What Ultramarine 1 Flash is
Paper Instruments published Ultramarine 1 Flash on October 14, 2026. It is built on GLM-5.3 Flash, an open model. According to Paper Instruments:
- It was trained for finance, law, consulting and operations.
- It delivers spreadsheets, slide decks and Word or PDF files.
- In Paper Instruments' own internal test, each task cost a fraction of what it cost with the closed models it compared.
Who it is for
- Office teams that build reports, spreadsheets and slide decks every week.
How we deploy
Today there are no weights to download. Leave your case: when Paper Instruments publishes the weights under a license that allows commercial use, we test with your tasks and deploy.
How it works
You describe the case
The tasks, the files and the volume.
We test with your samples
When the weights come out, we test with your tasks, including the quality in Brazilian Portuguese.
We connect it to your access
The model joins the API you already use, connected to your key.
Good to know
- The weights and the license are not published yet, and the page does not say when they come out.
- The cost and quality test is Paper Instruments' own, with an automatic grader.
- It does not read images: Paper Instruments did not train it with vision.
- On-demand deployment: the model goes live when an organization asks for it.
