Lumen
Lumen has been updated, please send email to help@ncsa.illinois.edu with subject Lumen if you have questions. Certain models will need to be acknowledged before use (one time only).

Models

The Models page (/models) shows every AI model available in your Lumen instance, along with its pricing and current health.

Models dashboard

Table Columns

Column Description
Model Clickable name — links to the model detail page
Coins / 1M tokens (input) Cost per million input tokens
Coins / 1M tokens (output) Cost per million output tokens
Total Endpoints Number of backend servers (underlying servers providing the model) configured for this model
Healthy How many of those servers are currently reachable
Last Checked When the most recent health check ran
Status Current availability (see below)

Status Badges

Badge Meaning
ok (green) All backends are healthy — model is fully available
degraded (yellow) Some backends are down, but at least one is working
down (red) No backends are reachable — model is temporarily unavailable
disabled (gray) Model has been turned off
no endpoints (gray) No backends have been set up for this model

Understanding Pricing

Coins are Lumen's internal currency. See the Introduction for a full explanation of how tokens and coins relate. The prices shown here are per million tokens — typical single messages cost a small fraction of that.

Models with higher output rates tend to be more capable or larger. If you are cost-sensitive, compare models on the detail page before running a long batch job.
