How AI Wiki handles changing facts
Prices, model limits, lifecycle dates, and service status can change without warning. Each tool above shows when its data was last checked, or that it reads live feeds. Model facts, status cards and reset entries link to the provider sources they come from, and unknown values stay unknown instead of being guessed. Calculators are planning aids, not provider invoices or hardware guarantees.
