Pairwise benchmark snapshot · Aug 17, 2026noindex (thin pair)
This page compares DeepSeek R1 (DeepSeek) and Upstage: Solar Pro 3 (upstage) using the latest snapshots we have as of Aug 17, 2026. Upstage: Solar Pro 3 wins on output price at $0.6/1M. Upstage: Solar Pro 3 has the larger context window (131k tokens). Every cell below is a dated snapshot from a named public source — we do not invent missing scores, and we do not run SWE-bench ourselves.
upstage
Upstage: Solar Pro 3Auto-discovered from OpenRouter (upstage/solar-pro-3). Preview until a second source matches.
enable_reasoningReasoning models scale test-time compute by generating hidden chain-of-thought (CoT) tokens. These tokens are billed at standard output rates and directly expand latency (TTFT) in exchange for higher GPQA Diamond and SWE-bench Verified problem resolve rates.
Standard large-scale RL reasoning trace with self-correction.
