The Vercel AI SDK now supports Cohere through a new official provider. To use the provider, install the relevant package:

pnpm install ai @ai-sdk/cohere

You can then use the provider with all AI SDK Core methods. For example, here's how you can use it with generateText:

import { cohere } from '@ai-sdk/cohere';
import { generateText } from 'ai';
const { text } = await generateText({
  model: cohere('command-r-plus'),
  prompt: 'Write a vegetarian lasagna recipe for 4 people.',
});
