title: Generate Images
---


You can use Quivr to Generate Images using Dall-E 3 from OpenAI or any other API based image generation tool.  
This allows you to leverage image generation by creating a brain that is connected to Dall-E. 


## OpenAI

<Info>
In order to have image generation in Quivr we will create a brain that is connected to an API. You can find more info on this types of brains [here](/getting-started/api-based-brains)
</Info>

<Steps>
<Step title="Create OpenAI Account">
    Create an account on [OpenAI](https://platform.openai.com/)
</Step>
<Step title="Credit Card">
    To get access to image generation, add your credit card in the `billing` section
</Step>
<Step title="Create API Key">
    Create on API Key and save the result
</Step>
</Steps>

<Warning>
Do not share your API Key
</Warning>

## Create a brain

Now it is time to create an App brain. This type of brain allows you to interact with APIs. And that is exactly what we need to do now. Let's get started.

<Warning>
Generating images costs around 2cts per image. Be carefull or you'll have a surprised bill.  
</Warning>

<Steps>
<Step title="Create a new Brain">
    Go to the [Brains](https://www.quivr.app/brains-management) page and click on `Create Brain`
</Step>
<Step title="Choose App Brain">
    Select `App (Through API)` and click on `Next` 
</Step>
<Step title="Name & Prompt">
    1. Give your brain a name.
    2. Add this as your description.
    ```
    You generate only one image and use markdown to display the url sent as a result and you need to keep the entire url with all the parameters for the image to be displayed correctly. 
    Do not remove the signature and password in the url of the image as it is a signed url.  
    Also return the revised prompt below the image in italic. 
    If the user ask for a modification use the previous prompt generated as base
    ```
    3. Click on `Next`
</Step>
<Step title="URL">
    1. Select `POST` as the method
    2. Add this as the url `https://api.openai.com/v1/images/generations`
    <img src="/images/openai-brain-url.png"/>
</Step>
<Step title="Parameters">
    1. Add `prompt` as a parameter and click on `Required`
        <ParamField path="prompt" type="string">
            Description of the image to generate
        </ParamField>
    2. Add `size` as a parameter and click on `Required`
        <ParamField path="size" type="string">
            By default 1024x1024 . But  images can have a size of 1024x1024 (square), 1024x1792 (vertical) or 1792x1024 (horizontal) pixels
        </ParamField>
    3. Add `model` as a parameter and click on `Required`
        <ParamField path="model" type="string">
            Either dall-e-3 or dall-e-2. By default dall-e-3
        </ParamField>

</Step>
<Step title="Secrets">
    1. Add `Authorization` as a secret
        <ParamField path="Authorization" type="string">
            Bearer YOUR_API_KEY
        </ParamField>
        **Add your API Key in the value**
    2. Add `Content-Type` as a secret and click on `Required`
        <ParamField path="Content-Type" type="string">
            application/json
        </ParamField>
        **Add `application/json` in the value**
    <img src="/images/openai-brain-secrets.png"/>
</Step>
<Step title="Create">
    Click on `Create`
</Step>
<Step title="Generate your image">
    Go to the chat and ask a question to your newly created brain.
    <Tip>
    You might have to type `@` and select your brain to be able to ask a question to it.

You can now use this brain to generate images. You can also use it to generate images in your own app throught the API.
