HuggingFaceInference

Here's an example of calling a HugggingFaceInference model as an LLM:

• npm
• Yarn
• pnpm

npm install @langchain/community @langchain/core @huggingface/inference@4

tip

We're unifying model params across all packages. We now suggest using model instead of modelName, and apiKey for API keys.

import { HuggingFaceInference } from "@langchain/community/llms/hf";

const model = new HuggingFaceInference({
  model: "gpt2",
  apiKey: "YOUR-API-KEY", // In Node.js defaults to process.env.HUGGINGFACEHUB_API_KEY
});
const res = await model.invoke("1 + 1 =");
console.log({ res });
