Overview

Upstage: Solar Pro 4 is a large language model API from Upstage, part of its Solar Pro model family. At $0.030 per million input tokens and $0.120 per million output tokens, it sits in the budget tier — among the cheaper options for high-throughput or cost-sensitive workloads. Output tokens cost about 4× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. A large 524K-token context window (≈786 pages of text) lets it take in whole books, large codebases, or lengthy transcripts in a single call. On Artificial Analysis's Intelligence Index it scores 42 (B grade), a useful proxy for its general reasoning strength relative to the other models tracked here. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
