An Apple Core AI conversion of feyninc/pulpie-orange-base — a token classifier (bidirectional encoder) that maps (input_ids, attention_mask) to per-token logits. Produced by coreai-fabric and indexed by coreai-catalog.

Encoder, not a chat model. This is a single-forward classifier — no text generation, no KV-cache. The host owns the tokenizer (use the upstream tokenizer at feyninc/pulpie-orange-base), feeds token ids, and reads the per-token argmax.

Use it — this needs host code you supply

The bundle is a single static-sequence graph: (input_ids, attention_mask) in → per-token logits out. You supply the upstream tokenizer and the argmax / label mapping in your host code (Swift or Python). Token ids are int32 at the graph boundary; pad or truncate to the static sequence length (see Model facts).

pip install coreai-catalog && coreai-catalog install pulpie-orange-base

Requirements

Deployment: macOS 27.0+ / iOS 27.0+, Xcode 27+. The asset serializes with minimum_os v27, so the on-device Swift runtime requires macOS/iOS 27+. A Mac on macOS 26 can convert and inspect it but not run it on-device.
Apple Silicon.

Verification (output parity)

Gate A (structure): passed — the bundle's layout + metadata were validated; the graph loads.
Gate B — graph_output_cosine: 1.000000 min output cosine (median 1.000000) vs the fp32 torch reference over 8 seeded (input_ids, attention_mask), measured on apple_silicon. The encoder analog of the LLM logit-parity: it certifies the export computes the SAME per-token logits as the source — a conversion-fidelity metric, not task accuracy.
This certifies the export is numerically faithful to the source encoder — it does NOT certify downstream task accuracy on your data. Reproduce with coreai-fabric verify.
