Perpend 曾是什么产品？（历史档案）
Perpend was a lightweight developer utility and web-based UI wrapper designed for prototyping and experimenting with OpenAI's GPT models. Instead of manually writing API test scripts or wrestling with raw JSON payloads, developers and prompt engineers could use its clean interface to tweak hyperparameters, test dynamic prompts, and instantly inspect model outputs.
