Every control on the landing screen changes the search. None of them turn the lab into a chatbot.

Population size

This is how many sampled perspectives are generated for your wording — not how many API products you are paying for, and not a count of independent agents. Bigger N usually means more variety and a longer run. The hosted trial caps size; a saved Cerebras key unlocks the web options up to 500 (1,000 stays locked).

Search depth: quick vs balanced

Quick — generate, score, deepen the winners, synthesize. Built for the free-tier envelope.
Balanced — after scoring, the run mutates survivors and red-teams finalists before synthesis. Slower and more tokens. Hosted trial stays on quick; save a key to use balanced.

Web grounding

A switch, not a second product. It starts off. On runs a cheap web pass before casting (Scout) and an assumption check on finalists. Click-a-mind search still works either way. See Web search.

Attached files

Optional context, not a second problem. PDF, Markdown, text, PNG, or JPEG — up to four. The population reads a compressed brief. A scanned PDF with no text layer needs a screenshot instead.

Past runs

Your photo in the header opens the account page and lists searches you already ran. Opening one hydrates the lab from the saved snapshot. You are not resuming a live stream.

Hosted trial vs your Cerebras key

	Hosted trial	Your key
Runs	3 per Google account	Until your Cerebras budget says otherwise
Size / depth	Up to 50 minds, quick	Larger sizes, balanced
Deep research on a node	Locked	If you opt in on that mind

Your key never appears in the page after Save. Removing it returns you to the trial rules.

The canvas and a clicked mind

Each node is one seat in the population. Status (alive, discarded, deepened) is visible on the field. Click opens that seat: you can read the idea and run web search as that mind. Deep research is a separate, slower loop and only with a saved key.

The result

When the run converges you get one answer — title, how it works, first move, risks — not a transcript of every mind. Download markdown from the result sheet if you want to keep the pack.
