The main restriction is rate limiting tied to your ChatGPT subscription tier: reddit
- Plus users: Around 300–1,500 local messages every 5 hours, or 50–400 cloud tasks depending on complexity
- Pro users: Higher limits but still capped with 5-hour and weekly limits
- Usage counts against your overall ChatGPT subscription quota, not separate API credits github
