How PhotoAIKit Is Constructed

PhotoAIKit is a reusable Swift package extracted from application code. Its most important achievement is not merely that CLIP and SAM 3 run. It is that reusable AI behavior has been separated from RawCull’s UI, RAW-file handling, paths, sandbox rules, and culling policy.

This document explains the construction from the bottom up and gives the reason for each boundary.

AI model download service

RawCull supports exactly three optional model bundles:

Model	PhotoAIKit bundle	Runtime asset	Use
DataComp CLIP	`CLIP-DataComp`	`ViT-B-32-256-datacomp_s34b_b86k_float16_static.aimodel`	Similarity and semantic search
OpenAI CLIP	`CLIP-OpenAI`	`clip-vit-base-patch32_float16_static.aimodel`	Similarity and semantic search
Meta SAM 3	`SAM3`	`sam3_float16.aimodel`	Promptable segmentation

SigLIP2 and EfficientSAM are not part of the RawCull download catalogue or release manifest. Do not include their bundles, notices, archives, or asset-pack IDs in a RawCull model release.

Evaluating CLIP Models

Evaluating CLIP Models Against Source-Framework Cosine Values and RawCullFB

This document is the complete repeatable procedure for validating CLIP model bundles used by RawCullFB. It covers both supported candidates:

OpenAI CLIP ViT-B/32 at 224 × 224.
OpenCLIP DataComp ViT-B/32-256 with datacomp_s34b_b86k weights.

SigLIP2 is outside the current evaluation scope.

The procedure has two independent validation layers:

Numerical parity: compare embeddings produced by the Core AI bundle with reference embeddings produced by the original Hugging Face Transformers or OpenCLIP implementation.
Product behavior: use RawCullFB to build a real catalog index, execute the same 77 semantic queries, inspect image-similarity neighborhoods, and measure labeled retrieval quality.

A model must pass both layers. Numerical parity proves that the conversion and integration reproduce the source model; it does not prove that the model retrieves useful photographs. Conversely, plausible search results do not prove that the converted model is correct.

New RawCull AI models

Publishing new RawCull AI models

This runbook publishes exactly three optional models:

Model	Asset-pack ID	Installed destination
DataComp CLIP	`no.blogspot.RawCull.models.clip-datacomp`	`Models/CLIP-DataComp`
OpenAI CLIP	`no.blogspot.RawCull.models.clip-openai`	`Models/CLIP-OpenAI`
Meta SAM 3	`no.blogspot.RawCull.models.sam3`	`Models/SAM3`

SigLIP2 and EfficientSAM are deliberately excluded. Do not add them to the release staging tree, packaging manifests, download manifest, production catalogue, settings UI, notices, or tests.

The examples use the v2 release in RawCull-AI-Models. Tag names and GitHub release URLs are case-sensitive. If another tag is chosen, replace v2 everywhere and keep both RawCull manifest URLs identical.

Artificial Intelligence in RawCull

This section explains how RawCull uses reusable AI components without allowing model-runtime details to spread through the application. It is written as a learning path: first understand the boundary between RawCull and PhotoAIKit, then study the package itself, and finally follow CLIP from application startup to a persisted similarity artifact.

The source for this section comes from the sibling PhotoAIKit and RawCull projects. Paths beginning with Sources/ refer to PhotoAIKit. Paths beginning with Model/, Main/, Views/, or Actors/ refer to the RawCull app target.
