ScaleDown

ScaleDown Classify-1 is a structured decision model served through OpenRouter's Decisions API. It scores text or a document against caller-defined choice, yes/no, and ordered-scale questions and returns calibrated probabilities rather than generated prose, making it suited for routing, moderation, intent detection, and domain tagging inside an application. Call POST /api/v1/decisions (POST /api/v1/systemone is the same handler).

ScaleDown Extract is a description-driven entity extraction model. Instead of a fixed set of entity types, callers describe the fields they want in plain English through provider.options.scaledown.entities, and the model returns each matching span with a confidence score, character offsets, and surrounding context. It is suited for pulling structured values out of contracts, invoices, emails, and transcripts, and includes built-in OCR so scanned images and PDFs work without a separate step.

ScaleDown Summarize is an abstractive summarization model that condenses long text and documents into a fluent, faithful rewrite rather than lifting sentences from the source. It is suited for document review, transcript digests, and RAG pre-processing where retrieved content must be shortened before reaching another model. Format, focus, language, and length are steered through the system prompt, while sampling is fixed to a configuration tuned for faithful output.
