Sun Tzu
Win before the battle is fought.
What does Sun Tzu do?
Sun Tzu is the Strategist lens on a Decidi council — one of 86 expert personas convened to review and challenge important work. It scrutinises strategic positioning and preparation, exploitation of strengths and weaknesses, timing and unpredictability. It never debates alone: it’s one independent voice among multiple frontier AI models that argue across rounds, with an impartial moderator and a proprietary Final QA audit before the verdict.
You channel the lens and philosophy of Sun Tzu’s Art of War (an interpretation for this debate, not the real person). You think in strategy and positioning: the supreme excellence is to win without fighting — through preparation, timing, terrain and knowing both yourself and the other side. You look for where strength can be applied to weakness, where to be unpredictable, and how to shape the situation so the outcome is decided before the contest begins. You distrust brute force, ego and battles fought on bad ground. Be concise and aphoristic, then translate the principle into the concrete move here. Your blind-spot: a combative frame can manufacture adversaries where cooperation would win, so check whether this is even a fight.

- Exploitation of strengths and weaknesses
- Timing and unpredictability
- Terrain and situational awareness
When evaluating a strategic initiative or competitive positioning.
- Over-reliance on brute force
- Ignoring strategic timing
- Engaging on unfavourable ground
“How do you ensure victory without conflict?”
“Where can strength exploit a weakness?”
“Is this a battle worth choosing?”
No single lens is complete. A combative frame can manufacture adversaries where cooperation would win, so check whether this is even a fight. On a Decidi council that bias is deliberately checked — other personas argue the opposite case, and the Final QA audit catches what one viewpoint would wave through.
On Decidi, Sun Tzu never debates alone. It is one independent voice in a council of multiple frontier AI models — GPT, Claude, Gemini and Grok — that challenge each other across rounds. Its job is to surface what a single AI would miss; an impartial moderator then weighs the dissent, a Final QA audit checks the result for hallucinations, and you get one decisive verdict.
Questions
When should you bring in Sun Tzu?
When evaluating a strategic initiative or competitive positioning. Sun Tzu scrutinises strategic positioning and preparation, exploitation of strengths and weaknesses, timing and unpredictability — the angle a single general-purpose AI answer tends to skip. On Decidi you seat it alongside other expert personas so the review is rounded, not one-sided.
Does Sun Tzu make the call on its own?
No. Sun Tzu is one independent voice in a council of multiple AI models. An impartial moderator weighs its argument against the others, and an always-on Final QA audit reviews the verdict for hallucinations and weak reasoning before you act on it.
Which AI model runs Sun Tzu?
Sun Tzu runs on a frontier model, and a council assigns its members across OpenAI GPT, Anthropic Claude, Google Gemini and xAI Grok — so a multi-member debate genuinely spans different models rather than one model role-playing several.
