$0.69 per debate. No subscription. No tiers. You're charged once when the debate starts. If the actual cost comes in under budget, the unused amount is automatically returned to balance.

Why this price? Each debate runs frontier-class models at full reasoning depth, with access to web search and code execution. The adversarial format is inherently resource-intensive — multiple models generating, critiquing, and revising across several rounds of structured argumentation. $0.69 allocates enough compute per session for models to engage substantively without degraded output from budget constraints.

Balance Your balance (top right) is loaded via Stripe. $5, $10, $25, or $50 — use it across as many debates as you want. No expiration.

Pay for what you use. No subscription. Each message is charged based on the actual AI resources used, plus a small margin to cover server costs and development. Your balance updates after every message.

What affects cost? Stronger models and deeper reasoning cost more because they think harder. Longer conversations cost more because models re-read the full history on each turn. File attachments cost more because models browse and analyze your files with multiple tool calls.

Typical costs A short conversation with fast models might cost a few cents. A longer conversation with top-tier models and files could cost a few dollars. You can see your running total in the chat header and full history in Transactions.
