the capabilities · 49 rules

What a model can do, decided by rules.

Vision, reasoning budgets, token-limit parameter names, JSON modes · the engine reads them from this ordered rule table, first match wins. The order is load-bearing and the resolution belongs to the engine: this page shows the rules, the binary applies them.
