Model selector makes it hard to find cheap/unlimited models

I'm a Pro user (100 VVV staked) and I burned through roughly 900 credits in a single day before I even realized which models were costing me. My balance went from 1,000 to 100, and I had to go to the credit purchase screen to figure out that 100 credits = $1.

The core problem: the model selector presents dozens of "frontier" models that look equivalent at a glance, but their credit costs vary enormously. There's no clear, persistent label showing which models are unlimited under Pro, which are cheap, and which will drain your balance fast. I ended up defaulting to an expensive model because it was near the top of the list and looked like a reasonable choice.

A few specific suggestions:

1. Label models by tier in the selector. "Unlimited," "Low cost," and "Premium" badges, or at minimum a visible credit-per-message estimate next to each model name, before you open the chat.

2. Sort, group or filter by cost. A "Budget" or "Unlimited" filter, or at least a sort option by credit cost, so I can find cheap models without knowing the full catalog in advance.

3. Show running cost in the chat UI. A small indicator like "~$2.40 used this conversation" so I can see I'm about to blow through my balance mid-conversation, not after the fact.

4. Put the credit-to-dollar conversion in the account/settings page, not just the purchase screen.

I'm not asking for free unlimited Opus. I'm asking to be able to choose the cheap option without it being buried. Right now the default behavior is to spend credits fast, and the system doesn't warn you. That's a churn problem: I would not have renewed Pro if I'd known the real cost of a day of use.
