Fit notes	Good fit: classification, routing, prioritization, and review queues with app-owned thresholds set from your own labeled examples. Only the alias gpt-6-luna is documented — behavior can change under you. Run a canary eval and log the model string on every call. No rationale is returned; if users need an explanation, pair it with a generative model and human review. OpenAI Usage Policies restrict automating high-stakes decisions in sensitive areas (e.g. critical infrastructure, product safety components, medical) without human review. Keep it advisory; never the sole authority.	Cheapest per-token hosted option here (Clef-flash) but with the smallest context; long text state is truncated to fit. Test calibration and order sensitivity on your own labels; vendor pages publish no accuracy figure.
