How this price is scoped: Upstage's own pricing page list price, per 1M tokens (input $0.15, cached input $0.015, output $0.60), which OpenRouter matches exactly. Upstage states that all prices shown are exclusive of 10% VAT, so a VAT-liable invoice runs 10% above the tracked rate. Third-party catalogue models.dev disagrees, listing this SKU at a flat $0.25 in and out; the vendor's own page is the source of record here. Solar Pro 2 is listed by Upstage at the same $0.15/$0.60. Upstage published Solar Pro 4 on 2026-08-11 (tracked as upstage-solar-pro-4) and Solar Pro 3 remains listed at this price alongside it; the earlier note here, that no 'Solar Pro 4' appeared on Upstage's own pricing page as of 2026-08-07, was true when written and is superseded by that launch. Upstage's pricing page moved to /pricing/api — the bare /pricing URL cited here previously now 404s.
Price receipt
Historical price.This model is retired — withdrawn on — so the provider no longer sells it and its page can no longer confirm this number: a price for a model no longer on sale is unconfirmable by definition, not missing. The figures above are the last prices we recorded for this model, kept as a historical record rather than a live quote.
Overview
Retired: Upstage ended service for Solar Pro 3 on 2026-10-30 (KST), 2026-10-29 15:00 UTC; requests to it now fail. A 102B-parameter mixture-of-experts model activating 12B parameters per token, last priced at $0.15/$0.60 per 1M tokens. Use Solar Pro 4 instead.
Capabilities
struck through = not supportedBenchmark performance
accuracy % · higher is betterWe hold no per-benchmark accuracy scores for this model yet, so it has no accuracy average. That is a gap in our coverage, not a sign the model is untested — independent evaluators often publish a composite index for a new model long before releasing its per-benchmark numbers. The percentile above is its standing across the independent composites below.
- AA Intelligence Index: 7.8 (Artificial Analysis composite across reasoning, knowledge and coding evals)
- AA-Omniscience Index: -53.7 (−100–100)
- GDPval-AA v2: 272 ELO (Real-world work tasks, human baseline = 1000)
- Ranks #174 of 194 comparably-measured models by percentile score, across 3 independent measurements
- Ranks #85 of 194 comparably-tested models by normalized performance per dollar
