Engine Arguments

Engine Arguments#

Engine arguments control the behavior of the vLLM engine.

For offline inference, they are part of the arguments to LLM class.
For online serving, they are part of the arguments to vllm serve.

Below, you can find an explanation of every engine argument:

Default: “auto”

--max-model-len

Model context length. If unspecified, will be automatically derived from the model config.

--guided-decoding-backend

Which engine will be used for guided decoding (JSON schema / regex etc) by default. Currently support mlc-ai/xgrammar and guidance-ai/llguidance.Valid backend values are “xgrammar”, “guidance”, and “auto”. With “auto”, we will make opinionated choices based on requestcontents and what the backend libraries currently support, so the behavior is subject to change in each release.

Default: “xgrammar”

--logits-processor-pattern

Optional regex pattern specifying valid logits processor qualified names that can be passed with the logits_processors extra completion argument. Defaults to None, which allows no processors.

--model-impl

“transformers” will use the Transformers model implementation.

Default: “auto”

--distributed-executor-backend

Possible choices: ray, mp, uni, external_launcher

Backend to use for distributed model workers, either “ray” or “mp” (multiprocessing). If the product of pipeline_parallel_size and tensor_parallel_size is less than or equal to the number of GPUs available, “mp” will be used to keep processing on a single host. Otherwise, this will default to “ray” if Ray is installed and fail otherwise. Note that tpu only supports Ray for distributed inference.

--pipeline-parallel-size, -pp

Number of pipeline stages.

Default: 1

--tensor-parallel-size, -tp

Number of tensor parallel replicas.

Default: 1

--data-parallel-size, -dp

Number of data parallel replicas. MoE layers will be sharded according to the product of the tensor-parallel-size and data-parallel-size.

Default: 1

--enable-expert-parallel

Use expert parallelism instead of tensor parallelism for MoE layers.

--max-parallel-loading-workers

Load model sequentially in multiple batches, to avoid RAM OOM when using tensor parallel and large models.

--ray-workers-use-nsight

If specified, use nsight to profile Ray workers.

--block-size

Possible choices: 8, 16, 32, 64, 128

Token block size for contiguous chunks of tokens. This is ignored on neuron devices and set to --max-model-len. On CUDA devices, only block sizes up to 32 are supported. On HPU devices, block size defaults to 128.

--enable-prefix-caching, --no-enable-prefix-caching

Enables automatic prefix caching. Use --no-enable-prefix-caching to disable explicitly.

--prefix-caching-hash-algo

Possible choices: builtin, sha256

Set the hash algorithm for prefix caching. Options are ‘builtin’ (Python’s built-in hash) or ‘sha256’ (collision resistant but with certain overheads).

Default: “builtin”

--disable-sliding-window

Disables sliding window, capping to sliding window size.

--use-v2-block-manager

[DEPRECATED] block manager v1 has been removed and SelfAttnBlockSpaceManager (i.e. block manager v2) is now the default. Setting this flag to True or False has no effect on vLLM behavior.

--num-lookahead-slots

Experimental scheduling config necessary for speculative decoding. This will be replaced by speculative config in the future; it is present to enable correctness tests until then.

Default: 0

--seed

Random seed for operations.

--swap-space

CPU swap space size (GiB) per GPU.

Default: 4

--cpu-offload-gb

The space in GiB to offload to CPU, per GPU. Default is 0, which means no offloading. Intuitively, this argument can be seen as a virtual way to increase the GPU memory size. For example, if you have one 24 GB GPU and set this to 10, virtually you can think of it as a 34 GB GPU. Then you can load a 13B model with BF16 weight, which requires at least 26GB GPU memory. Note that this requires fast CPU-GPU interconnect, as part of the model is loaded from CPU memory to GPU memory on the fly in each model forward pass.

Default: 0

--gpu-memory-utilization

The fraction of GPU memory to be used for the model executor, which can range from 0 to 1. For example, a value of 0.5 would imply 50% GPU memory utilization. If unspecified, will use the default value of 0.9. This is a per-instance limit, and only applies to the current vLLM instance.It does not matter if you have another vLLM instance running on the same GPU. For example, if you have two vLLM instances running on the same GPU, you can set the GPU memory utilization to 0.5 for each instance.

Default: 0.9

--num-gpu-blocks-override

If specified, ignore GPU profiling result and use this number of GPU blocks. Used for testing preemption.

--max-num-batched-tokens

For chunked prefill, the max number of concurrent partial prefills.

Default: 1

--max-long-partial-prefills

For chunked prefill, the maximum number of prompts longer than –long-prefill-token-threshold that will be prefilled concurrently. Setting this less than –max-num-partial-prefills will allow shorter prompts to jump the queue in front of longer prompts in some cases, improving latency.

Default: 1

--long-prefill-token-threshold

For chunked prefill, a request is considered long if the prompt is longer than this number of tokens.

Default: 0

--max-num-seqs

Maximum number of sequences per iteration.

--max-logprobs

Max number of log probs to return logprobs is specified in SamplingParams.

Default: 20

--disable-log-stats

Disable logging statistics.

Method used to quantize the weights. If None, we first check the quantization_config attribute in the model config file. If that is None, we assume the model weights are not quantized and use dtype to determine the data type of the weights.

--rope-scaling

RoPE scaling configuration in JSON format. For example, {"rope_type":"dynamic","factor":2.0}

--rope-theta

RoPE theta. Use with rope_scaling. In some cases, changing the RoPE theta improves the performance of the scaled model.

--hf-overrides

Extra arguments for the HuggingFace config. This should be a JSON string that will be parsed into a dictionary.

--enforce-eager

Always use eager-mode PyTorch. If False, will use eager mode and CUDA graph in hybrid for maximal performance and flexibility.

--max-seq-len-to-capture

Maximum sequence length covered by CUDA graphs. When a sequence has context length larger than this, we fall back to eager mode. Additionally for encoder-decoder models, if the sequence length of the encoder input is larger than this, we fall back to the eager mode.

Default: 8192

--disable-custom-all-reduce

See ParallelConfig.

--tokenizer-pool-size

Size of tokenizer pool to use for asynchronous tokenization. If 0, will use synchronous tokenization.

Default: 0

--tokenizer-pool-type

Type of tokenizer pool to use for asynchronous tokenization. Ignored if tokenizer_pool_size is 0.

Default: “ray”

--tokenizer-pool-extra-config

Extra config for tokenizer pool. This should be a JSON string that will be parsed into a dictionary. Ignored if tokenizer_pool_size is 0.

--limit-mm-per-prompt

For each multimodal plugin, limit how many input instances to allow for each prompt. Expects a comma-separated list of items, e.g.: image=16,video=2 allows a maximum of 16 images and 2 videos per prompt. Defaults to 1 for each modality.

--mm-processor-kwargs

Overrides for the multimodal input mapping/processing, e.g., image processor. For example: {"num_crops": 4}.

--disable-mm-preprocessor-cache

If true, then disables caching of the multi-modal preprocessor/mapper. (not recommended)

Default: “auto”

--long-lora-scaling-factors

Specify multiple scaling factors (which can be different from base model scaling factor - see eg. Long LoRA) to allow for multiple LoRA adapters trained with those scaling factors to be used at the same time. If not specified, only adapters trained with the base model scaling factor are allowed.

--max-cpu-loras

Maximum number of LoRAs to store in CPU memory. Must be >= than max_loras.

--fully-sharded-loras

By default, only half of the LoRA computation is sharded with tensor parallelism. Enabling this will use the fully sharded layers. At high sequence length, max rank or tensor parallel size, this is likely faster.

--enable-prompt-adapter

If True, enable handling of PromptAdapters.

--max-prompt-adapters

Max number of PromptAdapters in a batch.

Default: 1

--ignore-patterns

The pattern(s) to ignore when loading the model.Default to original/**/* to avoid repeated loading of llama’s checkpoints.

Default: []

--preemption-mode

If ‘recompute’, the engine performs preemption by recomputing; If ‘swap’, the engine performs preemption by block swapping.

--served-model-name

The model name(s) used in the API. If multiple names are provided, the server will respond to any of the provided names. The model name in the model field of a response will be the first name in this list. If not specified, the model name will be the same as the --model argument. Noted that this name(s) will also be used in model_name tag content of prometheus metrics, if multiple names provided, metrics tag will take the first one.

--qlora-adapter-name-or-path

Name or path of the QLoRA adapter.

--show-hidden-metrics-for-version

Enable deprecated Prometheus metrics that have been hidden since the specified version. For example, if a previously deprecated metric has been hidden since the v0.7.0 release, you use –show-hidden-metrics-for-version=0.7 as a temporary escape hatch while you migrate to new metrics. The metric is likely to be removed completely in an upcoming release.

--otlp-traces-endpoint

Target URL to which OpenTelemetry traces will be sent.

--collect-detailed-traces

Valid choices are model,worker,all. It makes sense to set this only if --otlp-traces-endpoint is set. If set, it will collect detailed traces for the specified modules. This involves use of possibly costly and or blocking operations and hence might have a performance impact.

--disable-async-output-proc

Disable async output processing. This may result in lower performance.

--scheduling-policy

Possible choices: fcfs, priority

The scheduling policy to use. “fcfs” (first come first served, i.e. requests are handled in order of arrival; default) or “priority” (requests are handled based on given priority (lower value means earlier handling) and time of arrival deciding any ties).

Default: “fcfs”

--scheduler-cls

The scheduler class to use. “vllm.core.scheduler.Scheduler” is the default scheduler. Can be a class directly or the path to a class of form “mod.custom_class”.

--override-neuron-config

Override or set neuron device configuration. e.g. {"cast_logits_dtype": "bloat16"}.

--override-pooler-config

Override or set the pooling method for pooling models. e.g. {"pooling_type": "mean", "normalize": false}.

--compilation-config, -O

torch.compile configuration for the model.When it is a number (0, 1, 2, 3), it will be interpreted as the optimization level. NOTE: level 0 is the default level without any optimization. level 1 and 2 are for internal testing only. level 3 is the recommended level for production. To specify the full compilation config, use a JSON string. Following the convention of traditional compilers, using -O without space is also supported. -O3 is equivalent to -O 3.

--kv-transfer-config

The configurations for distributed KV cache transfer. Should be a JSON string.

--worker-cls

The worker class to use for distributed execution.

Default: “auto”

--worker-extension-cls

Default: “”

--generation-config

The folder path to the generation config. Defaults to ‘auto’, the generation config will be loaded from model path. If set to ‘vllm’, no generation config is loaded, vLLM defaults will be used. If set to a folder path, the generation config will be loaded from the specified folder path. If max_new_tokens is specified in generation config, then it sets a server-wide limit on the number of output tokens for all requests.

Default: auto

--override-generation-config

Overrides or sets generation config in JSON format. e.g. {"temperature": 0.5}. If used with –generation-config=auto, the override parameters will be merged with the default config from the model. If generation-config is None, only the override parameters are used.

--enable-sleep-mode

Enable sleep mode for the engine. (only cuda platform is supported)

--calculate-kv-scales

This enables dynamic calculation of k_scale and v_scale when kv-cache-dtype is fp8. If calculate-kv-scales is false, the scales will be loaded from the model checkpoint if available. Otherwise, the scales will default to 1.0.

--additional-config

Additional config for specified platform in JSON format. Different platforms may support different configs. Make sure the configs are valid for the platform you are using. The input format is like ‘{“config_key”:”config_value”}’

--enable-reasoning

Whether to enable reasoning_content for the model. If enabled, the model will be able to generate reasoning content.

--reasoning-parser

Possible choices: deepseek_r1, granite

Select the reasoning parser depending on the model that you’re using. This is used to parse the reasoning content into OpenAI API format. Required for --enable-reasoning.

--disable-cascade-attn

Disable cascade attention for V1. While cascade attention does not change the mathematical correctness, disabling it could be useful for preventing potential numerical issues. Note that even if this is set to False, cascade attention will be only used when the heuristic tells that it’s beneficial.
