LoRA tokenizer precedence is preserved. The fallback retains behavior for paths without a resolved snapshot, such as AutoDeploy; it does not claim comprehensive AutoDeploy ModelScope support. The local-snapshot preference also applies when HF is selected.Resolve explicit remote tokenizers before constructing them.
llmapi/llm_args.pyresolves nonlocal string/Pathtokenizer IDs throughdownload_hf_partial()when ModelScope is enabled. This includes the custom-tokenizer loading path, which requires a local directory. It forwardstokenizer_revisionand allows*.json,*.jinja,*.j2,*.model,*.py,*.tiktoken, and*.txt, avoiding the usual.safetensors,.bin, and.ptweight files. Local paths and constructed tokenizer objects are preserved; existingtrust_remote_codehandling remains in control of code loading.Reuse existing model-resolution callers. Configuration-only downloads already use
download_hf_partial(). The existingCachedModelLoaderroutes target and speculative-model downloads throughdownload_hf_model(), so those callers inherit hub selection without a second downloader. Existing worker coordination and local-path detection remain in place. No newLlmArgsfields are introduced.Keep redirection scoped. The implementation does not call ModelScope's process-wide
patch_hub(). It redirects these TensorRT-LLM download paths and passes local directories to downstream loaders. Applications that download datasets or other assets through separate HF consumers must configure those consumers separately. Repository IDs and revision names must be valid on the selected hub; this does not synchronize repositories across hubs.The LLM API documentation describes installation, the switch, local paths, tokenizer-only resolution, and these scope boundaries.
Relationship to vLLM and SGLang
Both projects already resolve remote ModelScope IDs to local snapshots before passing them to model/tokenizer loaders. The links below are pinned to the inspected commits.
maybe_download_from_modelscope()checksVLLM_USE_MODELSCOPE, lazily imports the SDK, preserves local paths, locks downloads, and forwards revision/offline settings. Itstokenizer resolverdownloads tokenizer assets while excluding common weight formats, then substitutes the local tokenizer path.SGLANG_USE_MODELSCOPEgate invokeshandle_modelscope_paths(). It resolves model, tokenizer, and speculative-draft paths, reuses local/cache paths, and downloads missing snapshots. Its tokenizer branch excludes*.binand*.safetensors. Packaging differs: at this commit, SGLang listsmodelscopeamong its regular dependencies, while this TensorRT-LLM PR adds an optional extra.This PR follows that explicit hub-selection/local-path approach. For tokenizer-only downloads it uses an allow-list of known tokenizer/config file types. It uses ModelScope's native
allow_patterns/ignore_patternsglob arguments; the cited vLLM implementation also uses the legacyignore_file_patternAPI, whose regex behavior is not interchangeable. The ModelScope 1.20.0 signature and filtering implementation support the chosen arguments at the declared minimum version.Test Coverage
Download regression tests and SDK compatibility
The four added tests cover ModelScope allow-filter/revision/offline forwarding, the full-download ignore filter, HF as the default, and the missing optional dependency error. They passed locally with TensorRT/CUDA bootstrap imports stubbed, and also against the actual installed TensorRT-LLM package with the release-compatible backport on H100.
A real ModelScope 1.20.0 SDK probe, with repository/file transport mocked and socket connections disabled, verified glob filtering and revision forwarding. Repository pre-commit checks and Python compilation passed for the changed files. Fork CodeQL checks passed on
c5c002e64b.H100 cold-cache integration sweep
InferenceX PR #3324 ran a successful full PR sweep using
Qwen/Qwen3-0.6B, BF16, TP1, andnvcr.io/nvidia/tensorrt-llm/release:1.3.0rc27. The image matches source tagv1.3.0rc27, commit6e1cc953c071b8a9055b03ef2ae4ee0bc4c645c4. The backport and waiver document precisely what was applied. Runtime SDKs were pinned tomodelscope==1.40.1andmodelscope-hub==0.4.3.The final audit links the evidence and records checks of raw samples, expected concurrency metadata, all seven server/job logs, and matching aggregates. It also discloses that the run-statistics job sampled 6/7 before the final eval finished; final job records show 7/7 passed. InferenceX CI separately passed 1,880 tests with one skipped; that is InferenceX coverage, not the full TensorRT-LLM test suite.
Controlled HF versus ModelScope accuracy comparison
A separate H100 experiment ran stock HF, patched HF with ModelScope disabled, and patched ModelScope. Each arm evaluated all 1,319 GSM8K questions twice at c32 and twice at c64: 12 full evaluations. Prompts, targets, generation settings, and inference-asset hashes were checked; all responses were nonempty. Strict-score means were:
These results do not establish identical accuracy. ModelScope minus patched-HF strict accuracy was −0.0758 percentage points at c32 and −1.5921 at c64. The c64 paired-question approximate 95% interval was [−2.9478, −0.2365] points. Patched HF's own c64 repeats differed by 1.8196 points. Fixed arm order, one model/GPU, and two repeats limit causal interpretation; these question-level intervals do not capture all server-run variability. Passing InferenceX's documented 0.60 integration floor is not an equivalence claim.
The complete comparison and artifact details include individual scores, response-level differences, and before/after hashes. The archived verifier-only correction allowed the two empty Transformers bookkeeping files; it did not change the running model server or inference settings.
