Which models does it offer?
The models confirmed in this product, by status. A model in a product is the model plus the product around it — results from elsewhere do not carry over automatically.
This is not a complete plan line-up. A plan or surface without a row means unknown, not unavailable.

“Not verified” means on record without a source check — it does not mean unavailable.
Where a start is “not documented”, a source check found the state in place; the source names no start date.
What does it add beyond the model?
Capabilities of the product itself — tools, agents, memory. Recorded from sourced updates; unlike model availability, they are not re-checked against the provider’s pages.
