const model = new ChatGroq({
apiKey: process.env.GROQ_API_KEY, // Default value.
model: "llama-3.3-70b-versatile",
});
const message = new HumanMessage("What color is the sky?");
const res = await model.invoke([message]);Development

pnpm installBuild the package
pnpm buildOr from the repo root:
pnpm build --filter @langchain/groqRun tests
Test files should live within a tests/ file in the src/ folder. Unit tests should end in .test.ts and integration tests should
end in .int.test.ts:
$ pnpm test
$ pnpm test:intLint & Format
