Show HN: ChatGemini – Easy tool, >50% cost saved with cache, multi(NL video edit

https://github.com/Saki-tw/ChatGemini_SakiTool
2•Saki2007•3h ago
Hi HN,

This started as a simple script for my own workflow to optimize Gemini API costs using caching (often seeing 50-95% savings). Over time, I gradually added features I found useful, including wrappers for Veo 3.1 generation and a natural language video editor I call Flow Engine.

*Fair warning: The current UI and detailed docs are primarily in Traditional Chinese as it originated from personal use.* However, the underlying concepts (especially around caching strategy and the Flow Engine approach to video editing) might be interesting to the HN community.

Hope some find the ideas or code useful. Happy to answer questions!
