Graded C+ on resilience. In Vannus's assessment it has not disclosed which model it runs — acceptable, with limits worth knowing.
South Korean enterprise AI company offering the Solar LLM family (Solar Pro 3, Solar Pro 2, Solar Mini), Document AI (Document Parse for converting complex documents to machine-readable form, Information Extract for pulling structured data from invoices, claims and contracts) and Studio for building and deploying document-workflow agents. Deployment is offered via REST API console, AWS Marketplace
Not disclosed. Upstage does not publish which model it runs, so this criterion is excluded and the grade rests on what we could verify. We say so rather than guess.
This is a separate question from the grade above. The grade measures resilience — whether the tool endures and whether you could leave it. This measures who can compel your data. A tool can score modestly on one and strongly on the other, and many do.
The vendor's published or catalog-recorded posture — the concrete facts this grade is built from. A full audit verifies each against the vendor's current documentation.
Vannus grades Upstage against nine dimensions of trust — data sovereignty, training privacy, compliance posture, operational resilience, exit portability, and more. The heaviest criterion asks whether the tool builds its own AI or resells someone else's model; where the vendor discloses it, the grade cites the vendor's own documentation. No paid placements — scoring is walled off from affiliate revenue. See the methodology →
