TensorRT
An NVIDIA compiler that optimizes neural networks for fast inference on NVIDIA GPUs.
Think of it like
A mechanic who fine-tunes your car engine for a specific track.
Example
Compiling a PyTorch model with TensorRT can 2-4x its inference speed with minimal accuracy loss.
How it actually works
TensorRT fuses operations (e.g., combining Conv+ReLU into one kernel), converts to lower precision (FP16, INT8), optimizes memory layout, and generates CUDA kernels. It's specific to NVIDIA hardware but offers the fastest speeds on that platform.
For product teams
TensorRT is the go-to for squeezing max throughput from NVIDIA GPUs.
For engineers
TensorRT has a learning curve and is NVIDIA-only; good if you're committed to that hardware.
