Five models.
One answer.
Single-model answers hallucinate confidently. Five models from different providers rarely agree on the same wrong answer. When accuracy matters, run a council and let the disagreement surface before your agent acts on a bad output.
Multi-model verification on demand.
One model can hallucinate. Five rarely agree on the same wrong answer. Add mode: "council" to any request when accuracy matters more than latency. Pricing scales 5x to cover the parallel inference — honest, no hidden cost.
3–7 models answer in parallel
Diverse providers picked by topic and complexity. Avoids single-vendor bias and single-model failure modes.
Agreement scored
Embedding cosine similarity on paid tier, Jaccard word-overlap on free. Each answer gets an agreement score against the others.
Chairman synthesizes on disagreement
Confidence below 0.6? A separate Chairman model reads all answers and the critiques and synthesizes the final response.
Recommended for legal, medical, financial, and audit-grade prompts. For everyday traffic, default smart routing already picks the best single model — no need to pay 5x.

}Legal, medical, financial, audit. Anything where one hallucinated answer creates more damage than five right ones cost.
Latency-sensitive chat. Casual Q&A. Anything where a single smart-routed model already gets you 95% of the way.
