What you can open

Lab card and OpenRouter listing only. No Hugging Face Files button, because there is no official repo to point at.

Fetched OpenRouter catalog on 2026-08-19. hugging_face_id was empty.

Continuum serving

Not listed as a Continuum hosted id. First-party Upstage API or OpenRouter upstage/solar-pro-3.

Continuum hosted id not on the host list

We list first-party and OpenRouter, plus Continuum only when the live public allowlist named the id. This is not a 15-host routing table.

FAQ

Is this Solar Pro 3.0?

upstage/solar-pro-3.0 is not in the 19 Aug catalog. The live slug is upstage/solar-pro-3.

Can I use Pro 4’s $0.03 promo here?

No. That window is on the Solar Pro 4 card. Pro 3’s catalog pair is $0.15 / $0.60.

Why does the lab blog disagree with DeepSWE or Scale?

Lab posts pick a harness, an effort, a split, and sometimes a private eval set. DeepSWE publishes the official mini-swe-agent row with cost, tokens, and steps. Scale SWE-bench Pro only counts when the public shared-harness board has a row we can fetch. A higher lab number is usually a different test, not a better one.

OpenAI-compatible call

No Continuum hosted id is verified for this model, so this page does not invent a curl target. Use the first-party API or the OpenRouter slug upstage/solar-pro-3.
