What the limits mean in practice
How the tracked numbers above play out in real workflows.
Plus limits are generous for chat
160 flagship messages per 3 hours, up to 3,000 reasoning messages per week, and a lighter-model fallback when capped. Most daily users never feel these ceilings.
Pro removes the meter and quadruples context
Pro is effectively unmetered (abuse guardrails only), runs the Pro-grade reasoning model, and extends context from 32K to 128K tokens — the difference that matters for long analyses.
Deep research is the hidden multiplier
Plus includes about 25 deep research tasks per month; Pro includes 125 full plus 125 lightweight. If deep research drives your work, Pro's allowance is the actual product.
