does chatgpt pro plan really offer "unlimited" requests to models? so I can send like 100000 requests to the model o3 in one day? if not, please tell me the real limit. you can search the web
ChatGPT Pro advertises “unlimited” access to the o-series and GPT-4-family models for normal chat messages, but that does not mean you can hammer the service with 100 000 scripted requests in a day.
Plan | o3 usage cap | o4-mini-high | o4-mini | Notes |
---|---|---|---|---|
Free | Not offered | small daily pool | small daily pool | hard-throttled & cooldowns |
Plus / Team / Enterprise | 100 messages per week help.openai.com | 100 / day help.openai.com | 300 / day help.openai.com | resets rolling at 00:00 UTC on day 7 |
Pro ($200 / mo) | Advertised as “unlimited” help.openai.com | unlimited | unlimited | still subject to abuse guard-rails & ToS |
No fixed weekly/daily quota for normal chat messages.
Unlike Plus, Pro does not cut you off after 100 o3 messages per week; there is no public numeric ceiling. help.openai.com
Dynamic rate-limits still exist.
If the system detects behaviour that looks automated (very high frequency, identical prompts, etc.) you will see a “Slow down / Rate-limit” banner or a temporary lockout.
Terms of Use forbid scripted extraction.
The ToS explicitly bans “automatically or programmatically” extracting data from ChatGPT and forbids attempts to bypass rate limits. openai.com
Sending 100 000 requests in one day would clearly require automation and would violate that clause, so you would be throttled or suspended long before you reached the target.
Feature-specific quotas still apply.
Deep research queries, for example, are capped even on Pro (250 full-strength runs per month). openai.com
Similar per-feature limits exist for video/voice, image generation, file uploads, etc.
Operational guard-rails.
OpenAI reserves the right to impose temporary limits “to prevent misuse” and restore access after manual review. help.openai.com
So, yes—Pro removes the headline message cap, but it is “unlimited within fair-use boundaries,” not an infinite fire-hose for bots.
