Minor changes to the name, such as using "Grok 4-reasoning" or "Grok 4-beta" instead of "Grok 4", are acceptable when determining the release.

To count as released, the model must be publicly accessible. waitlist signups where only a portion of the general public has access by some date is sufficient for a YES resolution.

If it is available through some API only this counts as a release.
