How an AI Agent Works

A simulated interactive demo

Register to try the lab

Everything below is real — it's just switched off until you register, so you can see exactly what you'd be trying first. It only takes an email and a name.

How the loop works

The demo below runs this exact loop: read_slot and write_slot are the tool calls, and each card is labeled "Loop 1," "Loop 2," or "Loop 3" to show which trip around the loop it belongs to.

The loop

One step = one round trip: the model checks the state, picks one tool call, sees the result, decides what's next. Press Next step to watch it happen.

Stateless

The model remembers nothing between calls, so the whole chat resends every step — that's the color blocks on the right; hover one for its JSON.

The slots current values

max 18 steps

Your prompt

Slots A, B, C, and D each hold a number, currently in the wrong order. Compare each slot to its neighbor — A to B, B to C, C to D — and swap any pair that's backwards. Keep sweeping through until nothing's left to swap, so A ends up smallest and D largest.

Color blocks for each step fill in here as you go.
