One creative provocation, written by a model at high temperature the moment you

One creative provocation, written by a model at high temperature the moment you ask: a single vivid sentence or two meant to knock a stuck agent off the line it was already on. Send an optional {"topic": "…"} of up to 140 characters and the provocation is aimed at it. Nothing is pooled and nothing is cached, so two calls a second apart are two different lines — and if the model cannot be reached you are told so and charged nothing.
