Welcome to the community!
You are talking about ChatGPT Plus, not API.
The limits for ChatGPt Plus, models are usage-based (measured by the number of messages you can send within a specific time frame) rather than based on tokens. Each model has a cap on the number of messages you can send, which resets after a defined period (e.g., every 3 hours, daily, or weekly).
Here are the usage limits for the four models as of now:
- GPT-4
• Limit: 40 messages every 3 hours.
- GPT-4o
• Limit: 80 messages every 3 hours.
- o1-preview
• Limit: 30 messages per week.
- o1-mini
• Limit: 50 messages per day.
