Excited to release Grok 4.5 with @SpaceXAI.

It's an Opus-class model that's fast and low cost. It's a significant step up over any model we've developed so far, including Composer 2.5, and has become the daily driver for many on our team.

First of many releases. More soon.

[Elon Musk @elonmusk]

Grok 4.5, based on our 1.5T V9 foundation model, with Cursor data added in supplemental training, is now in private beta at SpaceX & Tesla. Early evals show performance close to, perhaps exceeding Opus.

RL is continuing to significantly improve the model, and the Grok Build harness gets better every day.

Nice work by all those involved!

Completely trained from scratch new models will be released by @SpaceX every month this year.

[SpaceX @SpaceX]

SpaceX has exercised the option to acquire @cursor_ai in an all-stock transaction with the goal of building the world’s most useful AI models.

For the past few months, SpaceXAI has been jointly training a model with Cursor, which will be released in Cursor and Grok Build soon.

We look forward to working closely with the Cursor team to advance our frontier AI capabilities

[SpaceXAI @SpaceXAI]

An early beta of Grok Build, an agentic CLI for coding, building apps, and automating workflows is now available for SuperGrok Heavy subscribers.

Through this early beta, we will improve the model and product based on your feedback.

Introducing Grok Voice Think Fast 1.0

A state-of-the-art voice model built for complex, multi-step workflows with snappy responses and high accuracy.

It takes the top spot on the Tau Voice Bench and handles real-world messiness like noise, accents, and interruptions better than any other model in the world.

[SpaceX @SpaceX]

SpaceXAI and @cursor_ai are now working closely together to create the world’s best coding and knowledge work AI.

The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will allow us to build the world’s most useful models.

Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together.

Grok Voice Agent API is now one of the most advanced voice AIs in the world

It ranks #1 on BigBench Audio for speech reasoning

Grok Voice already powers voice mode across Grok apps and runs in millions of Tesla vehicles

Conversations feel so natural, expressive, fluid, and instantly responsive - like talking to a real person, not a machine

Try it now on Grok, in Tesla, and across the growing ecosystem of apps and experiences powered by xAI

Congrats to the @xAI team and thank you to investors for your faith in our company
