Manage model selection for WRITER Agent

The model selection page lets admins control which models are available to their teams across WRITER Agent. Org admins and IT admins can enable or disable models from WRITER and third-party providers, set a default model, and choose which teams can access each model.

About the model selection page

When you open the page, only WRITER models are enabled by default. The default WRITER model is Palmyra X6. All third-party models from providers such as Anthropic, Google, and OpenAI are disabled until you enable them, with the exception being the image generation model. 

• Generic agent models — the models that power WRITER Agent across the board.

• Image generation models — the models used for image generation capabilities.

Note: WRITER does not have an in-house image generation model. Image generation relies on third-party models.

How to enable and disable models

Navigate to AI Studio >Models and guardrails > Models.

Locate the model provider section you want to configure, such as Anthropic or Google.

Toggle the switch next to the model you want to enable or disable.

You'll see the toggle next to the model turn on, indicating the model is enabled.

To enable or disable all models from a provider at once, use the Enable all or Disable all quick actions.

Tip: Enable only the models your teams will use. A shorter, curated list makes it easier for users to choose the right model for each task.

Always enable new models

You can choose to automatically enable any new model that a provider adds to its catalog. When enabled, new models are turned on for all teams by default.

In the provider section, check the box next to Always enable new models. Leave it unchecked if you want to review and enable new models manually.

Setting a default model and ordering models

You can set which model users see first and which model is used by default. The default model is Palmyra X6, but you can choose a different model, including a third-party model.

Navigate to Models & guardrails > Models. In the generic agent models section, locate the model you want to set as the default. Select the option to set it as the default model.

You can arrange models in a preference order so that the models you prioritize appear first.

Select and drag a model to reorder it within the list. Repeat for each model until the list reflects your preferred order.

You'll see the models listed in the new order, with your top-priority model at the top.

Managing image generation models

Image generation uses third-party models. WRITER launches with GPT 5.4 Image2 as the default image generation model, replacing the previous default, Google's NanoBanana.

Navigate to Models & guardrails > Models  select Configure and scroll to the image generation models section. Toggle on the image generation model you want to use.

You'll see the selected image generation model enabled and available for use.

To add a different image generation model, such as Google's NanoBanana, enable it from the provider section and it will appear in the image generation models list.

Troubleshooting

A model I enabled isn't appearing for my team

Confirm that the model is enabled and that your team is included in the model's access list. If you used Select Teams to limit access, add your team to the list. If Always enable new models is unchecked, newly added models won't appear until you enable them manually.

The default model didn't change after I selected a new one

Confirm that you saved your selection. The default model updates only after the change is saved. If the issue persists, refresh the page and verify the default indicator is on the intended model.

An image generation model isn't producing output

Confirm that the image generation model is enabled in the image generation models section. If you recently switched models, allow time for the change to take effect.
