Saturday was a good day for Boca Chica Beach.
985 volunteers came out for International Coastal Cleanup Day and removed 2,880 lbs of trash from our shoreline.
Thank you to @SpaceX, @TXAdoptABeach, and Cameron County, and to every friend, family member, and neighbor who came out to volunteer.
This is what community looks like. See you at the next one!

In just the last 90 days:
1. Grok 4.3 — barely top 10. “xAI is dead beyond compute leases.”
2. Grok 4.5 — massive comeback. “Maybe a chance. But Grok will never catch up to the frontier.”
3. Grok 4.6 — they’re frontier. “Still not top 3.”
4. Grok 4.7 — now top 3 in frontier coding, while being much cheaper & faster.
5. Grok 4.8 next month.....
The model machine is just starting up.
Grok will be the workhorse of the upcoming agentic era.

day 1 observations for grok 4.7
ignore the reports that say “it’s terrible” and the only thing they reference is a public benchmark. the same benchmarks told us opus 5 was better that fable - they are useless
also ignore the reports that compare models with 3d games - that’s not real work. it's made for attention on social media
i used grok 4.7 for a whole day as my firstmate, and it has been a really solid model with visible improvements over 4.5 (i'm ignoring 4.6 because 4.5 has been working better in my experience)
key differences with 4.7 -
1. it follows system prompt very, very closely
i noticed firstmate showing many new behaviors that i've never seen before, such as asking me to name specific red CI checks that i'm ok with bypassing, and refuse a simple "yolo" instruction
i traced it and it's indeed how i instructed it in firstmate's system prompt, but none of the other models followed it closely enough to make this behavior visible - grok 4.7 is the first to pick that up
there were a few other similar examples as well. so to me this is a clear behavioral difference
2. it's very "stable"
if you've used astra then you know what a "spiky" model is. it can have some genius moments but you occasionally also wonder "how could it be so dumb and doesn't get me". grok 4.7 is the opposite of that
throughout the whole day so far, i'll be honest i haven't get a "wow this is absolutely genius" moment yet, but grok 4.7 has been very steady with no big surprises. its behavior feels predictable, which does help it gain trust from me quickly
3. it's a conservative model
it doesn't like to take actions without asking, and would explicitly say so
this is a bit of a double edged sword, because it means i sometimes have to state the obvious "yes i do want that", but in hindsight a lot of those cases are indeed a bit ambiguous and i may not have preferred the model to just move forward without my confirmation
4. it's a bit slower and costs more than 4.5, visibly
turns are taking a bit longer and my quota is draining at a visibly faster pace. i haven't quantified exactly where this is coming from yet
so overall, i think it's showing some clearly different traits, and i mostly like the changes. i'm going to keep it as my primary firstmate and observe more
if you've been using it, what qualitative insights have you gathered from real usage so far?

Grok 4.7 just released and it's an EXCELLENT model
It was trained FOR Grok Bot
Meaning this is a fully agentic model trained to do your knowledge work better than you can
In this video I show you how to use Grok 4.7 and a Grok Bot workflow that will 10x your productivity:

Been testing Grok 4.7 for the past week or more. It’s been a great improvement over 4.6.
It worked for over 70 hours straight on a goal. Much better attention to detail.
The 500k context window really makes a difference imo. 4.7 much better at things like skill selection; workflows. Found it particularly good with pstack.
Didn’t have access to it in Grokbot, but I really wanted to test it there. Together it’s a great daily driver.

Tesla has for years openly invited other automakers to license FSD. None of them have accepted.
Blake Scholl 🛫@bscholl· 21 сент. 2026 г.Prediction: Tesla will keep FSD an in-house advantage for a couple years, and then once others start getting close will begin licensing it for other cars—just as they opened up the Supercharger network.

Grok 4.7 xHigh is now at the top with just ONE point away from Claude Fable 5.1 Max on Artificial Analysis’ AA-Briefcase benchmark
Claude Fable 5.1 Max — 59%
Grok 4.7 xHigh — 58%
Just a 1-point difference at the very top
And Grok is ahead of GPT-6 Astra, GPT-5.6, Gemini, Kimi, GLM and nearly every other frontier model on the benchmark

Grok 4.7 made this in blender.
I didn't tell it what to make but only that it should be something it can accomplish in 10 minutes or so.
Honestly not bad at all. Not bad at all.
Did they train Grok on blender?

I’ve been testing Grok 4.7… it’s a really great daily driver, and a huge step up over 4.6.
Definitely worth trying!

We put Grok 4.7 from @SpaceXAI to work on a $2 million insurance claim where one deductible error alone changes the calculation by $143,000.
In this Box Agent preview, @grok reconciles the claim against the policy and supporting records. It catches an $82,000 duplicate invoice and a missing $64,000 supplier credit. It also explains why the Business Income waiting period doesn’t apply to Extra Expense.
The result is a cited claims review for the adjuster, with final coverage and payment decisions left to the insurer.
