# Superseded checkpoint — do not use

This is an **old development checkpoint**, kept only so that earlier results
remain reproducible. It is not the current detector, it is not what any TextSight
product runs, and its behaviour has not been measured on any current benchmark.

**Use [`textsightai/textsight-detector-v23-custom`](https://huggingface.co/textsightai/textsight-detector-v23-custom)
instead.** That card documents measured performance, per-domain false-positive
rates, how to score correctly (log-odds, not softmax), and where the model fails.

## If you are benchmarking AI detectors

Please do not report numbers from this checkpoint as representing TextSight. It
predates the current model and carries none of the input handling a deployed
detector needs. Reproducible measurement code for the current model is at
[textsight/textsight-detector-benchmark](https://github.com/textsight/textsight-detector-benchmark).
