The post is from @elonmusk and tags Grok Bot and SpaceX. It does not point to a docs page, a changelog entry, or a model card. The public Grok Bot changelog at x.ai/changelog/bot still listed v0.66.0, dated 2 October 2026, as the latest release when this brief was written.

Limits of this report

The post does not say which Grok Bot surfaces this applies to, whether users can pin a model, how routing is chosen, or when it starts. It does not name prices, rate limits, or data-handling terms for the third-party APIs. Only the statements in the source post are reported.
