The Triton backend for TensorRT-LLM. You can learn more about Triton backends in the backend repo. The goal of TensorRT-LLM Backend is to let you serve TensorRT-LLM models with Triton Inference Server. The inflight_batcher_llm directory contains the C++ implementation of the backend supporting inflight batching, paged attention and more.
Where can I ask general questions about Triton and Triton backends? Be sure to read all the information below as well as the general Triton documentation available in the main server repo. If you don't find your answer there you can ask questions on the issues page.
There are several ways to access the TensorRT-LLM Backend.
Before Triton 23.10 release, please use Option 3 to build TensorRT-LLM backend via Docker.
Starting with Triton 23.10 release, Triton includes a container with the TensorRT-LLM Backend and Python Backend. This container should have everything to run a TensorRT-LLM model. You can find this container on the Triton NGC page.
Starting with Triton 23.10 release, you can follow steps described in the Building With Docker guide and use the build.py script.
A sample command to build a Triton Server container with all options enabled is shown below, which will build the same TRT-LLM container as the one on the NGC.
BASE_CONTAINER_IMAGE_NAME=nvcr.io/nvidia/tritonserver:23.10-py3-min
TENSORRTLLM_BACKEND_REPO_TAG=release/0.5.0
PYTHON_BACKEND_REPO_TAG=r23.10
# Run the build script. The flags for some features or endpoints can be removed if not needed.

--image=base,${BASE_CONTAINER_IMAGE_NAME} \
--backend=tensorrtllm:${TENSORRTLLM_BACKEND_REPO_TAG} \
--backend=python:${PYTHON_BACKEND_REPO_TAG}The BASE_CONTAINER_IMAGE_NAME is the base image that will be used to build the
container. By default it is set to the most recent min image of Triton, on NGC,
that matches the Triton release you are building for. You can change it to a
different image if needed by setting the --image flag like the command below.
The TENSORRTLLM_BACKEND_REPO_TAG and PYTHON_BACKEND_REPO_TAG are the tags of
the TensorRT-LLM backend and Python backend repositories that will be used
to build the container. You can also remove the features or endpoints that you
don't need by removing the corresponding flags.
The version of Triton Server used in this build option can be found in the Dockerfile.

directory that will be used in this example:
- "preprocessing": This model is used for tokenizing, meaning the conversion from prompts(string) to input_ids(list of ints).
- "tensorrt_llm": This model is a wrapper of your TensorRT-LLM model and is used for inferencing
- "postprocessing": This model is used for de-tokenizing, meaning the conversion from output_ids(list of ints) to outputs(string).
- "ensemble": This model can be used to chain the preprocessing, tensorrt_llm and postprocessing models together.
- "tensorrt_llm_bls": This model can also be used to chain the preprocessing,
tensorrt_llm and postprocessing models together. The BLS model has an optional
parameter
accumulate_tokenswhich can be used in streaming mode to call the preprocessing model with all accumulated tokens, instead of only one token. This might be necessary for certain tokenizers.
To learn more about ensemble and BLS models, please see the Ensemble Models and Business Logic Scripting sections of the Triton Inference Server documentation.

| Name | Description |
|---|---|
tokenizer_dir |
The path to the tokenizer for the model. In this example, the path should be set to /tensorrtllm_backend/tensorrt_llm/examples/gpt/gpt2 as the tensorrtllm_backend directory will be mounted to /tensorrtllm_backend within the container |
tokenizer_type |
The type of the tokenizer for the model, t5, auto and llama are supported. In this example, the type should be set to auto |
triton_model_repo/tensorrt_llm/config.pbtxt
| Name | Description |

gpt_model_type |
Mandatory. Set to inflight_fused_batching when enabling in-flight batching support. To disable in-flight batching, set to V1 |
gpt_model_path |
Mandatory. Path to the TensorRT-LLM engines for deployment. In this example, the path should be set to /tensorrtllm_backend/triton_model_repo/tensorrt_llm/1 as the tensorrtllm_backend directory will be mounted to /tensorrtllm_backend within the container |
batch_scheduler_policy |
Mandatory. Set to max_utilization to greedily pack as many requests as possible in each current in-flight batching iteration. This maximizes the throughput but may result in overheads due to request pause/resume if KV cache limits are reached during execution. Set to guaranteed_no_evict to guarantee that a started request is never paused. |

Optional (default=false). Controls streaming. Decoupled mode must be set to True if using the streaming option from the client. |
max_beam_width |
Optional (default=1). The maximum beam width that any request may ask for when using beam search. |
max_tokens_in_paged_kv_cache |
Optional (default=unspecified). The maximum size of the KV cache in number of tokens. If unspecified, value is interpreted as 'infinite'. KV cache allocation is the min of max_tokens_in_paged_kv_cache and value derived from kv_cache_free_gpu_mem_fraction below. |
max_attention_window_size |
Optional (default=max_sequence_length). When using techniques like sliding window attention, the maximum number of tokens that are attended to generate one token. Defaults attends to all tokens in sequence. |
kv_cache_free_gpu_mem_fraction |
Optional (default=0.9). Set to a number between 0 and 1 to indicate the maximum fraction of GPU memory (after loading the model) that may be used for KV cache. |
max_num_sequences |
Optional (default=max_batch_size if enable_trt_overlap is false and to 2 * max_batch_size if enable_trt_overlap is true, where max_batch_size is the TRT engine maximum batch size). Maximum number of sequences that the in-flight batching scheme can maintain state for. |
enable_trt_overlap |
Optional (default=false). Set to true to partition available requests into 2 'microbatches' that can be run concurrently to hide exposed CPU runtime |
exclude_input_in_output |
Optional (default=false). Set to true to only return completion tokens in a response. Set to false to return the prompt tokens concatenated with the generated tokens |
normalize_log_probs |
Optional (default=true). Set to false to skip normalization of output_log_probs |
triton_model_repo/postprocessing/config.pbtxt
| Name | Description |
|---|---|
tokenizer_dir |
The path to the tokenizer for the model. In this example, the path should be set to /tensorrtllm_backend/tensorrt_llm/examples/gpt/gpt2 as the tensorrtllm_backend directory will be mounted to /tensorrtllm_backend within the container |
tokenizer_type |
The type of the tokenizer for the model, t5, auto and llama are supported. In this example, the type should be set to auto |

# --world_size is the number of GPUs you want to use for serving
python3 scripts/launch_triton_server.py --world_size=4 --model_repo=/tensorrtllm_backend/triton_model_repoWhen successfully deployed, the server produces logs similar to the following ones.
I0919 14:52:10.475738 293 grpc_server.cc:2451] Started GRPCInferenceService at 0.0.0.0:8001

Starting with Triton 23.10 release, you can query the server using Triton's generate endpoint with a curl command based on the following general format within your client environment/container:
curl -X POST localhost:8000/v2/models/${MODEL_NAME}/generate -d '{"{PARAM1_KEY}": "{PARAM1_VALUE}", ... }'In the case of the models used in this example, you can replace MODEL_NAME with ensemble or tensorrt_llm_bls. Examining the
ensemble and tensorrt_llm_bls model's config.pbtxt file, you can see that 4 parameters are required to generate a response
for this model:
- "text_input": Input text to generate a response from
- "max_tokens": The number of requested output tokens
- "bad_words": A list of bad words (can be empty)
- "stop_words": A list of stop words (can be empty)
Therefore, we can query the server in the following way:
curl -X POST localhost:8000/v2/models/ensemble/generate -d '{"text_input": "What is machine learning?", "max_tokens": 20, "bad_words": "", "stop_words": ""}'if using the ensemble model or
curl -X POST localhost:8000/v2/models/tensorrt_llm_bls/generate -d '{"text_input": "What is machine learning?", "max_tokens": 20, "bad_words": "", "stop_words": ""}'
if using the tensorrt_llm_bls model.
Which should return a result similar to (formatted for readability):
{
"model_name": "ensemble",
"model_version": "1",
"sequence_end": false,
"sequence_id": 0,
"sequence_start": false,
"text_output": "What is machine learning?\n\nMachine learning is a method of learning by using machine learning algorithms to solve problems.\n\n"
}You can send requests to the "tensorrt_llm" model with the provided python client script as following:
python3 inflight_batcher_llm/client/inflight_batcher_llm_client.py --request-output-len 200 --tokenizer-dir /workspace/tensorrtllm_backend/tensorrt_llm/examples/gpt/gpt2The result should be similar to the following:

You can also stop the generation process early by using the --stop-after-ms
option to send a stop request after a few milliseconds:
python inflight_batcher_llm/client/inflight_batcher_llm_client.py --stop-after-ms 200 --request-output-len 200 --tokenizer-dir /workspace/tensorrtllm_backend/tensorrt_llm/examples/gpt/gpt2You will find that the generation process is stopped early and therefore the number of generated tokens is lower than 200. You can have a look at the client code to see how early stopping is achieved.
If you want to get context logits and/or generation logits, you need to enable --gather_context_logits and/or --gather_generation_logits when building the engine (or --enable gather_all_token_logits to enable both at the same time). For more setting details about these two flags, please refer to build.py or gpt_runtime.
After launching the server, you could get the output of logits by passing the corresponding parameters --return-context-logits and/or --return-generation-logits in the client scripts (end_to_end_grpc_client.py and inflight_batcher_llm_client.py). For example:
python3 inflight_batcher_llm/client/inflight_batcher_llm_client.py --request-output-len 20 --tokenizer-dir /path/to/tokenizer/ \

pkill tritonserverStarting with the 23.11 release of Triton, users can now obtain TRT LLM Batch Manager statistics by querying the Triton metrics endpoint. This can be accomplished by launching a Triton server in any of the ways described above (ensuring the build code / container is 23.11 or later) and querying the server. Upon receiving a successful response, you can query the metrics endpoint by entering the following:
curl localhost:8002/metricsBatch manager statistics are reported by the metrics endpoint in fields that
are prefixed with nv_trt_llm_. Your output for these fields should look
