What is rate limiting and how does it relate to 'ChatGPT an error occurred'?

Rate limiting is a mechanism to prevent abuse and ensure fair usage of the OpenAI API. It restricts the number of requests you can make within a certain time period. Exceeding the rate limit can trigger the 'ChatGPT an error occurred' message. You can check your usage dashboard in the OpenAI platform to understand your rate limits and request increases if needed.
