October 26, 2026 — source check
The official introduction provides selected conversation recordings and describes limited safety-researcher access. Download controls still display a coming-soon message. No public API reference or open-source license is linked from the introduction we checked.
What counts as an availability change?
We distinguish a new recording from a runnable model release. Download availability requires a real official artifact and instructions; API availability requires official integration documentation. A new marketing button alone is not sufficient.
How this record is maintained
This is a manually checked editorial record, not an automated release monitor. We record what changed, retain the verification date for unchanged claims, and change that date only after checking the source. The date above identifies the last source check; later changes may not be reflected here.
