Why this status

Newly added. Sources are not archived and no value has been traced to one yet — run `npm run enrich`. Downgraded: context_window comes from the lab's documentation, but attribute-facts could not read an archived snapshot that states it, so the figure is not yet traced to a quoted sentence. reconcile-status upgrades it once attribute-facts succeeds.

What these states mean · How records are judged · Has this record changed?

Google launched Gemini 3.8 Flash Cyber, which it calls its most advanced cyber model, through the Fairwind Program — a limited-access programme for governments and trusted partners — paired with its CodeMender harness to find, verify and fix vulnerabilities. It is not generally available and does not appear in the public Gemini API model list.

Current information, elsewhere

This record is a historical one: every figure above is traced to a dated primary source. For what is true today — live pricing, current rankings, availability — these are better maintained than anything here could be.
