# Images

> Generating images in chat with a model from your own account, and the gallery that keeps them

Ask for a picture in any chat and the assistant generates one with an image
model from your own account. The images it makes are kept in your gallery until
you delete them.

## You bring the model

Image generation runs on a model you have added yourself, the same way every
other model in nemu works. Add one in the console under Models, with its type
set to Image, and it becomes available in chat straight away.

If you have no image model, the assistant says so and stops rather than
guessing. Nothing is generated and nothing is charged.

## Choosing which model runs

The first time a chat needs an image, you are asked which of your image models
to use. The prompt has one entry per model, and each model offers two ways in:

| Choice                       | What it does                                                   |
| ---------------------------- | -------------------------------------------------------------- |
| Use *model*                  | Generates this one image with that model                       |
| Use *model*, don't ask again | Pins that model for this chat, so later images skip the prompt |
| Deny                         | Nothing is generated                                           |

Pinning is remembered per chat, never across your whole account, so a new chat
asks again. Leaving the page while the question is open counts as a denial: the
request is dropped rather than left waiting.

## The gallery

Every generated image is listed at [chat.nemu.cc/gallery](https://chat.nemu.cc/gallery),
newest first, with the prompt that made it, its size and the chat it came from.
Select any number of images to delete them and free the space.

Images are not deleted on a timer. They stay until you remove them, which is why
the gallery has a storage meter in its header.

## Storage limits

Each plan has an image storage allowance, listed in [Plans](/plans), along with
a daily and weekly cap on how many images you can generate.

Storage is checked **before** anything is generated. When you are out of room
the assistant tells you to clear some images and links you to the gallery, and
no request is sent to the model, so a full gallery never costs you anything.

## Images in a Computer project

When a chat has a [Computer](/computer) project open, an image can be written
into the project as a real asset file rather than only shown in the
conversation. Ask for it in the project, for example a hero image for a page you
are building, and it lands in the project tree ready to reference from your
code.

An image saved into a project is a copy. Deleting it from the gallery does not
remove it from the project.

## Custom agents

`generate_image` is available to [custom agents](/chat/agents) as a tool. An
agent can only use a model you have already pinned in that chat, because an
agent running in the background has no way to ask you which model to use.
