Quick start
Two entry paths: work with the agent in the Agents tab, or call a saved Format over the API. Most teams do both — author in Agents, then invoke the recipe from their backend.
New to the product map? Read Sume basics first — Agents, Formats, Models, and which surface is primary for partners.

Option 1: Start it from one brief
Paste this into the composer at sume.com/agents. The thread keeps every artifact and approval.
Option 2: Work the thread
Use the Agents tab when a person should stay in the loop: brief, review, iterate, then save the result as a reusable recipe.
Open the Agents tab
Sign in and start a thread. Nothing to install.
Brief the agent
Describe the deliverable, not the tool calls. The agent picks the models, and asks before it spends.
Save the recipe as a Format
A Format is the same thread's recipe, addressable by handle and slug — that is what your backend calls later.

Need a single model call instead of a packaged workflow? Go straight to Create new avatar, Image 1.0, or the API recipes.
