Emvryx shows your usage in plain messages, right under the message box. There is a short-term amount for right now and a longer one for the week.
An E that fills like a tank shows how many messages you can send in one sitting. It refills by itself, steadily, so there is no waiting for a reset. From empty it is full again in about 8 hours.
A weekly total, shown as a percentage and about how many messages are left. It resets every Monday at 4 AM in your own time zone. A strip of seven days shows which days were busy.
A message is one question and a normal-length answer. Bigger models use more of your usage. On a Pro week (about 1,000,000 tokens), that comes to roughly:
The effort setting next to the model chooser changes both the answer and the cost.
Behind the scenes, everything is counted in tokens (small pieces of words). The text you send counts once, earlier chat the server already holds counts at a tenth, and what Emvryx writes counts once, then it is multiplied by the model’s weight (Ember 0.5, Flare 1, Equinox 2, Solstice 5, Apogee 10). Tap “See the numbers” in the Usage screen to see them.
