Software @Tesla, opinions my own

@tomasscssantos Its the feeling right before this, where you think that the challenge is so insurmountable, you yourself question if you're capable, then when you finally solve the problem, you're reminded why you should never give up while riding the high.

Best Grok 4.6 advertisement I've seen this year

[Felix Rieseberg @felixrieseberg]

Today, we're releasing Fable 5.1 and Mythos 5.1. While the model is getting slightly better at a lot of things, I expect many users to appreciate that Fable 5.1 solves agentic coding tasks at roughly half the cost of Fable 5.

I personally also really like it's writing style, which imho sounds a lot more natural then our previous models did.

Some other personal highlights below!

I no longer use Claude models because the speed + intelligence of grok, when leveraged with appropriate prompting / skills have continued to out perform my Claude experiences. This is across long horizon engineering, embedded c, tests, build infra. Not to mention i save money!!

[Elon Musk @elonmusk]

@TheChiefNerd Worth trying Grok 4.6. Fable 5 is smarter overall, but Grok is much faster and lower cost.

Grok 4.7 has a good chance of exceeding all current models in intelligence.

[Cursor @cursor_ai]

Cursor is now part of @SpaceX.

Today, we have officially closed our acquisition. We will join the @SpaceXAI team to help make Grok the world's most useful AI and improve Grok Build, Grok Bot, Grok API, Cursor, and more.

SpaceX has built some of the most inspiring and impressive technology in the world, and we’re grateful for the opportunity to become part of such a special company. Onwards.

@ThomasAlxDmy 😂 I have to try this

[Sammy @SammyMacaluso]

@elonmusk It’s actually way cooler from this angle..wow

[Austen Allred @Austen]

Grok is now very underhyped.

A few folks at Gauntlet AI are now using it as their main/daily driver. Over Fable/Sol.

Folks who I wouldn’t have predicted would touch a Grok model with a ten foot pole even a few months ago.

Cool news from Giga Texas

[Sammy @SammyMacaluso]

This model has become my new daily driver for real world engineering, its remarkably fast at an extremely low price! HIGHLY Recommend you give it a try. Congrats to the SpaceXAI Team!

Grok 4.5 is built for real-world engineering. It excels in large codebases and handles long-running tasks that span multiple repositories, hundreds of skills, and a variety of tools.

[Tomas Santos @tomasscssantos]

@RoKhanna Wy don't you focus on cutting costs instead. we don't trust gov with our money because you spend recklessly and inefficiently.

[Sammy @SammyMacaluso]

So excited to see this vehicle launch in North America! Thank you to all of the Tesla teams who made it happen!

[Sammy @SammyMacaluso]

This team is stacked! Exciting times 💪 this model paired with grok build makes me hopeful for the future! This is only the beginning!! @aksheyd @milichab @JasonBud

[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.

Just took delivery of the 59k @cybertruck !

Nice to have cloth seats again and they look great.

More to come on drive quality. Previous truck was an F-150.
