So I needed some use for **Gemini 4 Argon**, the brand-new **frontier-level** model from Google. Even though Google gave up their "Don't be evil" motto years ago, they are still a major player in the tech world. When I write a **blog post**, my **Rust code** needs to insert both a title and a file name.

The **file name** can be **derived** from the title, but with stopwords like "and" removed, and with hyphens instead of spaces. So "Title and Example" becomes "title-example". I sent a **prompt** to Gemini 4 Argon for this function, as it never was important enough for me to write on my own.

Gemini 4 Argon responded **nearly instantly** and it only took 1,178 tokens and 15.2 seconds. The cost was $0.014; I will never see that money again, but I hope someday to earn it back. The **generated Rust code** was **superb**. It **worked correctly** the first time I pasted it into my MCP server. So this means Gemini 4 Argon can be responsible for generating my blog post file names.
