When not to use it

Trust this before you buy

  • When you need a Continuum-hosted SKU from this lab, use the hosted card on this hub instead of this catalog row.
  • $1.25 in / $10.00 out per 1M on the 2026-08-19 OpenRouter row. Context 400,000 in / 128,000 out.
  • Need a denser published sibling on this hub? GPT-5.6 Luna is the card already on the cluster.

Plus is $25/mo with $25 weekly hosted usage. The Mac app stays free with your own keys. Get Plus is not Download for Mac.

Artifact

Weights

Closed API SKU. The 2026-08-19 OpenRouter row lists pricing and context; there is no official Hugging Face weight dump on that row.

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.

05

Continuum serving

OpenRouter slug openai/gpt-5 on the 2026-08-19 catalog.

First party: https://platform.openai.com/docs/models.

Not on the Continuum host list fetched 2026-08-19.

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

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 openai/gpt-5.
