import { ChatNovitaAI } from "@langchain/community/chat_models/novita";

const llm = new ChatNovitaAI({
  model: "meta-llama/llama-3.1-8b-instruct",
  temperature: 0,
  // other params...
})

Invocation

const aiMsg = await llm.invoke([
  {
    role: "system",
    content: "You are a helpful assistant that translates English to French. Translate the user sentence.",
  },
  {
    role: "human",
    content: "I love programming."
  },
]);

console.log(aiMsg.content)

Chaining

We can chain our model with a prompt template like so:

import { ChatPromptTemplate } from "@langchain/core/prompts"

const prompt = ChatPromptTemplate.fromMessages(
  [
    [
      "system",
      "You are a helpful assistant that translates {input_language} to {output_language}.",
    ],
    ["human", "{input}"],
  ]
)

const chain = prompt.pipe(llm);
await chain.invoke(
  {
    input_language: "English",
    output_language: "German",
    input: "I love programming.",
  }
)
