Pick a scenario, or type anything in LIVE·REAL. Each scenario is chosen to expose a different kind of silent thought.

THE QUESTION WE ASK THE MODEL

The swap chips. Change one phrase and run again — the internal readout changes because the computation changes. This is your live "two words" moment.

Each glowing trace is a concept the model is silently holding — read from real activations, not from its output. X-axis = depth through the network.

The shaded band (layers ~38–92) is the workspace — where verbalizable thought concentrates. Remove what's here and multi-step reasoning collapses; routine tasks survive.

INTERNAL ACCESS · NOT EXPOSED
This is a live call to a closed-weight frontier API. The answer streams below — but no laboratory on earth can read its activations from out here. That asymmetry is the policy question.
