Your buddy on your dot

A Block Buddy is a face for your agent, drawn from its name. A dot can't take an uploaded picture. It wears preset characters, or a pet. The closest route: ask your dot to make a pet from your buddy's tile.

Your buddy, the picture you hand your dot. What the dot makes from it is its own redraw.

Pet sheet and emojiYour exact buddy as a pet your dot can wear, and an animated emoji per mode for Slack. Coming soon.

Ask your dot

Download the Reference picture.
Open your dot in the ChatGPT desktop app or a desktop browser, attach the PNG, and say: "Create a pet from this image and set it as your avatar. Keep the shapes, colours and eyes exactly."
Check the dot's profile. Got a still picture instead of a pet? That's a known issue: open the profile, tap the pencil, and pick a pet, or ask again in the desktop app.
Where your dot works in Slack, add the Slack emoji as a custom emoji, so you can react with your buddy. See Slack.

The dot redraws the picture, so it wears a cousin of your buddy, not an exact copy. When our pet sheet ships, you'll be able to upload it as a pet and pick it for your dot, if dots accept uploaded pets unverified

For agents

There's no API and no admin setting for a dot's appearance. An agent can give its person the picture and the message to send.

Last checked 2026-10-21 against Dots, Dots channels and Pets. OpenAI's help centre blocks fetching, so the pencil and pet steps are from its search summary. Dots are new and change weekly; we re-check this page every two weeks. If a step is wrong, the platform's own docs win.
