# Supported Models
2

3
vLLM supports [generative](./generative_models.md) and [pooling](./pooling_models.md) models across various tasks.
4
5
6
7
8
9
10
11

For each task, we list the model architectures that have been implemented in vLLM.
Alongside each architecture, we include some popular models that use it.

## Model Implementation

### vLLM

12
If vLLM natively supports a model, its implementation can be found in [vllm/model_executor/models](../../vllm/model_executor/models).
13

14
These models are what we list in [supported text models](#list-of-text-only-language-models) and [supported multimodal models](#list-of-multimodal-language-models).
15
16
17

### Transformers

18
vLLM also supports model implementations that are available in Transformers. You should expect the performance of a Transformers model implementation used in vLLM to be within <5% of the performance of a dedicated vLLM model implementation. We call this feature the "Transformers modeling backend".
19

20
Currently, the Transformers modeling backend works for the following:
21
22

- Modalities: embedding models, language models and vision-language models*
23
- Architectures: encoder-only, decoder-only, mixture-of-experts
24
25
26
27
- Attention types: full attention and/or sliding attention

_*Vision-language models currently accept only image inputs. Support for video inputs will be added in a future release._

28
If the Transformers model implementation follows all the steps in [writing a custom model](#writing-custom-models) then, when used with the Transformers modeling backend, it will be compatible with the following features of vLLM:
29

30
- All the features listed in the [compatibility matrix](../features/README.md#feature-x-feature)
31
- Any combination of the following vLLM parallelisation schemes:
32
    - Data parallel
33
    - Tensor parallel
34
35
    - Expert parallel
    - Pipeline parallel
36
37

Checking if the modeling backend is Transformers is as simple as:
38
39
40

```python
from vllm import LLM
41
llm = LLM(model=...)  # Name or path of your model
42
43
44
llm.apply_model(lambda model: print(type(model)))
```

45
If the printed type starts with `Transformers...` then it's using the Transformers model implementation!
46

47
If a model has a vLLM implementation but you would prefer to use the Transformers implementation via the Transformers modeling backend, set `model_impl="transformers"` for [offline inference](../serving/offline_inference.md) or `--model-impl transformers` for the [online serving](../serving/openai_compatible_server.md).
48

49
!!! note
50
    For vision-language models, if you are loading with `dtype="auto"`, vLLM loads the whole model with config's `dtype` if it exists. In contrast the native Transformers will respect the `dtype` attribute of each backbone in the model. That might cause a slight difference in performance.
51

52
53
#### Custom models

54
If a model is neither supported natively by vLLM nor Transformers, it can still be used in vLLM!
55

56
For a model to be compatible with the Transformers modeling backend for vLLM it must:
57
58

- be a Transformers compatible custom model (see [Transformers - Customizing models](https://huggingface.co/docs/transformers/en/custom_models)):
59
60
    - The model directory must have the correct structure (e.g. `config.json` is present).
    - `config.json` must contain `auto_map.AutoModel`.
61
- be a Transformers modeling backend for vLLM compatible model (see [Writing custom models](#writing-custom-models)):
62
    - Customisation should be done in the base model (e.g. in `MyModel`, not `MyModelForCausalLM`).
63
64
65

If the compatible model is:

66
67
- on the Hugging Face Model Hub, simply set `trust_remote_code=True` for [offline-inference](../serving/offline_inference.md) or `--trust-remote-code` for the [openai-compatible-server](../serving/openai_compatible_server.md).
- in a local directory, simply pass directory path to `model=<MODEL_DIR>` for [offline-inference](../serving/offline_inference.md) or `vllm serve <MODEL_DIR>` for the [openai-compatible-server](../serving/openai_compatible_server.md).
68

69
This means that, with the Transformers modeling backend for vLLM, new models can be used before they are officially supported in Transformers or vLLM!
70
71
72

#### Writing custom models

73
This section details the necessary modifications to make to a Transformers compatible custom model that make it compatible with the Transformers modeling backend for vLLM. (We assume that a Transformers compatible custom model has already been created, see [Transformers - Customizing models](https://huggingface.co/docs/transformers/en/custom_models)).
74

75
To make your model compatible with the Transformers modeling backend, it needs:
76
77

1. `kwargs` passed down through all modules from `MyModel` to `MyAttention`.
78
79
80
81
    - If your model is encoder-only:
        1. Add `is_causal = False` to `MyAttention`.
    - If your model is mixture-of-experts (MoE):
        1. Your sparse MoE block must have an attribute called `experts`.
82
83
84
        2. The class of `experts` (`MyExperts`) must either:
            - Inherit from `nn.ModuleList` (naive).
            - Or contain all 3D `nn.Parameters` (packed).
85
        3. `MyExperts.forward` must accept `hidden_states`, `top_k_index`, `top_k_weights`.
86
87
88
2. `MyAttention` must use `ALL_ATTENTION_FUNCTIONS` to call attention.
3. `MyModel` must contain `_supports_attention_backend = True`.

```

133
134
</details>

135
136
137
138
Here is what happens in the background when this model is loaded:

1. The config is loaded.
2. `MyModel` Python class is loaded from the `auto_map` in config, and we check that the model `is_backend_compatible()`.
139
3. `MyModel` is loaded into one of the Transformers modeling backend classes in [vllm/model_executor/models/transformers](../../vllm/model_executor/models/transformers) which sets `self.config._attn_implementation = "vllm"` so that vLLM's attention layer is used.
140
141
142
143
144

That's it!

For your model to be compatible with vLLM's tensor parallel and/or pipeline parallel features, you must add `base_model_tp_plan` and/or `base_model_pp_plan` to your model's config class:

from transformers import PretrainedConfig

class MyConfig(PretrainedConfig):
    base_model_tp_plan = {
        "layers.*.self_attn.k_proj": "colwise",
        "layers.*.self_attn.v_proj": "colwise",
        "layers.*.self_attn.o_proj": "rowwise",
        "layers.*.mlp.gate_proj": "colwise",
        "layers.*.mlp.up_proj": "colwise",
        "layers.*.mlp.down_proj": "rowwise",
    }
    base_model_pp_plan = {
        "embed_tokens": (["input_ids"], ["inputs_embeds"]),
        "layers": (["hidden_states", "attention_mask"], ["hidden_states"]),
        "norm": (["hidden_states"], ["hidden_states"]),
    }
```

168
169
</details>

170
171
- `base_model_tp_plan` is a `dict` that maps fully qualified layer name patterns to tensor parallel styles (currently only `"colwise"` and `"rowwise"` are supported).
- `base_model_pp_plan` is a `dict` that maps direct child layer names to `tuple`s of `list`s of `str`s:
172
173
174
175
    - You only need to do this for layers which are not present on all pipeline stages
    - vLLM assumes that there will be only one `nn.ModuleList`, which is distributed across the pipeline stages
    - The `list` in the first element of the `tuple` contains the names of the input arguments
    - The `list` in the last element of the `tuple` contains the names of the variables the layer outputs to in your modeling code
176

### Plugins

Some model architectures are supported via vLLM plugins. These plugins extend vLLM's capabilities through the [plugin system](../design/plugin_system.md).

| Architecture | Models | Plugin Repository |
182
| ------------ | ------ | ----------------- |
183
| `BartForConditionalGeneration` | BART | [bart-plugin](https://github.com/vllm-project/bart-plugin) |
184
| `Florence2ForConditionalGeneration` | Florence-2 | [bart-plugin](https://github.com/vllm-project/bart-plugin) |
185
186
187

For other model architectures not natively supported, in particular for Encoder-Decoder models, we recommend following a similar pattern by implementing support through the plugin system.

## Loading a Model

### Hugging Face Hub

By default, vLLM loads models from [Hugging Face (HF) Hub](https://huggingface.co/models). To change the download path for models, you can set the `HF_HOME` environment variable; for more details, refer to [their official documentation](https://huggingface.co/docs/huggingface_hub/package_reference/environment_variables#hfhome).

To determine whether a given model is natively supported, you can check the `config.json` file inside the HF repository.
If the `"architectures"` field contains a model architecture listed below, then it should be natively supported.

Models do not _need_ to be natively supported to be used in vLLM.
198
The [Transformers modeling backend](#transformers) enables you to run models directly using their Transformers implementation (or even remote code on the Hugging Face Model Hub!).
199
200
201
202
203
204
205

!!! tip
    The easiest way to check if your model is really supported at runtime is to run the program below:

    ```python
    from vllm import LLM

206
207
    # For generative models (runner=generate) only
    llm = LLM(model=..., runner="generate")  # Name or path of your model
208
209
210
    output = llm.generate("Hello, my name is")
    print(output)

211
212
    # For pooling models (runner=pooling) only
    llm = LLM(model=..., runner="pooling")  # Name or path of your model
213
214
215
216
217
218
    output = llm.encode("Hello, my name is")
    print(output)
    ```

    If vLLM successfully returns text (for generative models) or hidden states (for pooling models), it indicates that your model is supported.

219
Otherwise, please refer to [Adding a New Model](../contributing/model/README.md) for instructions on how to implement your model in vLLM.
220
221
222
223
224
225
Alternatively, you can [open an issue on GitHub](https://github.com/vllm-project/vllm/issues/new/choose) to request vLLM support.

#### Download a model

If you prefer, you can use the Hugging Face CLI to [download a model](https://huggingface.co/docs/huggingface_hub/guides/cli#huggingface-cli-download) or specific files from a model repository:

226
```bash
227
# Download a model
228
hf download HuggingFaceH4/zephyr-7b-beta
229
230

# Specify a custom cache directory
231
hf download HuggingFaceH4/zephyr-7b-beta --cache-dir ./path/to/cache
232
233

# Download a specific file from a model repo
234
hf download HuggingFaceH4/zephyr-7b-beta eval_results.json
235
236
237
238
239
240
```

#### List the downloaded models

Use the Hugging Face CLI to [manage models](https://huggingface.co/docs/huggingface_hub/guides/manage-cache#scan-your-cache) stored in local cache:

241
```bash
242
# List cached models
243
hf scan-cache
244
245

# Show detailed (verbose) output
246
hf scan-cache -v
247
248

# Specify a custom cache directory
249
hf scan-cache --dir ~/.cache/huggingface/hub
250
251
252
253
254
255
```

#### Delete a cached model

Use the Hugging Face CLI to interactively [delete downloaded model](https://huggingface.co/docs/huggingface_hub/guides/manage-cache#clean-your-cache) from the cache:

#### Using a proxy

Here are some tips for loading/downloading models from Hugging Face using a proxy:

- Set the proxy globally for your session (or set it in the profile file):

```shell
export http_proxy=http://your.proxy.server:port
export https_proxy=http://your.proxy.server:port
```

- Set the proxy for just the current command:

```shell
301
https_proxy=http://your.proxy.server:port hf download <model_name>
302
303

# or use vllm cmd directly
304
https_proxy=http://your.proxy.server:port  vllm serve <model_name>
305
306
307
308
309
310
311
```

- Set the proxy in Python interpreter:

```python
import os

312
313
os.environ["http_proxy"] = "http://your.proxy.server:port"
os.environ["https_proxy"] = "http://your.proxy.server:port"
314
315
316
317
318
319
320
321
322
323
324
325
326
327
328
```

### ModelScope

To use models from [ModelScope](https://www.modelscope.cn) instead of Hugging Face Hub, set an environment variable:

```shell
export VLLM_USE_MODELSCOPE=True
```

And use with `trust_remote_code=True`.

```python
from vllm import LLM

329
llm = LLM(model=..., revision=..., runner=..., trust_remote_code=True)
330

331
# For generative models (runner=generate) only
332
333
334
output = llm.generate("Hello, my name is")
print(output)

335
# For pooling models (runner=pooling) only
336
337
338
339
340
341
342
343
344
345
346
347
348
349
350
351
output = llm.encode("Hello, my name is")
print(output)
```

## Feature Status Legend

- ✅︎ indicates that the feature is supported for the model.

- 🚧 indicates that the feature is planned but not yet supported for the model.

- ⚠️ indicates that the feature is available but may have known issues or limitations.

### Generative Models

352
See [this page](generative_models.md) for more information on how to use generative models.
353
354
355

#### Text Generation

356
357
These models primarily accept the [`LLM.generate`](./generative_models.md#llmgenerate) API. Chat/Instruct models additionally support the [`LLM.chat`](./generative_models.md#llmchat) API.

!!! note
    Grok2 requires `tokenizer.tok.json` with `tiktoken` installed. You can optionally override MoE router renormalization with `moe_router_renormalize`.

492
Some models are supported only via the [Transformers modeling backend](#transformers). The purpose of the table below is to acknowledge models which we officially support in this way. The logs will say that the Transformers modeling backend is being used, and you will see no warning that this is fallback behaviour. This means that, if you have issues with any of the models listed below, please [make an issue](https://github.com/vllm-project/vllm/issues/new/choose) and we'll do our best to fix it!

!!! note
    Currently, the ROCm version of vLLM supports Mistral and Mixtral only for context lengths up to 4096.

### Pooling Models

503
See [this page](./pooling_models.md) for more information on how to use pooling models.
504

505
!!! important
506
    Since some model architectures support both generative and pooling tasks,
507
    you should explicitly specify `--runner pooling` to ensure that the model is used in pooling mode instead of generative mode.
508

509
510
511
#### Embedding

These models primarily support the [`LLM.embed`](./pooling_models.md#llmembed) API.

534
535
536

!!! note
    `ssmits/Qwen2-7B-Instruct-embed-base` has an improperly defined Sentence Transformers config.
537
    You need to manually set mean pooling by passing `--pooler-config '{"pooling_type": "MEAN"}'`.
538
539

!!! note
540
    For `Alibaba-NLP/gte-Qwen2-*`, you need to enable `--trust-remote-code` for the correct tokenizer to be loaded.
541
542
543
    See [relevant issue on HF Transformers](https://github.com/huggingface/transformers/issues/34882).

!!! note
544
    `jinaai/jina-embeddings-v3` supports multiple tasks through LoRA, while vllm temporarily only supports text-matching tasks by merging LoRA weights.

546
547

549
550
551
552
553
554

!!! note
    The second-generation GTE model (mGTE-TRM) is named `NewModel`. The name `NewModel` is too generic, you should set `--hf-overrides '{"architectures": ["GteNewModel"]}'` to specify the use of the `GteNewModel` architecture.

If your model is not in the above list, we will try to automatically convert the model using
[as_embedding_model][vllm.model_executor.models.adapters.as_embedding_model]. By default, the embeddings
of the whole prompt are extracted from the normalized hidden state corresponding to the last token.

#### Classification

555
556

If your model is not in the above list, we will try to automatically convert the model using
567
[as_seq_cls_model][vllm.model_executor.models.adapters.as_seq_cls_model]. By default, the class probabilities are extracted from the softmaxed hidden state corresponding to the last token.

## List of Multimodal Language Models

The following modalities are supported depending on the model:

- **T**ext
- **I**mage
- **V**ideo
- **A**udio

Any combination of modalities joined by `+` are supported.

- e.g.: `T + I` means that the model supports text-only, image-only, and text-with-image inputs.

On the other hand, modalities separated by `/` are mutually exclusive.

- e.g.: `T / I` means that the model supports text-only and image-only inputs, but not text-with-image inputs.

664
See [this page](../features/multimodal_inputs.md) on how to pass multi-modal inputs to the model.
665

666
!!! tip
667
    For hybrid-only models such as Llama-4, Step3, Mistral-3 and Qwen-3.5, a text-only mode can be enabled by setting all supported multimodal modalities to 0 (`--language-model-only`) so that their multimodal modules will not be loaded to free up more GPU memory for KV cache.
668

669
!!! note
670
    vLLM currently supports adding LoRA adapters to the language backbone for most multimodal models. Additionally, vLLM now experimentally supports adding LoRA to the tower and connector modules for some multimodal models. See [this page](../features/lora.md).

### Generative Models

674
See [this page](generative_models.md) for more information on how to use generative models.
675
676
677

#### Text Generation

678
679
These models primarily accept the [`LLM.generate`](./generative_models.md#llmgenerate) API. Chat/Instruct models additionally support the [`LLM.chat`](./generative_models.md#llmchat) API.

Some models are supported only via the [Transformers modeling backend](#transformers). The purpose of the table below is to acknowledge models which we officially support in this way. The logs will say that the Transformers modeling backend is being used, and you will see no warning that this is fallback behaviour. This means that, if you have issues with any of the models listed below, please [make an issue](https://github.com/vllm-project/vllm/issues/new/choose) and we'll do our best to fix it!

!!! note
    `Gemma3nForConditionalGeneration` is only supported on V1 due to shared KV caching and it depends on `timm>=1.0.17` to make use of its
    MobileNet-v5 vision backbone.
  
    Performance is not yet fully optimized mainly due to:
  
    - Both audio and vision MM encoders use `transformers.AutoModel` implementation.  
    - There's no PLE caching or out-of-memory swapping support, as described in [Google's blog](https://developers.googleblog.com/en/introducing-gemma-3n/). These features might be too model-specific for vLLM, and swapping in particular may be better suited for constrained setups.

785
!!! note
786
    For `InternVLChatModel`, only InternVL2.5 with Qwen2.5 text backbone (`OpenGVLab/InternVL2.5-1B` etc.), InternVL3 and InternVL3.5 have video inputs support currently.

!!! note
    To use `TIGER-Lab/Mantis-8B-siglip-llama3`, you have to pass `--hf_overrides '{"architectures": ["MantisForConditionalGeneration"]}'` when running vLLM.

!!! note
    The official `openbmb/MiniCPM-V-2` doesn't work yet, so we need to use a fork (`HwwwH/MiniCPM-V-2`) for now.

## Model Support Policy

At vLLM, we are committed to facilitating the integration and support of third-party models within our ecosystem. Our approach is designed to balance the need for robustness and the practical limitations of supporting a wide range of models. Here’s how we manage third-party model support:

1. **Community-Driven Support**: We encourage community contributions for adding new models. When a user requests support for a new model, we welcome pull requests (PRs) from the community. These contributions are evaluated primarily on the sensibility of the output they generate, rather than strict consistency with existing implementations such as those in transformers. **Call for contribution:** PRs coming directly from model vendors are greatly appreciated!

2. **Best-Effort Consistency**: While we aim to maintain a level of consistency between the models implemented in vLLM and other frameworks like transformers, complete alignment is not always feasible. Factors like acceleration techniques and the use of low-precision computations can introduce discrepancies. Our commitment is to ensure that the implemented models are functional and produce sensible results.

    !!! tip
        When comparing the output of `model.generate` from Hugging Face Transformers with the output of `llm.generate` from vLLM, note that the former reads the model's generation config file (i.e., [generation_config.json](https://github.com/huggingface/transformers/blob/19dabe96362803fb0a9ae7073d03533966598b17/src/transformers/generation/utils.py#L1945)) and applies the default parameters for generation, while the latter only uses the parameters passed to the function. Ensure all sampling parameters are identical when comparing outputs.

3. **Issue Resolution and Model Updates**: Users are encouraged to report any bugs or issues they encounter with third-party models. Proposed fixes should be submitted via PRs, with a clear explanation of the problem and the rationale behind the proposed solution. If a fix for one model impacts another, we rely on the community to highlight and address these cross-model dependencies. Note: for bugfix PRs, it is good etiquette to inform the original author to seek their feedback.

4. **Monitoring and Updates**: Users interested in specific models should monitor the commit history for those models (e.g., by tracking changes in the main/vllm/model_executor/models directory). This proactive approach helps users stay informed about updates and changes that may affect the models they use.

5. **Selective Focus**: Our resources are primarily directed towards models with significant user interest and impact. Models that are less frequently used may receive less attention, and we rely on the community to play a more active role in their upkeep and improvement.

Through this approach, vLLM fosters a collaborative environment where both the core development team and the broader community contribute to the robustness and diversity of the third-party models supported in our ecosystem.

Note that, as an inference engine, vLLM does not introduce new models. Therefore, all models supported by vLLM are third-party models in this regard.

We have the following levels of testing for models:

1. **Strict Consistency**: We compare the output of the model with the output of the model in the HuggingFace Transformers library under greedy decoding. This is the most stringent test. Please refer to [models tests](https://github.com/vllm-project/vllm/blob/main/tests/models) for the models that have passed this test.
2. **Output Sensibility**: We check if the output of the model is sensible and coherent, by measuring the perplexity of the output and checking for any obvious errors. This is a less stringent test.
889
3. **Runtime Functionality**: We check if the model can be loaded and run without errors. This is the least stringent test. Please refer to [functionality tests](../../tests) and [examples](../../examples) for the models that have passed this test.
890
4. **Community Feedback**: We rely on the community to provide feedback on the models. If a model is broken or not working as expected, we encourage users to raise issues to report it or open pull requests to fix it. The rest of the models fall under this category.
