I burned $110 trying to make a video ad for my SaaS.

So I built an AI tool to edit talking head videos for creators and to promote it I thought I'll create an AI UGC video. So just like everyone else I was scrolling Instagram, I came across SeedDance 2.5 model, I was impressed by the outputs. Now I had FAL AI account, so I connected it's MCP sever to claude code. With Claude I built few skill and created a pipeline for realistic avatar generation. The mistake I did was that i didn't check the cost of the model, as AI i

痛点：AI 视频/图像生成 API（如 FAL + SeedDance）的计费规则不透明，创作者在生成前无法预估总成本，一次性跑多版本就直接产生上百美元的意外账单。

目标用户：使用 FAL、Replicate 等平台跑 AI 视频/图像生成的独立开发者、SaaS 创始人、UGC 广告制作者和小型内容工作室。

证据：“The mistake I did was that i didn't check the cost of the model... At the end I opened the dashboard and saw $110 bill for today. 😭” / “these companies write it in a complicated fashion, so you don't know what you are signing up for.”

变现：Freemium：费用估算器免费，按项目保存预算与用量记录、超额告警、API 代理层强制预算上限（按调用量或订阅 9–29 美元/月）收费。

MVP：两周内做一个网页工具：输入模型（SeedDance、Kling 等）、场景数、每场景变体数、时长与分辨率，输出预估总价，并与历史实际账单做对比；再加一个轻量代理，可在 FAL/Replicate 调用前设置单次/单日预算上限，超过就中断并告警。

竞品：FAL AI 官方价格页/用量看板、Replicate 价格页、Helicone、Langfuse、OpenRouter 模型价格对比

摘要：一位做 AI 口播视频剪辑工具的 SaaS 创始人，为给自己的产品做广告，通过 FAL AI 的 MCP 接入 Claude Code 跑了 SeedDance 2.5 生成 UGC 视频，5 个场景每个 2 个变体，结果当天账单 110 美元，自己事先完全没看到模型单价。他总结的教训是：平台把定价写得很绕，必须先估算总时长成本、不要对贵模型跑多变体。这类“成本不可预见”的问题是做 AI 生成成本估算与预算护栏工具的机会，但帖中只有个人踩坑，尚无他人附和或明确付费表态。
