The cost of AI-generated content is dynamic: sometimes, for the same 7-second video, a long inference run can cause costs to skyrocket; concurrency, queuing, and retries can all make single-transaction costs uncontrollable. So I spent a lot of time on two things: Cost monitoring: The actual cost per function, per generation, and per second of video must be statistically calculated. Points system: Convert dollar costs into "points" that users can understand, while ensuring long-term profitability. If this isn't done well, the product can easily fall into the situation where "the more users use it, the more you lose." For independent developers, this is almost fatal.
I discovered that "parent-child/baby" content has a natural power to spread on social media platforms—whether it's cute, funny, heartwarming, or topics like "what will the future baby look like?", people can't help but click, comment, and share.
