About

Solar Mini is a pre‑trained large language model that delivers GPT‑3.5‑comparable responses with 2.5× faster inference while staying under 30 billion parameters. It achieved first place on the Hugging Face Open LLM Leaderboard in December 2023 by combining a 32‑layer Llama 2 architecture, initialized with high‑quality Mistral 7B weights, with an innovative “depth up‑scaling” (DUS) approach that deepens the model efficiently without adding complex modules. After DUS, continued pretraining restores and enhances performance, and instruction tuning in a QA format, especially for Korean, refines its ability to follow user prompts, while alignment tuning ensures its outputs meet human or advanced AI preferences. Solar Mini outperforms competitors such as Llama 2, Mistral 7B, Ko‑Alpaca, and KULLM across a variety of benchmarks, proving that compact size need not sacrifice capability.

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.
