If ChatGPT is showing a "Too Many Requests" or error 429 message, you've hit the service's usage rate limit. This guide explains why it happens, how long it lasts, and what you can do right now.
Quick summary: Wait 30–60 minutes for the free plan limit to reset, or upgrade to ChatGPT Plus for higher limits and priority access during peak hours.
Why ChatGPT Shows "Too Many Requests"
You have exceeded the hourly message limit on the free plan
OpenAI's servers are under high load and throttling requests
You are using a shared IP (office, school, VPN) that has collectively exceeded limits
A browser extension or automation script is sending too many requests
GPT-4 has a separate, lower hourly cap even on ChatGPT Plus
