# CLIP_VITB32_512

CLIP_VITB32_512 is a light image embedding model for fast visual grouping in EIDORA. Choose it when you want a broadly useful visual model that runs on most laptops.

## Best For

- Fast first-pass visual grouping.
- Image collections where semantic similarity matters more than exact object classification.
- A broadly useful starter model for EIDORA image workflows.

## Not Ideal For

- Fine-grained visual similarity where a heavier model is acceptable.
- Text-only projects.
- Specialized domains that need a domain-trained visual encoder.

## Compute Tier

Light: small download, low memory, faster CPU runtime. Intended for laptop CPU use and large first-pass projects.

## Inputs

- `image`: required image input from `media_source`.

## Output

The primary output is `embedding`, a float32 tensor shaped `[batch, 512]`. Embeddings are already normalized and are intended for cosine similarity.

## Usage In EIDORA

EIDORA shows this package as a light image embedding model in the Model Zoo. Use it for discovery maps, grouping, retrieval, and related embedding workflows.

## Preprocessing

- `image`: resize mode defaults to `crop_center`; rescale uses `1/255`; normalize inside the ONNX graph with mean `[0.48145466, 0.4578275, 0.40821073]` and std `[0.26862954, 0.26130258, 0.27577711]`.

## Authorship And Citation

This ONNX package was produced by EIDORA from the original CLIP ViT-B/32 model. EIDORA converted the model to ONNX and is not the original model creator.

## Training Data And Provenance

Base model: `openai/clip-vit-base-patch32`. Source repository: https://huggingface.co/openai/clip-vit-base-patch32. Known training data: WebImageText-style image/text pairs described by the upstream CLIP authors. Package payload size: 351584808 bytes.

## Evaluation And Validation

The package validation checks that the ONNX graph loads with ONNX Runtime CPU execution, runs the declared fixtures, returns finite float32 embeddings with the declared shape, and matches the artifact hash recorded in `config.yaml`.

## Limitations And Safety

CLIP embeddings can reflect web-scale training data biases and may miss fine visual details. Similarity scores should not be used as sole evidence for identity, authorship, intent, or sensitive attributes.

## License And Attribution

This package uses license `mit`. Upstream license: MIT. Converted to ONNX for EIDORA from the original OpenAI CLIP model.

## Version

Package version: 1.0.0. ONNX opset: 17. Exporter: eidora-onnx-exporter 0.1.0.
