TensorRT LLM Overview
TensorRT LLM is an open-sourced library for optimizing LLM and Visual Gen inference. It provides state-of-the-art optimizations, including custom kernels for common inference operations (attention, GEMMs, MoE, ...), algorithmic runtime optimizations (Prefill-Decode disaggregation, Wide Expert Parallelism, Speculative Decoding, etc), and much more, to perform inference efficiently on NVIDIA GPUs.
Architected on PyTorch, TensorRT LLM provides a high-level Python LLM API that supports a wide range of inference setups - from single-GPU to multi-GPU or multi-node deployments. It includes built-in support for various parallelism strategies and advanced features. The LLM API integrates seamlessly with the broader inference ecosystem, including NVIDIA Dynamo and the Triton Inference Server.
TensorRT LLM is designed to be modular and easy to modify. Its PyTorch-native architecture allows developers to experiment with the runtime or extend functionality. Several popular models are also pre-defined and can be customized using native PyTorch code, making it easy to adapt the system to specific needs.
Getting Started
To get started with TensorRT-LLM, visit our documentation:
- Quick Start Guide
- Running DeepSeek
- Installation Guide
- Supported Hardware, Models, and other Software
- Benchmarking Performance
- Release Notes
Deprecation Policy
Deprecation is used to inform developers that some APIs and tools are no longer recommended for use. Beginning with version 1.0, TensorRT LLM has the following deprecation policy:
- Communication of Deprecation
- Deprecation notices are documented in the Release Notes.
- Deprecated APIs, methods, classes, or parameters include a statement in the source code indicating when they were deprecated.
- If used, deprecated methods, classes, or parameters issue runtime deprecation warnings.
- Migration Period
- TensorRT LLM provides a 3-month migration period after deprecation.
- During this period, deprecated APIs, tools, or parameters continue to work but trigger warnings.
- Scope of Deprecation
- Full API/Method/Class Deprecation: The entire API/method/class is marked for removal.
- Partial Deprecation: If only specific parameters of an API/method are deprecated (e.g., param1 in LLM.generate(param1, param2)), the method itself remains functional, but the deprecated parameters will be removed in a future release.
- Removal After Migration Period
- After the 3-month migration period ends, deprecated APIs, tools, or parameters are removed in a manner consistent with semantic versioning (major version changes may include breaking removals).
Telemetry Data Collection
TensorRT-LLM collects anonymous telemetry data by default. This data is used in aggregate to understand usage patterns and prioritize engineering efforts. This data cannot be traced back to any individual user. No prompts, outputs, model weights, model paths, tokenizer paths, user-identifying information, raw free-form configuration strings, or persistent identifiers are collected. Any deployment identifiers are ephemeral, randomly generated per deployment, and not linked to users. The data we collect includes:
- Ingress point (e.g., LLM API, CLI, serve command)
- Deployment duration (via periodic heartbeats)
- GPU SKUs, count, memory, and CUDA version
- Model architecture class name (e.g.,
LlamaForCausalLM) - Parallelism configuration (TP/PP/CP/MoE-EP/MoE-TP sizes), quantization algorithm, dtype, KV cache dtype
- System information (OS platform, Python version, CPU architecture, CPU count)
- TRT-LLM version and backend
- Feature summary flags (LoRA, speculative decoding, prefix caching, CUDA graphs, chunked context, data parallelism)
- Disaggregated serving metadata (role and deployment ID)
- Selected LLM API configuration values: parallelism, dtype, KV cache, scheduler, CUDA graph, and compile settings
- Capture diagnostics for that payload: a schema checksum (for provenance), the count of captured fields, and whether any free-form value was skipped
Telemetry is automatically disabled in CI and test environments.
Opting Out of Telemetry Data Collection
To disable telemetry data collection, use any of the following methods:
- Environment variable: Set
TRTLLM_NO_USAGE_STATS=1,DO_NOT_TRACK=1, orTELEMETRY_DISABLED=true - File-based: Create the file
~/.config/trtllm/do_not_track - Python API: Pass
TelemetryConfig(disabled=True)toLLM() - CLI flag: Use
--no-telemetryontrtllm-serve,trtllm-bench, ortrtllm-eval
The telemetry collection code is fully open source and auditable at
tensorrt_llm/usage/. For a detailed field-by-field
reference of exactly what is collected, see the
schema documentation.
