# GPT Pro Limits

Knowing what GPT Pro can and cannot do helps you plan how your team uses it. These limits keep the assistant fast and reliable for everyone. GPT Pro is a conversational AI assistant, so it does not upload documents, run plugins, or index a knowledge base.

# Platform

  • Microsoft Teams only: GPT Pro runs inside Microsoft Teams, in personal chats, group chats, and teams. It is not offered as a standalone web or desktop app.

# Message allowance

GPT Pro counts the messages each user sends within a rolling 3-hour window. The number of messages allowed in that window depends on your plan.

Plan Messages per rolling window
Free 5
Starter 30
Premium 100
Platinum 200
A bug that capped paying Premium subscribers at the free 5-message allowance has been fixed. A Premium license now gets the full 100 messages per rolling window.

# When you reach your allowance

GPT Pro pauses and posts an upgrade card in the chat. The card matches the plan you are on:

  • Free or Starter: you are offered Premium, with a Start a free Premium trial button and one month free, no commitment.
  • Premium: you are offered Platinum, which has the highest allowance and priority support. Platinum has no free trial.
  • Platinum: you see a plain notice that you reached your message limit for now, with no upgrade offer, because Platinum is the top plan.

The pause is temporary. GPT Pro answers again as soon as your earlier messages age past the 3-hour window. Compare tiers on the pricing and subscription page.

# Response length

Each reply is generated with up to about 4,000 tokens. Very long requests may be answered in a summarized form. Ask a follow-up question if you need more detail.

# Conversation memory

GPT Pro remembers the earlier messages in your current conversation so it can keep context across turns. Starting a new conversation begins with a clean history.

# Language

GPT Pro replies in the language of your message. If your language is not supported, it responds in English. The interface is available in English, French, German, Italian, Portuguese, and Spanish.

# Content restrictions

For safety, GPT Pro declines questions about restricted topics such as war, weapons, drugs, medical or sexual advice, and politics or religion outside an educational context. For the full policy, see content filtering.
