Paper Instruments is offering Ultramarine 1 Flash through its API at $0.15 per million input tokens, $0.03 per million cached input tokens and $0.50 per million output tokens. The model is based on GLM-5.3 Flash and targets professional work involving documents, spreadsheets, presentations and business systems.

The company says Ultramarine generates 6.5% fewer tokens than its base across six benchmarks. It reports a cost of $0.13 per task on PI Knowledge Work, its internal evaluation of finance, law, consulting and operations tasks. Those tasks use individual scoring rubrics and run models in the same harness.
