What it is

Upstage is a Korean AI company that builds the Solar family of large language models and a Document AI product line covering document parsing, OCR, and key-information extraction. Both are delivered as APIs through a self-serve developer console at console.upstage.ai. The console publishes English documentation, and the chat endpoints follow an OpenAI-compatible format, so existing client code can be pointed at Solar with minimal changes. The company also maintains a Korean-language official site and Korean-language guides alongside the English docs.

Who uses it in Korea

In Korea, the typical B2B use is processing Korean-language documents — parsing, OCR, and structured field extraction — and running Korean text tasks on Solar, since the models are built by a domestic lab with Korean handled natively rather than as an afterthought. We have not independently verified named enterprise customers in English-language sources, so specific client references are unknown.

For businesses entering Korea

For a foreign team, the practical draw is that this is Korean-native document and language AI reachable without a local intermediary: sign-up, API keys, and billing are all self-serve in the console, and payment from abroad is confirmed via prepaid credits with a standard credit card. English documentation exists for the model catalog and getting-started flow, which is not a given among Korean AI vendors.

What we verified

We confirmed the official site (https://www.upstage.ai/), English developer docs for the model catalog (https://console.upstage.ai/docs/models) and getting started (https://console.upstage.ai/docs/getting-started), and self-serve prepaid-credit billing in the official console (console.upstage.ai/billing), all last checked 2026-07-04. Korean-language support is evidenced by the official Korean site and Korean guides (https://www.upstage.ai/blog/ko/guide-1-upstage-console-api). Independent English-language reviews of the product were not found; customer names and deployment scale are unknown.
