- NVIDIA releases TensorRT Model Connect (TRTMC) in public preview for evaluation and native integration.
- Enables direct conversion from Hugging Face checkpoints to native C++ inference in two simple commands.
- Cleanly separates build and runtime artifacts, eliminating PyTorch dependency during execution.
- Current release wheels target Linux aarch64 with Python 3.10 or 3.12 and TensorRT 11.1.0.106.
NVIDIA has introduced a significant advancement for artificial intelligence deployment with the public preview release of TensorRT Model Connect (TRTMC). Designed to streamline evaluation and native integration work under real-world conditions, the open and installable codebase aims to bridge the gap between model training checkpoints and production environments.
The release wheels currently target Linux aarch64 systems specifically, requiring Python 3.10 or 3.12, glibc 2.39 or newer, and TensorRT 11.1.0.106. Developers utilizing x86_64 architecture are required to follow the Docker source-build path for deployment.
The quick start workflow demonstrates building and executing the Qwen3-0.6B model through streamlined CLI instructions:
- Building the bundle:
trtmc build Qwen/Qwen3-0.6B --precision bf16 --max-cache-length 16384 --output qwen3-0.6b.bundle - Running the bundle:
trtmc run ./qwen3-0.6b.bundle --prompt "What is the capital of France? Answer in one word." --chat-template --no-thinking
Furthermore, the exact same generated bundle can be loaded seamlessly from C++ applications using the command trtmc::load("./qwen3-0.6b.bundle").
The introduction of TensorRT Model Connect highlights NVIDIA's focus on solving long-standing deployment bottlenecks in machine learning engineering. Traditional pipelines often required complex conversion chains—moving from PyTorch to ONNX or TorchScript, then to TensorRT, followed by custom C++ integration glue for every individual model. By decoupling the runtime from PyTorch and establishing a versioned artifact format, TRTMC significantly reduces operational overhead and integration friction for production systems.
TRTMC divides the build and runtime processes at a versioned artifact boundary. Python handles checkpoint resolution and TensorRT engine construction, while native profiles execute inference directly in C++ without requiring PyTorch at runtime. A small subset of hybrid profiles may invoke a helper Python executable, with their specific dependencies explicitly declared in their manifests.

Instead of maintaining complex conversion stages and custom model application glue, application developers can rely on standard task APIs such as generate(), transcribe(), generate_image(), embed(), and solve(). Additionally, the trtmc inspect utility exposes critical metadata including bundle kind, model family, precision, runtime identity, and underlying engines, rendering the artifact fully auditable rather than opaque.
NVIDIA contrasts this streamlined approach with the conventional route—PyTorch to ONNX or TorchScript to TensorRT, followed by model-specific C++ integration—explicitly removing known failure modes such as export gaps, redundant per-model integration work, and validation efforts scattered across multiple intermediate conversion artifacts.
