    1. we made a 27b model for creative writing. performs as good as claude fable 5, at a 40x cheaper price, open weights.
    2. I built a confidence-gated router (Jev + LLM) that only calls the LLM when it's worth it
    3. My LLM reviewer was rewarding users for adding requirements the task never had
