I purely intended to use it for review and architectural design given my bad experiences with Gemini coding. The bad experience stemmed from it getting stuck in loops and burning quota. The code quality when it worked was great.
I now asked Argon for a pretty elaborate review and it used only 2% so I will be giving it another shot.
Another thing that can be of influence is that for subscriptions, Google uses some proprietary idea of “work done” for the quota instead of simply how many tokens were burned. I can imagine that this heuristic is sometimes quite off.
