Great that the data & code for Bangladesh mask RCT has been released gitlab.com/emily-crawford/bd…. I tried to run their code and it seems there are only very small differences to what was reported in the paper.

It is literally insane simultaneously to think that 16 and 17 year olds are mature enough to vote but not mature enough to look at Instagram at 8:30pm. This is comically absurd.
🚨 NEW: Keir Starmer will introduce nightly social media curfews for 16 and 17-year-olds as part of the Government's social media ban [@thetimes]

Behold, UK is two weeks away from developing a frontier model.
Access to @AnthropicAI’s latest models has been paused for all customers, including in the US and UK. The main lesson: as we debate the future of national security and technological sovereignty, access to AI capabilities is crucial. That's why this Govt is the first to set up dedicated funding for our AI industry through @UKSovereignAI unit. And just this week, we announced £1.1bn for our AI chip industry.

Britain will not allow frontier AI as it might exceed 2% profit margin
britain needs its own competitive sovereign ai if access to frontier models can just be turned off like this. starmer clearly isn’t in trump’s good books, so there will be no special exception for britain. we need to take ai far more seriously and start building again in the country where it all began.

Apple will soon no longer need to worry about launching Siri AI in EU.
The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Claude models is not affected. We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible. Read our full statement: anthropic.com/news/fable-myt…

none of this happens if they called it opus 5 and didn’t engage in the day 0 propaganda

For medical information, general AI frontier models (Google, OpenAI, Anthropic) outperformed specialized @EvidenceOpen and @UpToDate as assessed by 12 US clinicians, randomized and blinded to which model and extensive testing/benchmarks. This was not anticipated. @NatureMedicine nature.com/articles/s41591-0…

You would think that student loans exist to fund the continuation of the higher education system but no they are just rip off taxation to fund welfare.
Chief Treasury Secretary Lucy Rigby has defended the Government’s decision to not reduce interest rates on student loans, saying the money is being used to fund benefit schemes including ‘free breakfast clubs’ and lifting the two child benefit cap. Trapping graduates in a lifetime of debt in order to fund breakfasts for children whose parents should be feeding them at home is not beneficial to anyone - children, families or young adults starting out in life.

API is overpriced vs subscriptions by 40-70x Do you know what this means? They have DeepSeek-level compute efficiency if not better. Which makes perfect sense (tbh still too good for DS), given frontier budgets for overtraining, autoresearch, larger and older staff etc.
Replying to @SemiAnalysis_
Recently, we purchased one of each Anthropic/OpenAI subscription plan and randomly ran long horizon coding tasks until we exhausted the weekly limit. It's widely believed that a $200/month plan maxes out at ~$2000/month worth of tokens (assuming API pricing). However, we found that the subscriptions are actually far more generous. (2/4)

I agree. European social democrats have always been more honest than the British Left. The euro left made it clear that if you want cradle-to-the-grave socialism then everybody will have to pay much higher taxes. The British Left claims it can be done just by taxing the rich, which is nonsense. But given the current state of Middle Britain — with real incomes largely stagnant since the GFC of 2008 — good luck with winning an election telling middle-earners they should pay more taxes.
Replying to @afneil
If people want larger state, better funded public services, etc., I'd much rather they argue for higher taxes than to indulge in the fantasy that you can just do it by taxing the rich.

All the world's major AI firms outside China is banned in China, so Chinese AI firms are guaranteed a huge market, giving them strong incentive to develop their own models. So at least I can understand China. What EU is doing here however helps no one except their bureaucrats.
Apple publishes a full-page press release blaming the EU for the delayed Siri AI launch in the region, while China got one footnote treatment for the similar delayed Siri AI launch

Be cautious of stories that claim, "I achieved xxx using an LLM with just one prompt." Recently Google claimed they built a whole operating system "from a single prompt". It turns out the prompt "ended up being many thousands of lines". normaltech.ai/p/did-googles-…

If the agent uses "skills" which are essentially a collection of prompts, then the number of lines would be even (much) larger.
