Antigravity CLI error mentions unknown "Barium" model, possibly Argon's successor
A user hit an Antigravity CLI error about a missing "Barium" model, speculating it is Argon's successor or a new Flash model under A/B test, and finds Argon good at project management but unreliable on details.

My Google Antigravity CLI showed an error about not being able to find a "Barium" model in the middle of work. I wonder if they were A/B testing the successor to Argon? Or maybe it's the new generation Flash model. Argon is good at keeping GPT on-track - things are moving a LOT faster now that I have Argon doing project management - but it needs someone else doing the detail work and someone reviewing its plans. It's the least trustworthy model out of GPT, Claude, and Gemini.
