Published rows are visible, but no category has enough eligible evidence for a comparative rank.
11 published rows leave some tracked benchmark slots empty.
Each value carries a field reference instead of floating alone. Markers compare this model with the current ranked and priced catalog; they are not absolute quality thresholds.

Coverage is split by category so a strong number never hides a thin evidence base. Verified means the row is tied to a published source; provisional rows remain visible but separate.
Each documented value carries its source. Missing fields stay visible as not sourced or not published, rather than disappearing from the page.
Scores and ranks appear only where published evidence can be displayed. The table keeps the score, weight, cohort, and evidence state together.

The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track Solar Pro 4, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.
Solar Pro 4 is a proprietary model with a 512K context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.
Available through the Upstage Console API as solar-pro4 with a 512K context window and 128K maximum output, text in and text out. Upstage ran a launch discount through September 10, 2026 and a 70% promotion through October 10, 2026.
Solar Pro 4 sits in the Solar family with Solar Pro 2, Solar Pro 3. Its explicit predecessor is Solar Pro 3. 11 of 434 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.

Solar Pro 4 has 11 source-displayable benchmark rows, but it does not qualify for a public overall rank. The available rows remain visible by category without being converted into a site-wide score. Missing evidence stays blank instead of being estimated from an earlier model.
Solar Pro 4 has source-displayable benchmark coverage for knowledge and understanding, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Solar Pro 4 has source-displayable benchmark coverage for coding and programming, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Solar Pro 4 has source-displayable benchmark coverage for mathematics, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Solar Pro 4 has source-displayable benchmark coverage for agentic tool use and computer tasks, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Solar Pro 4 has 1 source-displayable Korean benchmark score on this profile. Those rows remain separate from the global overall score because regional evaluations use a different comparison set. Use the dedicated Korean tables for side-by-side positions and inspect each source before applying the result elsewhere.
Solar Pro 4 belongs to the Solar family. Related tracked variants include Solar Pro 2, Solar Pro 3. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
No. Solar Pro 4 currently has 22 source-displayable rows across 434 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
Solar Pro 4 has a documented context window of 512K. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
