SpaceX is expanding public availability of its Grok 4.5 AI model following positive results from beta testing, according to reports citing posts by Elon Musk on SpaceX’s social media on X. One outlet reports that Musk says Grok 4.5 will become available to the public on Thursday, July 9, after strong beta feedback. The same reporting characterizes Grok 4.5 as “Opus-class,” while also describing it as faster and more token-efficient than prior versions. Another source similarly frames the move as an expansion of access after strong beta reception, attributing the update to Musk. Together, the coverage indicates that SpaceX is moving from beta availability to broader public access and that the company is positioning the release around performance and efficiency improvements. The sources do not provide additional technical specifications beyond the general descriptors, nor do they detail pricing, limitations, or which user tiers receive access first.
