Daily Agent limit on Free
Free accounts can send 2 Agent messages per day. The day resets at 00:00 UTC. Questions to the core bots count toward the same 2, so Agent and core bots share one allowance. Custom bots, team chats and Researcher are Pro only.
Reset and boost
Your credits reset one month after your current period began. The exact date is under Usage on the Billing page. Pro accounts also get a Monthly boost of 10,000 credits once per period. Click Use boost to add it.
When you run out
You see "You're out of AI credits" with an upgrade option. Wait for the reset date, use the boost if you are on Pro, or upgrade. See Billing.
