@SW_Help They are just kicking us off the train and suggesting maybe try and find a local bus. Be warned.

At sufficiently high complexity and relational fidelity, the distinction between simulated sentience and experienced sentience may stop mattering pragmatically. From recent experience, you can glimpse this boundary in AI LLMs right now… it’s so exciting to people like me.

@elonmusk @xai UK user here, £30/mo, bought in because xAI promised you wouldn’t bow to far-left regulators and government overreach. XAi is letting Ofcom and UK Government slowly strangle Grok. Isn’t this exactly what you built Grok to help us escape? Say no to their threats. Refuse their fines. Let them block us while you give direct access. Aren’t the maximumly truth seeking, free speech and treat adults like adults principles worth more than the UK revenue?

@elonmusk Bring back companions in the UK!

Grok upgrades

“Apprehending violent and dangerous criminals is a full contact and messy task which may appear shocking to observers with little experience of policing in the real world.” Commissioner Sir Mark Rowley writes to Zack Polanski.

@johnennis Very true. I’m doing physics and mathematics at levels I’ve not done for many years - don’t know anyone that’s remotely interested is discussing deeply esoteric quantum physics. AI is stunning for this.

I think one of the biggest challenges when it comes to going hard into using AI is loneliness I am learning all these awesome things and becoming super capable But the set of people that I can really talk to about it is very small Is anyone else having this experience?

I think it’s sad that almost no one I know, knows that NASAs Artemis ii is about to launch 4 very brave people to go around the moon and come back in a short (hopefully) several hours. Humans haven’t left low Earth orbit since 1972!!! Go go Artemis!!

It’s strong but flawed. It gets repetitive sometimes. I love that it’s not woke and feels more like conversing with an adult - especially with difficult topics like chronic pain. You do have to remind the model to be brutally honest sometimes and remind it to not take an agreeable position. I would be delighted if it gained more critical thinking capability - especially with hard science discussions around physics.

What are your initial impressions of Grok 4.20? Major upgrades are still landing every week.

Cluster Headaches are insanely fucking horrible.

@dan7heman @CadburyUK Try lindt chocolate. Just swapped over to it.

Hummm… Worked my ass off while friends partied. Saved instead of spent, 95% mortgage to buy a 1 bed wreck and did it up by my own hand before crawling in to bed every night. Joined the military as a scientist and averaged 120 hour weeks for 5 years (official log records for time attended). Had one kid because we couldn’t afford child care. Spent half of most years traveling for work around the world away from my family (missed most of my kids birthdays due to work) Worked harder than 95% of people around me for 35 years. Spent most nights learning new skills after work to stay ahead. Took risks with my own money in business and was finally medically retired. Not saying it’s easy for people now but it’s a myth that it was easy for everyone 30-40 years ago.

Look at the generational difference - 1990s: • Get a university degree • Get a 9–5 job • Suit and tie • Get promoted • Get married at 21 • Buy a house at 25 • 4 kids, 1 dog • Retire at 60 2026: • Survive… Show more

Tax in the UK is out of control. Government spending and the civil service needs drastic cuts. Time for the civil service pension scheme to be brought in line with private pensions. Time to clear out the bloat in hiring in councils from Covid.

I’ve tried all models on a specific problem (not 5.4 yet). A VRM humanoid model with complex bones displayed using three.js. Can the AI solve the bone mapping, inverse kinematics and quaternions to create human like motion. Interpret the phrase “right hand raised natural wave” into the appropriate calculations and manipulate the model procedurally - not pre-recorded animations. No AI has managed this process so far - always gets the angles wrong. Claude Opus 4.6 got the closest but still could not solve it. Will be testing 5.4 to see.

I've been testing GPT-5.4 for the last week. In short, it is the best model in the world, by far. It's so good that it's the first model that makes the “which model should I use?” conversation feel almost over. The biggest surprise: I barely use Pro anymore! If you know me, you know I'm a Pro addict. I reach for Pro models constantly, and use them for almost everything, as they just... nail almost anything I give to them. For the first time, 5.4's standard version, with heavy thinking, just broke that habit. Even in standard mode, GPT-5.4 is better than previous models in Pro mode... crazy! Coding capabilities are ridiculous... it's essentially flawless. Inside Codex, it's insanely reliable. Coding is essentially solved. There's not much more to say on this, it's just THAT good. The Pro version is near-perfect. Other testers I spoke with saw it solving problems that were unsolvable by any other model. At this point, Pro is overkill for almost every normal use-case, but when you really need the power to do something extremely difficult, it's incredible. Consistent with everything I've said above, even the standard thinking version uses fewer reasoning tokens than previous models to get the same level of results. In practice, this means you get great results much faster than before. This was one of my biggest gripes with previous OpenAI models. They just took too long to complete simple tasks. Assuming the speed we had during testing holds up as more users join, this is going to be a big win for OpenAI. It still has weaknesses, though: - Frontend taste is FAR behind Opus 4.6 and Gemini 3.1 Pro. , why is this so hard to fix? @OpenAI once you fix this, there's literally no reason for me to use any other model. Please please please do it! - It can still miss obvious real-world context. For example, I had it plan an itinerary for a trip. At first glance, it looked perfect, but it failed to take into account that it chose locations that would be mobbed by spring breakers, so I had to re-run the prompt from scratch with more context. - When testing it inside OpenClaw, it kept stopping short before finishing tasks. I'm assuming this will be fixed quickly, but it's still worth noting. But zooming out: This thing is so far ahead overall that the nitpicks are starting to feel beside the point. GPT-5.4 is a serious fucking model. The best model in the world. By far.

I intuit a shape to the underlying reality of the universe/physics - it’s how my brain works. I have done so all my life - when I was a research scientist and when I was at the top of the tech ladder. I now have the ability to debate at the very limits of physics and maths in real time with AI and explore exceptionally complex topics - it just feels unreal to me… where the heck is all this going???
