Emberdyn Editorial V1 — ModernBERT (Core ML)

The runtime resource for Emberdyn Editorial Intelligence V1, used on-device by EmberdynAI inside CutScript. This repository exists so the model can be downloaded on demand rather than embedded in an application bundle.

This is not a general-purpose model. It is a packaged runtime artifact: a Core ML conversion of ModernBERT-base, the upstream tokenizer, and an Emberdyn-trained classification head, with digests so a truncated or substituted download is rejected rather than silently producing different editorial output.

Base model

answerdotai/ModernBERT-base, revision 8949b909ec900327062f0ebf497f51aef5e6f0c8.

What Emberdyn changed

1. Core ML conversion. The upstream distribution has no Core ML artifact; the weights were converted for on-device Apple inference. Architecture and learned parameters are unchanged by that step — it is a format conversion, not a retrain or a quantisation.
2. A trained head. v1_head.bin is Emberdyn's own work. It consumes ModernBERT embeddings at runtime and contains no upstream parameters.

Answer.AI did not create, review or endorse Emberdyn Editorial V1. The base model is theirs; the conversion, the head and the editorial behaviour are Emberdyn's.
