A second opinion is only useful if it's truly independent. CouncilMind runs your question through four frontier models in parallel—GPT-5, Claude Opus 4.6, Gemini 2.5 Pro, DeepSeek V4 Pro—and surfaces exactly where they disagree.
The standard answer is X. Most sources agree.
X is right in the typical case, but the question implies the edge case—where Y is correct.
Synthesis: X is the right default; Y kicks in when the user's premise is the edge case implied here.
The same training data produces correlated mistakes
Different model families, different training pipelines, different biases. When they agree, the answer is robust.
The most useful output isn't the consensus—it's the dissent. That's where the verification work goes.
Run a skeptic pass to find the strongest counter-argument to any answer.

The synthesis explicitly marks where models disagreed and what to verify.
