Why it was chosen
Moving coding agents to the cloud while releasing a 128B model supports assessments of the cost and feasibility of self-hosted coding agents.

A model scores each item twice, independently, against one written standard, out of 100. An item is admitted only when the two scores add up to twice the threshold. The threshold is set per source tier.
