Based on strong positive feedback from customers in our beta test program, @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.

[Elon Musk @elonmusk]

Correct

[Elon Musk @elonmusk]

An inspiring vision of the future is needed

[Elon Musk @elonmusk]

Our internal assessment is that Grok 4.5 is roughly comparable to Opus 4.7, but much faster. The combination of capability, faster speed and lower cost is what makes it competitive.

We are closing the loop on real-world usefulness, not benchmarks. Hardcore engineers at Tesla & SpaceX find Grok 4.5 genuinely useful, which is what actually matters.

We will be releasing a new @CommunityNotes feature that sends you an 𝕏 Chat message if a post you interacted with is corrected

Artificial Analysis assessment

[Elon Musk @elonmusk]

Grok groks engineering.

Next month’s release will be another step-change improvement, as we close the loop on solving real-world engineering problems at Tesla, SpaceX, Neuralink and Boring Company.

[Elon Musk @elonmusk]

Grok will be able to call Imagine as a tool in agentic mode for image/video generation. As Imagine keeps improving, this will be amazing for game developers!

Grok 4.5 context window will upgrade to 1M probably by next week

[Elon Musk @elonmusk]

Grok 4.5 true usefulness is excellent
