Flagship model for demanding analysis, coding, and production agent workflows
Solar Pro 3 by upstage is offered by 5 providers on this page. Its official list price is $0.25 per 1M tokens. The lowest paid channel is Upstage at $0.25 / $0.25 per 1M, about 1.7× below the list price.
Artificial Analysis rates it 7.8 on the Intelligence Index, with 16.2 for coding and 1.4 for agentic tasks. Against its lowest blended price of $0.25 per 1M, that is roughly 31 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 139 tokens per second, with 1.26s to the first token. Running one task of the Artificial Analysis suite costs about $0.0794, which reflects how many tokens its reasoning consumes rather than the unit price alone.
The context window is 131,072 tokens, with an output limit of 8,192 tokens. It supports reasoning, tool use, and structured output. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use. Its training knowledge cuts off at 2025-03.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

Sorted by blended price (input×0.75 + output×0.25) asc. The official channel always shows regardless of rank. Whether a gateway's low price is actually usable can't be verified.
Price history accumulates from each data sync; currently only 1 sample(s) (2026-08-17). Each future sync adds a point, and once accumulated a line is drawn here.
Individual evaluations run by Artificial Analysis, on the same reasoning tier as the intelligence score above. Each benchmark has its own task set and harness, so rows are not comparable with one another. The Intelligence Index above draws on a different, newer set of evaluations.
