import { defineFlow, startFlowsServer } from '@genkit-ai/flow';
import { anthropic } from 'genkitx-anthropicai';

configureGenkit({

Basic examples

The simplest way to call the text generation model is by using the helper function generate:

// ...configure Genkit (as shown above)...

const response = await generate({
  model: claude3Haiku, // model imported from genkitx-anthropicai
  prompt: 'Tell me a joke.',
});

console.log(await response.text());

Multi-modal prompt

// ...configure Genkit (as shown above)...

const response = await generate({
  model: claude3Haiku,
  prompt: [
    { text: 'What animal is in the photo?' },
    { media: { url: imageUrl } },
  ],
  config: {
    // control of the level of visual detail when processing image embeddings
    // Low detail level also decreases the token usage
    visualDetailLevel: 'low',
  },
});
console.log(await response.text());

Within a flow

// ...configure Genkit (as shown above)...

export const myFlow = defineFlow(
  {
    name: 'menuSuggestionFlow',
    inputSchema: z.string(),
    outputSchema: z.string(),
  },
  async (subject) => {
    const llmResponse = await generate({
      prompt: `Suggest an item for the menu of a ${subject} themed restaurant`,
      model: claude3Opus,
    });

    return llmResponse.text();
  }
);
startFlowsServer();
