Support a verifiable slowdown
Propose reciprocal limits on training and deployment above agreed risk thresholds. Shared evaluations, incident communication, and public criteria should determine when development stops and resumes.
Open a channel between China and the United States
Offer Brazilian mediation for technical talks on evaluations, severe incidents, and deployment limits. Each side must be able to verify the measures without relying on political trust.
Prepare Brazil for coordination failure
Designate a permanent authority for advanced AI risks, preferring an existing body with technical staff over one built from scratch, map foreign dependencies, and exercise responses across finance, energy, communications, and public services.
Build inference sovereignty
Expand transmission, generation, and data centers with contractable capacity, a Brazilian contracting door, water limits, community consultation, and continuity for critical services. Segment workloads by supplier origin, offer anti-diversion verification to both blocs on Brazil's own initiative, and prefer several mid-sized projects over a single campus.
Measure and review results
Publish contractable capacity, water consumption, grid costs, and permanent jobs. Independent review and expiry dates should end programs that fail to deliver public benefits.
The meaning of slowdown
A generic pause offers no workable rule. An agreement needs capabilities, thresholds, and evaluations that trigger reciprocal limits, plus conditions for resuming training or deployment.
Data-center policy also needs measurable conditions. Pilots should measure price, access during incidents, water use, grid costs, and permanent jobs before benefits become entrenched.
From strategy to letter
The open letter translates these commitments for candidates and transition teams and defines results that can be assessed during the next term.
