Sidebar
All nodes can be found on your lab's sidebar. The only non-node button on your sidebar is the "Duplicate lab" button at the top.
AI nodes
We have 5 model nodes that can be imported to your canvas. These are main nodes that tipically perform a cognitive function in workflows and have supporting nodes in the "Utility Nodes" submenu.
Utility nodes
The last button on the sidebar opens up a submenu that has utility nodes under it. You can find all nodes that connect to their respective main AI node here.
