WHICH ONE IS FOR YOU?
━━━
📱 I'm on a phone or old laptop
Stick with Cerberus 4B. It’s lighter, faster, and still unfiltered. This new one will choke your machine.
💻 I have 16GB+ RAM and a decent GPU
Grab Arbiter GL9B. You’ll feel the jump instantly — deeper answers, better reasoning, fewer “close but not quite” replies.
🤷 I have no idea what any of that means
Grab both. Keep the one your machine likes. If Arbiter runs slow on your computer, delete it and stick with Cerberus 4B. No harm done.
🎮 I'm a gamer with a good PC
Arbiter GL9B, no question. If your rig runs modern games at decent settings, it’ll run this model comfortably.
