Grok 4.5 is worth trying

[X Freeze @XFreeze]

Grok 4.5 just ranked #2 on the FrontierSWE leaderboard, outperforming Claude Opus 4.8 and GPT-5.5

It delivers top-tier coding performance with exceptional speed, strong token efficiency and a much lower cost than many competing frontier models

Grok 4.5 is already one of the best coding models available today, sitting at the very top

[DogeDesigner @cb_doge]

BREAKING: The new Starlink V5 is 48% smaller and 62% lighter than V4.

• Size: 384 × 306 mm vs 594 × 383 mm
• Weight: 1.1 kg vs 2.9 kg
• Power: 35–50W vs 75–100W
• Wind rating: 265 km/h vs 96+ km/h
• Same 110° field of view
• Speeds up to 375+ Mbps

Order the Starlink V5 terminal!

[Starlink @Starlink]

The next generation Starlink Kit is designed to deliver reliable, high-speed home internet. Starlink V5 has a smaller form factor and lightweight design with greater power efficiency than the Starlink V4.

With speeds up to 375+ Mbps, Starlink V5 delivers seamless connectivity for streaming, video calling, gaming and more.

Currently available in select areas. As production ramps, Starlink V5 will be available in additional areas.

People may disagree on which frontier model is best, but they all seem to agree the current X algorithm is superb.

SpaceX just launched two Falcon 9 rockets carrying 56 Starlink satellites in less than eight hours

SpaceX is moving at light speed right now

First:
• 27 Starlink satellites from Vandenberg

Then, just 7 hours and 42 minutes later:
• 29 more Starlink satellites from Florida

Two coasts, two rockets, 56 satellites, less than eight hours

For most space programs, one launch is a major national achievement
SpaceX launched twice in one day and was already preparing for the next mission

SpaceX is basically running an orbital assembly line

True

[Alice Smith @TheAliceSmith]

We could have closed borders and a welfare state.

Or we could have open borders and no welfare state.

But of course we’ve chosen the most foolish and destructive option available - open borders and a welfare state.

The worst of all possible worlds.

Falcon 9 launches 27 @Starlink satellites from California

[Farzad 🇺🇸 🇮🇷 @farzyness]

Grok is the Flow LLM.

Grok 4.5’s biggest advantage is its speed.

It’s smart enough to be comparable to the other models on most things.

But that speed allows you to make little tweaks to your system so that the output is PERFECT.

With the other models, it takes FOREVER to do this, and you constantly end up outside of a flow state, which makes it way way way harder to do this.

It’s now my preferred model.

Starlink will provide high-speed, low-latency connectivity onboard @FlyFrontier, transforming every flight into a fully connected experience 🛰️✈️

Right-wing wave in Europe.

France 🇫🇷: Marine Le Pen now leading polls to be next President.

Austria 🇦🇹: the Freedom Party is leading the polls massively at almost 40%

Germany 🇩🇪: The AfD party now consistently number ONE in polls.

Norway 🇳🇴: The Libertarian FrP party leading the polls by a wide margin.

Something is changing in Europe.

Grok 4.5 reaches #1 position on Long-Horizon Terminal-Bench

[tetsuo @tetsuoai]

The Long-Horizon Terminal-Bench paper landed around May and concluded that the results showed headroom for improvement. The best of the 15 models they tested finished seven of the 46 tasks, and the mean across all models was about two. That ceiling is what fifth place looks like on the current board.

Grok 4.5 is now at 13, and Fable 5 is at 12. A single task costs around 9.9M tokens, 231 episodes, and 85 minutes of wall clock time. That means agents are holding a plan across all of it and finishing, and that capability nearly doubled in two months.

SpaceXAI is on top, and they marketed the 4.2x output token efficiency, which undersells it. Two dollars in, six out, per million. On a benchmark where one task burns ten million tokens, the bill is dominated by input replay, and they say Grok 4.5 solves tasks in under half the number of steps, so there is less accumulated context to resend on every call. The efficiency compounds on the input side, which is the side that costs money.

Fable 5 is one task behind. Their own launch chart has them losing DeepSWE 1.1 to Fable by 17 points, and Grok 4.20 sits on this same board at 0.080 with zero completions, so whatever happened in 4.5 is not a family trait.

My read is that the 4.5 jump came out of training alongside Cursor, which is a stream of real agentic edit trajectories nobody else has at that volume, and nothing in the counterevidence argues against it compounding into the next checkpoint.

[Kevin Bass @kevinnbass]

Just a reminder that deepseek v3 came out 18 months ago and was considered revolutionary at the time but is basically unusable today

There was a fierce debate at the time about vibe coding and the argument was that LLMs can never create anything new because they are limited by their training data

Those engineers were partly right and vibe coding was a real nightmare, I cannot believe what we used to put ourselves through with Sonnet 3.5, but we also knew real new things could be made and that the detractors were wrong

I guess us non-engineers saw it most clearly (I would like to think so at least) because we were astonished at the new things we could do without the programming background, and we had nothing to lose and everything to gain in our enthusiasm

Then came Opus 4.5 earlier this year which changed everything

Suddenly real production code became possible with so much less friction and headache

Everyone complained endlessly about models being nerfed or quantized but there was a steady march of progress from 4.5 to 4.8

Now a completely new crop of models is coming out that is not quite a 4.5 moment but something close

We are not only getting more polish but things are becoming a little freaky, entire isolated domains become possible to combine with small teams or even just one person into new applications that would have required large infusions of time and capital in the past

My wife back in 2021 told me about AI but I was in healthcare, I thought she was being a little nutty, and she talked like something from a science fiction film was coming and she got involved in it early on

She never stops letting me know that she was right, and she was

The next year is going to be wild, the world is truly going to change over the next few years, the scale of disruption will be a combination of astonishing and awesome, but also catastrophic

There are many amazing things ahead and extraordinary challenges and opportunities

We are living inside one of one of the biggest revolutions in human history

The woke mob had turned Twitter into Wormtongue to the World

[Arthur MacWaters @ArthurMacwaters]

Elon buying Twitter and restoring free speech was unironically one of the most pivotal moments in the 21st century

Its effects will be studied for generations

[X Freeze @XFreeze]

SpaceX was founded on one powerful belief:

A future where humanity is out exploring the stars is fundamentally more exciting than one where we are not

Every Falcon launch, every Starship test, and every step toward Mars is built around that belief

The goal is not just to reach space

It is to build a future where humanity becomes a multiplanetary civilization

[tetsuo @tetsuoai]

Crazy what you can build with Grok 4.5 and Grok Build in minutes.

[Jason Ginsberg @JasonBud]

@just_cameron The default in Grok Build is off. You can also run /privacy and any synced data is deleted. ZDR is respected for both headless and interactive use as well.
