Decision reading
Solar Pro 3 is tracked, but not publicly ranked yet. The profile exposes 1 sourced benchmark rows and leaves unsupported fields blank until a published record exists.

Data as of September 10, 2026 · How the score is built

Strongest published evidence

Instruction Following ranks #35. A well-rounded choice across a range of tasks.

Validate before choosing

1 published rows leave some tracked benchmark slots empty. Independent runtime speed has not been measured.

Decision snapshot

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.

How much of this is verified

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.

How to read this profile

The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.

We track Solar Pro 3, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.

Solar Pro 3 is a proprietary model with a 128K 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-pro3 (a 102B-total, 12B-active MoE with a 131,072-token context), plus OpenRouter and other routers. Upstage lists it at $0.15 input and $0.60 output per million tokens.

Solar Pro 3 sits in the Solar family with Solar Pro 2, Solar Pro 4. Its explicit predecessor is Solar Pro 2. 1 of 434 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.

Its strongest eligible category is Instruction Following at #35. a well-rounded choice across a range of tasks.

Frequently asked questions

How does Solar Pro 3 perform overall in AI benchmarks?

Solar Pro 3 has 1 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.

Is Solar Pro 3 good for instruction following?

Solar Pro 3 ranks #35 out of 123 eligible models for instruction following, with a public category score of 87.1/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.

Which sibling models are related to Solar Pro 3?

Solar Pro 3 belongs to the Solar family. Related tracked variants include Solar Pro 2, Solar Pro 4. 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.

Does Solar Pro 3 have full benchmark coverage on BenchLM?

No. Solar Pro 3 currently has 13 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.

What is the context window size of Solar Pro 3?

Solar Pro 3 has a documented context window of 128K. 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.
