Vendors can pay for top positions in our rankings and for a place on other products' pages, and we may earn a commission when you click some links. Bought places stand at the number bought; this page and our disclosure say so. Paying vendors may get a fuller, more detailed review from our editors, and that review can change their score.

Our review
Pros
  • Compiles models into hardware-specific inference engines
  • Supports FP8, FP4, INT8, and INT4 quantization
  • Provides multi-GPU inference with C++ and Python APIs
  • CompiledModel supports CPU, GPU, and NPU inference
  • Quantization options include dynamic-range, integer, and float16
  • LiteRT.js enables browser inference with WebAssembly and WebGPU/WebNN
Cons
  • Requires NVIDIA GPUs, limiting portability across accelerator vendors
  • Inference-focused; it does not provide a general model-training workflow
  • Developer access centers on C++ and Python APIs
  • Requires model conversion and deployment work rather than offering hosted inference
  • Legacy Interpreter and CompiledModel APIs may complicate runtime choices
  • Support channels are documentation and community
