Priority Tier - GPT-4.1 / GPT-4.1-mini - does it exist?

gpt-4.1-mini does exist as a “priority” model, and you can also get a zero bill if enrolled in complementary daily tokens. The notable exception without priority service tier is gpt-5.4-nano.

Lots of zero billings if you click “other” on the legend of Usage.

The peculiar thing I note: despite a $0 total for “priority | gpt-4_1-mini”, it appears with its own graph, indicating it was called (models not used will not be shown), but with no data. This is a fairly useless UI, and what can be considered the confusing issue, bringing about this forum posting.

The fault is:

• usage → spend categories
• see tons of models appearing despite no dollar bill
• the graph is there if you hover, to see also a daily $0
