Perplexity Pro users can generate images directly inside the search interface. By default, the platform may use a different image generation model than the one you prefer. This article shows you how to set a specific image generation model as your default for all future image requests.
The feature is available only to Perplexity Pro subscribers. Free accounts do not have access to image generation or model selection. Once you set a default model, every new image prompt will use that model unless you manually change it in a specific query.
You can choose from models such as DALL-E 3, Stable Diffusion XL, or other supported engines. The default setting applies across all your devices when you are signed in to the same Perplexity Pro account.
Key Takeaways: Setting Your Image Generation Model Default in Perplexity Pro
- Settings > Image Generation > Default Model: Select your preferred model from the dropdown to set it as the default for all image prompts.
- Model availability depends on your subscription: Only Pro subscribers can access multiple image generation models and set a default.
- Manual override per query: You can still switch models for individual requests without changing the global default.
Understanding Image Generation Models in Perplexity Pro
Perplexity Pro integrates image generation through partnerships with third-party model providers. The available models include DALL-E 3 from OpenAI, Stable Diffusion XL from Stability AI, and others that may be added or removed over time. Each model produces different styles, resolutions, and levels of detail. DALL-E 3 is known for high photorealism and strong adherence to prompts. Stable Diffusion XL offers more artistic flexibility and faster generation on some hardware.
When you generate an image without specifying a model, Perplexity uses the default model set in your account settings. If you have not set a default, the system uses its own internal default, which is typically DALL-E 3. Changing the default ensures that every new image request starts with your chosen model, saving you the extra step of selecting it each time.
The default model setting is stored on Perplexity’s servers and linked to your Pro account. This means the setting syncs across all devices where you are logged in, including web browsers, mobile apps, and desktop clients. There is no need to configure it separately on each device.
Prerequisites for Setting the Default Image Generation Model
Before you can set a default model, you must meet these requirements:
- An active Perplexity Pro subscription. Free accounts cannot use image generation.
- A web browser or the Perplexity mobile app (iOS or Android) signed into your Pro account.
- Access to the Settings menu. The option is not available from the search bar or image generation dialog alone.
If you have a Pro subscription but do not see the image generation settings, try logging out and logging back in. You may also need to clear your browser cache or update the mobile app to the latest version.
Steps to Set the Image Generation Model Default
Follow these steps to change the default image generation model in Perplexity Pro. The steps are the same for web, iOS, and Android.
- Open Perplexity and sign in to your Pro account
Go to perplexity.ai in a web browser or open the Perplexity mobile app. Make sure you see the Pro badge on your profile icon. If you do not see it, check your subscription status in Account > Subscription. - Click your profile icon in the top-right corner
The profile icon is a circle with your initials or a generic avatar. A dropdown menu appears with options including Settings, Account, and Log Out. - Select Settings from the dropdown menu
The Settings page opens. It contains sections for Account, Appearance, Language, and Image Generation. Scroll down if needed. - Click the Image Generation tab or section
On web, the tab is labeled Image Generation and sits between Language and Privacy. On mobile, look for a row labeled Image Generation with a right arrow. - Find the Default Model dropdown
This dropdown lists all available image generation models. The currently selected model is shown. If you have never changed it, it likely says DALL-E 3 or Default. - Click the dropdown and select your preferred model
Choose from the list. Options may include DALL-E 3, Stable Diffusion XL, or others. The selection is saved automatically. No Save button is required. - Test the new default by generating an image
Go back to the main search page. Type a prompt such as a cat wearing a hat and press Enter or click the image icon. The generated image should use your newly selected model. You can verify the model name in the response details if available.
If the Default Model Does Not Apply
Default Model Resets After a Few Days
Some users report that the default model reverts to DALL-E 3 after a few days. This is likely a bug. To work around it, set the default again and check if the setting persists. If it keeps resetting, contact Perplexity support through Settings > Help > Contact Us.
Model Not Listed in the Dropdown
If a model you expect to see is missing, it may not be available in your region or on your device. Model availability can vary by geographic location and platform. For example, Stable Diffusion XL may not be listed on iOS due to App Store restrictions. In that case, use the web version on a desktop computer.
Image Generation Not Working at All
If you cannot generate images even after setting a default, check your subscription status. Go to Settings > Account > Subscription. If your Pro subscription has expired or payment failed, image generation is disabled. Renew your subscription to restore access.
Perplexity Pro Image Generation Models Comparison
| Item | DALL-E 3 | Stable Diffusion XL |
|---|---|---|
| Developer | OpenAI | Stability AI |
| Best for | Photorealistic images and complex prompts | Artistic styles and fast generation |
| Output resolution | 1024×1024 pixels (fixed) | 512×512 to 1024×1024 pixels (configurable) |
| Prompt adherence | High | Moderate to high |
| Speed | Slower due to server processing | Faster on supported hardware |
| Availability on mobile | Yes (iOS and Android) | Web only (not on iOS) |
You can set either model as your default. The choice depends on whether you prioritize photorealism or artistic flexibility. If you use both models regularly, keep the default set to your most-used model and switch manually for the other.
Common Mistakes When Setting the Default Model
Not Signing In With the Correct Account
If you have multiple Perplexity accounts, ensure you are signed into the one with an active Pro subscription. The default model setting is tied to the account, not the device. Check the email address shown in Settings > Account.
Expecting the Default to Apply to Existing Conversations
The default model only applies to new image prompts. Existing conversations or previously generated images are not affected. To use the new default in an existing conversation, start a new thread or use a fresh prompt.
Confusing Default Model With Model in a Specific Query
When you manually select a model for a single query, that selection overrides the default for that query only. The default remains unchanged for future queries. If you want the manually selected model to become the new default, go back to Settings and update the Default Model dropdown.
Now you can set your preferred image generation model as the default in Perplexity Pro. This eliminates the need to select a model every time you generate an image. For best results, test both DALL-E 3 and Stable Diffusion XL to see which model matches your typical use case. If you frequently switch between models, consider leaving the default as DALL-E 3 and using the manual override for artistic prompts that benefit from Stable Diffusion XL.
