mlpeek: rerank documents against a query

rerank_documents

Read-onlyIdempotent

mlpeek: Rerank up to 100 documents against a query. Returns 1-100 documents scored against a query by the ms-marco-MiniLM-L6-v2 cross-encoder (Apache-2.0) and sorted best first: index, rank, score (sigmoid of the logit, a relevance in 0-1) and logit; top_k keeps the best k. English model. Input: query, documents, optional top_k. Each text is cut at the model's 512-token window and the answer says so (longest side first). Over 32,768 tokens per request is a 422 too_many_tokens (not charged). Runs an open model pinned by hash on Tanod's own CPU (no LLM, no third-party API); an unavailable model is a 503 (not charged). Typically 0.1-2 s, up to about 10 s at the token budget. Price: USD 0.002. Free: 5 mlpeek calls per IP per UTC day. Tanod does not log or store the submitted text; it is processed in memory for this answer.
