PromptLayer

PromptLayer is a platform for prompt engineering. It also helps with the LLM observability to visualize requests, version prompts, and track usage.

While PromptLayer does have LLMs that integrate directly with LangChain (e.g. PromptLayerOpenAI), using a callback is the recommended way to integrate PromptLayer with LangChain.

安装与设置​

要使用 PromptLayer，我们必须：

  • 创建一个 PromptLayer 帐户
