“@SpaceXAI will make Grok 4.5 available to the public tomorrow. It is an Opus-class model, but faster, more token-efficient and lower cost.”

The fine print
Posted July 8 2026 (~06:21 GMT). '@SpaceXAI' is xAI's account. 'Tomorrow' from a July 8 statement = July 9 2026 — a one-day public-release promise. Watch x.ai/grok.com for the public rollout; any public availability (even tiered) = delivered per L13.

On July 8, 2026 Musk said xAI (posting as @SpaceXAI) would make Grok 4.5 available to the public the next day, July 9, describing it as an 'Opus-class' model that is faster, more token-efficient and lower cost than the prior generation. The claim followed a customer beta-test program. It is a near-term, one-day release promise that resolves as soon as Grok 4.5 is publicly available.
