Max Rounds:

🔍 Grounded (web search) When enabled, each AI model can search the web for up-to-date information before answering. Useful for recent events, facts, or data that may be beyond the model's training cutoff. Adds a small per-query fee.

Verify current facts Available for Grounded debates. It checks narrowly scoped current factual inputs when sources are non-inspectable, secondary, conflicting, or stale; it prefers first-party sources and never decides a future prediction. No verifier is called when none qualify. This is evidence review, not a verdict. A run adds incremental model and web-search cost.
