Reading the live model catalog

Profiles appear here when the machine guard connects. Availability is never simulated.

Context is the configured input-plus-output ceiling. Cold-start times are typical loads measured on the lab; preparation is excluded from session time. Dual-Spark profiles span both machines; a single-Spark session runs one machine. Mac Studio profiles run on the M3 Ultra with 256 GB unified memory, independently of the Sparks.

A small test before a big investment.

Start with 15 minutes free, with no card required. Continue the same session for two more hours for $20.
