原文翻译： 本文提供了一份精选的大型语言模型（LLM）应用构建工具和产品清单，包括开发框架、实验平台和监控解决方案。

The rapid evolution of Large Language Models (LLMs) like GPT-3 has unlocked a new frontier in software development. However, building robust, production-ready applications with these models requires more than just API calls. It necessitates a suite of specialized tools for prompt engineering, data structuring, workflow orchestration, and performance monitoring. This post compiles and categorizes a selection of key tools and platforms that are empowering developers to build the next generation of LLM-powered applications.

以 GPT-3 为代表的大型语言模型（LLM）的快速发展，为软件开发开辟了新的前沿领域。然而，要利用这些模型构建健壮、可用于生产环境的应用程序，仅靠 API 调用是远远不够的。它需要一整套专门的工具，用于提示词工程、数据结构化、工作流程编排和性能监控。本文整理并分类了一系列关键工具和平台，这些工具正助力开发者构建下一代由 LLM 驱动的应用程序。
