PromptLayer OpenAI
==================

LangChain integrates with PromptLayer for logging and debugging prompts and responses. To add support for PromptLayer:

1.  Create a PromptLayer account here: [https://promptlayer.com](https://promptlayer.com).
2.  Create an API token and pass it either as `promptLayerApiKey` argument in the `PromptLayerOpenAI` constructor or in the `PROMPTLAYER_API_KEY` environment variable.

    import { PromptLayerOpenAI } from "langchain/llms/openai";const model = new PromptLayerOpenAI({  temperature: 0.9,  apiKey: "YOUR-API-KEY", // In Node.js defaults to process.env.OPENAI_API_KEY  promptLayerApiKey: "YOUR-API-KEY", // In Node.js defaults to process.env.PROMPTLAYER_API_KEY});const res = await model.invoke(  "What would be a good company name a company that makes colorful socks?");

Azure PromptLayerOpenAI
=======================

LangChain also integrates with PromptLayer for Azure-hosted OpenAI instances:

    import { PromptLayerOpenAI } from "langchain/llms/openai";const model = new PromptLayerOpenAI({  temperature: 0.9,  azureOpenAIApiKey: "YOUR-AOAI-API-KEY", // In Node.js defaults to process.env.AZURE_OPENAI_API_KEY  azureOpenAIApiInstanceName: "YOUR-AOAI-INSTANCE-NAME", // In Node.js defaults to process.env.AZURE_OPENAI_API_INSTANCE_NAME  azureOpenAIApiDeploymentName: "YOUR-AOAI-DEPLOYMENT-NAME", // In Node.js defaults to process.env.AZURE_OPENAI_API_DEPLOYMENT_NAME  azureOpenAIApiCompletionsDeploymentName:    "YOUR-AOAI-COMPLETIONS-DEPLOYMENT-NAME", // In Node.js defaults to process.env.AZURE_OPENAI_API_COMPLETIONS_DEPLOYMENT_NAME  azureOpenAIApiEmbeddingsDeploymentName:    "YOUR-AOAI-EMBEDDINGS-DEPLOYMENT-NAME", // In Node.js defaults to process.env.AZURE_OPENAI_API_EMBEDDINGS_DEPLOYMENT_NAME  azureOpenAIApiVersion: "YOUR-AOAI-API-VERSION", // In Node.js defaults to process.env.AZURE_OPENAI_API_VERSION  azureOpenAIBasePath: "YOUR-AZURE-OPENAI-BASE-PATH", // In Node.js defaults to process.env.AZURE_OPENAI_BASE_PATH  promptLayerApiKey: "YOUR-API-KEY", // In Node.js defaults to process.env.PROMPTLAYER_API_KEY});const res = await model.invoke(  "What would be a good company name a company that makes colorful socks?");

The request and the response will be logged in the [PromptLayer dashboard](https://promptlayer.com/home).

> **_Note:_** In streaming mode PromptLayer will not log the response.
