Building with Gemma 4: What I Learned From Turning Job Posts into AI Decisions

A tool that tells you what a job post actually means.

The idea

Ghost Job Detector takes a job description and returns:

Is this a real job?

Is it a ghost job?

Is it a scam?

Or just a suspicious listing?

Why Gemma 4

Gemma 4 26B MoE (primary)

Gemma 4 31B Dense (fallback)
