Solar Mini 4 is Upstage's compact model: a 35B mixture-of-experts with only 3B parameters active per token and a 524K-token context. It is designed for agents where response speed and price matter most, writes fluent Korean alongside strong English and Japanese, and handles long inputs well for its size.

It accepts text input and returns text, and supports tool calling, structured JSON output and streaming. Reasoning can be switched on when a problem needs more thought and left off when speed matters. Solar Mini 4 is commonly used for fast agents, classification, extraction, multilingual chat in Korean, English and Japanese, and long-document processing on a budget. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.

Pricing is usage-based: $0.05 per million input tokens and $0.2 per million output tokens. There is no fixed monthly fee, and you pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
