How to change between image models in Assist (and what each one does)

Assist offers several image-generation models. You can choose a model in an image template’s settings, or leave the template set to your organisation’s default.

You don’t need to create a separate template for every model. If suitable image templates already exist in your Library, you can select one from chat.

Available model options

GPT Image 2.5 supports creating images, editing images and including text within generated designs. Always check the result, particularly spelling, small text and brand details.

Change a template’s image model

You’ll need access to edit the template.

1. Open Library from the left-hand sidebar.
2. Select Templates.
3. Find the image template and click Edit Template.
4. Scroll to Image Output Settings.
5. Open Image Generation Model.
6. Choose the option you want.
7. Click Update Template.

The selected model applies when you use that template for subsequent image generation.

Editing a shared template can affect other people who use it. Check that the change is appropriate before updating it.

Use an existing image template in chat

1. Open a chat.
2. Click Library near the message input.
3. Search for the image template.
4. Select it and describe the image you want.

For example:

Create a square poster for a fictional coffee shop, with the headline “Your morning starts here”.

Templates may have names that describe their model, such as GPT 2.5 Flare Image Generator or GPT 2.5 Sunburst Image Generator. Check the template’s settings if you need to confirm which model it uses.

Which option should I choose?

• Exploring ideas quickly: try GPT Image 2.5 Flare (Faster).
• Working on a detailed image: try GPT Image 2.5 Sunburst (Higher quality).
• Following your organisation’s preferred setup: use Inherit from organisation.
• Comparing results: try the same prompt with different model templates and review which best suits your brief.

Model choice is one part of the result. Your prompt, reference images and template instructions also matter.

Edit an image or include text

You can ask for changes in the same chat. Be clear about which image to edit and what should change.

Example:

Edit image #1. Keep the bottle purple, change the background to cream and add the words “Refill. Reuse. Repeat.”

For text within a design, put the exact wording in quotation marks and explain where it should appear.

Generated text can still contain mistakes. Check it before sharing or publishing the image.

How many images will I get?

Assist generates one image by default. If you want more, specify the number in your request.

Example:

Create three different versions of this poster.

Common questions

Is GPT Image 2.5 available in Assist?

Yes. The model options include GPT Image 2.5 Flare (Faster) and GPT Image 2.5 Sunburst (Higher quality).

Can GPT Image 2.5 edit images and include text in designs?

Yes. GPT Image 2.5 supports image editing and creating text within generated designs.

Is GPT Image 2 still available?

Yes. GPT Image 2 remains a separate option in the model dropdown.

What does “Inherit from organisation” mean?

The template uses the image model selected as your organisation’s default. If that default changes, templates using this setting follow it.

Do I need a separate template for every model?

No. Separate templates are an optional way to make switching easier. Use an existing suitable template where possible.

I can’t find a template in chat. What should I check?

Check its visibility and whether it is enabled. Private templates are only available to their owner. To make one available more widely, use the appropriate Promote option in the Library.
