Abstention Python Packages

ir

An information-retrieval substrate for agentic systems

recall-rag

Memory that abstains instead of guessing: agent memory on your own Postgres with a verdict, confidence and provenance on every hit, and a calibrated refusal when nothing clears the threshold.

abstention

Algorithms for abstention, calibration and domain adaptation to label shift.

quaesitor-zero

A tiny, offline check for abstention in text-to-SQL and RAG-over-warehouse assistants: does it say it cannot answer instead of returning a confident wrong number? No model access, no network.

masstrust

Calibrated trust and abstention for MS/MS molecular annotations

cairn-pipeline

A retrieval pipeline that answers from your documents, cites the exact span it used, and abstains with a calibrated guarantee when the evidence is thin. A promotion gate refuses any change that makes it worse. Every number reproduces with no API key.

abstain-bench

How often does your verifier claim success on input it could not check? A benchmark for unearned passes
