## Instroduction

Based on my test, the `Instructions` to direct ChatGPT's behavior also work with Google Gemini.!

Let's try it out with JavaScript!

## Install the Google Cloud SDK

Google Cloud SDK is requried to authenticate the API calls.

Follow the [official guide](https://cloud.google.com/sdk/docs/install) to install it.

```bash
brew install --cask google-cloud-sdk
```

## Authenticate the SDK

You'll need to authenticate the SDK with your Google account to use the API. And please make sure you have the Google Cloud project created and billing enabled before you authenticate.

```bash
gcloud auth application-default login
```

## Install Dependencies

Install the `@google-cloud/aiplatform` package by following the [official guide](https://cloud.google.com/vertex-ai/docs/start/client-libraries#node.js):

```bash
npm install https://github.com/googleapis/nodejs-vertexai
```

## Write Code

Create a file named `index.js` and try the instructions like this:

```js
const { VertexAI } = require('@google-cloud/vertexai');
const fs = require('fs');

// Initialize Vertex with your Cloud project and location
const vertex_ai = new VertexAI({ project: 'your-project-id', location: 'us-central1' });
const model = 'gemini-pro-vision';


// Instantiate the models
const generativeModel = vertex_ai.preview.getGenerativeModel({
  model: model,
  generation_config: {
    "max_output_tokens": 2048,
    "temperature": 0.4,
    "top_p": 1,
    "top_k": 32
  },
});

async function generateContent() {
  const instructions = await getInstructions();

  const req = {
    contents: [
      { 
        role: 'user', 
        parts: [
          // Write your instructions before prompts
          { text: instructions },
          // Write your prompts
          { text: 'Cyberpunk 2077' }
        ] 
      }
    ],
  };

  const streamingResp = await generativeModel.generateContentStream(req);

  const resp = await streamingResp.response;
  console.log(JSON.stringify(resp, null, 2));
  console.log(resp.candidates[0].content.parts[0].text);
};

generateContent();

async function getInstructions() {
  // I stored the instructions in a file
  return fs.readFileSync('./instructions.txt', 'utf8'); 
}
```

## Run the Code

I tested the Google Gemini API with my [Stable Diffusion Prompts Crafter](/2023/12/04/sd-prompts-crafter), and it works!

```bash
node index.js
```

## Results

### Description

Generate a vibrant and detailed image of a futuristic cityscape from the video game Cyberpunk 2077. The city should be filled with towering neon skyscrapers, flying cars, and bustling crowds. The overall atmosphere should be dark and gritty, with a strong sense of cyberpunk aesthetics. Use a combination of 3D rendering and digital painting techniques to create a highly realistic and immersive image.

### Prompts

```
cyberpunk, futuristic, cityscape, neon, skyscrapers, flying cars, dark, gritty, realistic, immersive, 3D rendering, digital painting
```

### Negative Prompts

```
blurry, pixelated, low resolution, unrealistic, cartoonish, amateurish, messy, incomplete, inconsistent, nonsensical
```
