📄 中文摘要
PromptLab 是一个 Python 命令行工具，旨在帮助开发者系统性地测试和比较大语言模型（LLM）的提示。用户通常会经历编写提示、在 ChatGPT 中手动测试、调整提示、将其复制粘贴到代码中，以及在生产环境中发现效果不佳的循环。PromptLab 通过允许用户定义带有模板变量的提示，简化了这一过程。用户可以直接在终端中输入提示，指定变量和模型，从而高效地进行多种提示的测试和比较。

PromptLab: Test and Compare LLM Prompts From Your Terminal (Open Source)
PromptLab is a Python CLI tool designed to help developers systematically test and compare prompts for large language models (LLMs). Users often go through a cycle of writing prompts, manually testing them in ChatGPT, tweaking them, copying and pasting into code, and realizing they do not work as well in production. PromptLab simplifies this process by allowing users to define prompts with template variables. Users can directly input prompts in the terminal, specify variables and models, enabling efficient testing and comparison of multiple prompt variations.
