xAI API

Developer API

Product xAI API is SpaceXAI’s developer API — not a work product. A model being available in the API says nothing about whether it can be used in a work assistant.

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.

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.

No capability on record. That does not mean the product has none.

What does it connect to?

Systems this product can work with. Recorded from sourced updates; unlike model availability, they are not re-checked against the provider’s pages.

No integration on record. That does not mean the product has none.

How the model line-up changed

Every recorded interval, per product and scope. The current one shows whether a source check confirms it.
