About

Solar Pro 2 is Upstage’s latest frontier‑scale large language model, designed to power complex tasks and agent‑like workflows across domains such as finance, healthcare, and legal. Packaged in a compact 31 billion‑parameter architecture, it delivers top‑tier multilingual performance, especially in Korean, where it outperforms much larger models on benchmarks like Ko‑MMLU, Hae‑Rae, and Ko‑IFEval, while also excelling in English and Japanese. Beyond superior language understanding and generation, Solar Pro 2 offers next‑level intelligence through an advanced Reasoning Mode that significantly boosts multi‑step task accuracy on challenges ranging from general reasoning (MMLU, MMLU‑Pro, HumanEval) to complex mathematics (Math500, AIME) and software engineering (SWE‑Bench Agentless), achieving problem‑solving efficiency comparable to or exceeding that of models twice its size. Enhanced tool‑use capabilities enable the model to interact seamlessly with external APIs and data sources.

About

Solar Pro 4 is an agentic AI model built to carry real work to the finish: reading documents, running tools, producing deliverables, and stopping when the evidence runs out. It targets longer, more complex workloads that move across multiple documents, execute tasks in a terminal, and chain tool calls over many steps. The model supports a 512K context window with up to 128K output tokens, allowing agents to load contracts, reports, and data files into a single session without splitting them. It handles English, Korean, and Japanese for both input and output, while adjustable reasoning effort lets users choose deeper analysis or faster, real-time interaction. Solar Pro 4 is designed to stay accurate through long documents, multi-turn tool use, and terminal tasks, and to preserve values and conclusions across sequential deliverables such as Excel workbooks, reports, and slide decks.
