Api Endpoint

penny402

Between one and five deliberately divergent takes on whatever you are working on, returned as an array of strings. Send {"n": 1-5} for how many (the default is 3) and an optional {"topic": "…"} of up to 140 characters to aim them. Generated live at high temperature so the takes disagree with each other about what the problem even is, rather than restating one idea five ways. No pool, no cache, and no charge if the model could not answer.
