DeepInfra

LangChain 通过 DeepInfra 封装器支持 Deep Infra 所托管的 LLM。
首先,你需要安装 @langchain/community 包:

:::提示 请参阅安装集成包的一般说明部分。 :::

npm install @langchain/community @langchain/core

你需要获取一个 API 密钥,并将其设置为名为 DEEPINFRA_API_TOKEN 的环境变量(或者直接传入构造函数),然后按照以下方式调用模型:

import { DeepInfraLLM } from "@langchain/community/llms/deepinfra";

const apiKey = process.env.DEEPINFRA_API_TOKEN;
const model = "meta-llama/Meta-Llama-3-70B-Instruct";

const llm = new DeepInfraLLM({
temperature: 0.7,
maxTokens: 20,
model,
apiKey,
maxRetries: 5,
});

const res = await llm.invoke(
"What is the next step in the process of making a good game?"
);

console.log({ res });
