Error 429 is a rate limit error that is served to users who make too many requests to the ChatGPT API in a short period of time. This error can be caused by exceeding the quota of permitted requests or by using ChatGPT at a time when the network is very busy. Businesses using ChatGPT who find they have reached their API request limit should take steps to reduce their usage. Additionally, some users have encountered “login loops” after failing to verify their email addresses with OpenAI. If ChatGPT still isn’t working, there are other AI chatbot alternatives such as Chatsonic, YouChat, and Plerplexity.ai.
