Composer 2.5 is now available inside Grok Build.

Composer 2.5 is a fast, highly intelligent model that excels on long-running tasks and following complex instructions.

Grok Build 0.2.7 is now out, with /usage, /login, shared terminals across subagents, and improved image understanding

Grok foundation model V9-Medium (1.5T) has finished training. Evals look good. A lot of Cursor data was added in supplementary training and there is more to come.

Fine-tuning is underway and reinforcement learning begins in a few days. 2 to 3 weeks to public release.

This will be a major improvement over the 0.5T v8-small that currently serves all Grok production traffic, especially for difficult coding tasks.

SpaceX is actively hiring world-class engineers/physicists for SpaceXAI, even if you have zero prior experience in AI. Smart humans figure it out fast.

Please send an email with ~3 bullet points demonstrating evidence of exceptional ability to [email protected].

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.

@stepango @X I find as we improve the X recommendation algorithm with Grok my for you is better at finding accounts I like more than myself.

@stepango @X @xai Same

[Elon Musk @elonmusk]

@mark_k We have many great Grok models training simultaneously in Colossus 2.

I am confident that they will bear fruit.

And work on the Grok Built harness is progressing well.

[CS2 @CounterStrike]

Welc☢️me back.

[Bryan Cortez @ItsBryanFam]

@Unyshek Yes to both 👀

What are you doing next week?

[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.

[Shen Zhuoran @CMS_Flash]

Cool work of the team is finally out in the world.

This is a very early preview, and much more is to come around:

- One-shotting complex web apps;
- Pure vibe coding;
- Self-improvement between browser use and web app development.

The last point is critical and unique to web dev, because there is an intelligence gap between using a web app and building a web app that we can exploit, in theory leading to indefinite scaling of self-improvement.

Grok's Speech to Text API is now available.

Instant, multi-speaker transcription across 25 languages - at the best price in the market.

We are taking another small step today towards making Grok truly useful.

For him to succeed he must exist in an environment where success is in the set of possible outcomes.

The team is working to provide him access to same tools, context, and signals that we have in our lives.
