# SAM3 TensorRT Engine

<!-- fury-evidence-20260930:start -->
## Results and visual examples

Hardware-specific SAM3 TensorRT artifacts and runtime metadata. Prompted masks from another SAM3 runtime are not proof for these exact engines. Validate the engine revision, GPU architecture, TensorRT version and metadata together before use.

No checkpoint-matched photo gallery was located in the existing evidence reviewed for this update. The files and runtime records below are the available evidence; no visual quality claim is inferred from their presence.

### Evidence provenance

This documentation update reuses saved results; it does not rerun inference or change weights. The starting repository revision is [`7787e2951766`](https://huggingface.co/carpedm20/sam3-tensorrt/tree/7787e29517660658923d3384685b57bd038e010a). Captions distinguish model predictions, training diagnostics, and aggregate metrics. Qualitative examples are not a representative accuracy estimate.
