Upstage

Upstage is an LLM and document AI platform from Seoul: the Solar model API, Document Parse and Studio agents on one account, paid by usage or per seat.

Upstage gives companies one place to read their documents and reason over what they contain. Upstage Co., Ltd., a Seoul AI company led by chief executive Sunghun Kim, builds and runs it. Every part sits on one account, so credits bought for the API also pay for work in Studio. The platform is aimed at document-heavy work in insurance, finance, healthcare and manufacturing. Solar Pro 4 is the flagship language model, with tool calling, strict JSON schema responses and a reasoning setting that trades speed for harder thinking. Solar Mini 4 takes high-frequency, cost-sensitive requests, Syn Pro serves Japanese business work, and Embed 2 turns text into vectors for search. Document Parse converts PDFs, scans, spreadsheets and slides into HTML or Markdown that a model can read. Information Extract pulls key-value data from invoices, claims and contracts without templates, while Document OCR and Document Classify handle plain text recognition and sorting. Upstage Studio runs agents that check invoices against contracts, stop duplicate claims and assemble underwriting files. Developers building document pipelines, retrieval systems or agents on top of a model are the Console's audience. Operations teams in claims, lending, KYC, revenue cycle and accounts payable use Studio when they would rather run agents than write code. The API is paid by usage, per token or per page, and teams that prepay a monthly or yearly commitment receive bonus credits, higher rate limits and faster support. Studio is sold per seat, starting with a no-cost plan, and larger organisations sign an enterprise contract with custom limits, connectors and on-premises deployment. A typical deployment parses a stack of loan or claim files with Document Parse, extracts the fields a reviewer needs and asks Solar to reason over the result. Teams on AWS can buy it through AWS Marketplace and run it in Amazon SageMaker, and developers can reach it from OpenAI Codex CLI or through an MCP server. Data that must stay in Korea can go to a Korean regional endpoint, currently in closed beta. Schools, hospitals and nonprofits can apply for no-cost access to Solar Pro and Document Parse. Upstage fits organisations whose decisions depend on documents being read in full and checked against each other.
