A: Currently, we have yet to launch the option for additional purchase of credits, mainly because our existing plans already meet the needs of most users. However, we highly value your feedback and will assess the feasibility of introducing the option for additional credit purchase based on the usage of the users.

Additionally, regarding the pay-per-use credits, though it may support all features that your existing plan offers, there may be certain limitations. For example, due to constraints from the OpenAI API, we are still evaluating the usage rules and limitations of the current GPT Image feature. Specifics of the usage rules and limitations will be further detailed at a later date.
