ChatGPT got worse — is it your IP?
When ChatGPT suddenly gives shorter, lazier answers or constantly makes you pass checks, the cause isn't single: OpenAI's model routing and A/B tests, account-level risk control, long context, and your network exit IP can all play a part.
Of those, the one you can verify in 30 seconds — and actually change — is the IP. An exit IP flagged as high-risk, datacenter, or non-native is more likely to trip OpenAI's risk control, which shows up as frequent human checks and rate limits.
Honestly: the IP is not the only cause and swapping it is no guarantee. But it's the cheapest lead to rule in or out. Below, check your current exit IP's risk score, whether it's datacenter/non-native, and whether ChatGPT is available in your region — clear the IP lead first.
