Code examples

Basic example - text generation/inference

The following code examples authenticate with the environment variables. Please set environment variables before proceeding with examples:

const { WatsonXAI } = require('@ibm-cloud/watsonx-ai');

// Service instance
let watsonxAIService;

watsonxAIService = WatsonXAI.newInstance({
    version: '2024-05-31',
    serviceUrl: 'https://us-south.ml.cloud.ibm.com',
});

const textGenRequestParametersModel = {
    max_new_tokens: 100,
};

const params = {
    input: 'Generate a short greeting for project kick-off meeting.',
    modelId: 'google/flan-ul2',
    projectId: '<YOUR_PROJECT_ID>',
    parameters: textGenRequestParametersModel,
};

try {
    const textGeneration = watsonxAIService
    .textGeneration(params)
    .then((res) => {
        console.log("\n\n***** TEXT RESPONSE FROM MODEL *****");
        console.log(res.result.results[0].generated_text);
    })
} catch (err) {
    console.warn(err);
}

When you run this code, you should see result similar to the following output:

***** TEXT RESPONSE FROM MODEL *****
