anylearning-sam3-onnx
nrl-ai/anylearning-sam3-onnx
anylearning-sam3-onnx is a image segmentation model from nrl-ai. Use it for the image segmentation task on the model card, and read the license before you ship it in a product. It is set up for onnx. The card lists the license as other.
This repository contains an ONNX conversion of Meta's SAM3 ViT-H model for text, point, box, and combined-prompt segmentation in AnyLearning inference and its authenticated server.

SAM3 ViT-H ONNX graph triplet for AnyLearning
This repository contains an ONNX conversion of Meta's SAM3 ViT-H model for text, point, box, and combined-prompt segmentation in AnyLearning inference and its authenticated server.
License
The model weights and converted ONNX artifacts remain subject to Meta's SAM License, not Apache-2.0. Read LICENSE before downloading, using, or redistributing the model. The exporter/runtime wrapper used for the conversion is MIT-licensed; that code license does not relicense the weights.

MANIFEST.json records every archive member's exact byte size and SHA-256.
AnyLearning verifies the three graph files and every referenced external tensor
file independently before creating ONNX Runtime sessions.
Graph contract
| Role | Input | Outputs |
|---|---|---|
| Image encoder | RGB uint8 CHW [3,1008,1008] | six FPN/position feature maps |
| Language encoder | CLIP tokens int64 [1,32] | attention mask, memory, embeddings |
| Decoder | image/language features and one fixed geometric slot | boxes, scores, native-size masks |
The decoder graph in this bundle emits processed boxes, scores, and masks. Its
historical .data companion is present in the original archive but is not
referenced by the decoder graph; AnyLearning does not load it.
Safe download and extraction
Treat model archives as untrusted data. Verify the archive digest, require the
exact members and sizes from MANIFEST.json, reject links and unexpected paths,
and extract each approved member to an explicit destination. Avoid generic
archive extraction calls.
The graph triplet is several gigabytes. Keep downloads resumable, enforce disk and memory quotas, and use AnyLearning's digest-addressed external-data loader instead of reading all tensor files into Python memory.
Validation
The pinned bundle is tested with real images through both in-process inference and the password-authenticated HTTP server. Retained reports cover text, text-plus-point, and box prompts, deterministic repeated results, load/unload cycles, stage timings, peak RSS, editable polygons, and visual inspection.
