BREAKING: the UK government publishes official rules on how to use AI: 1. Ask first if you really need to use AI 2. Check if a spreadsheet can do the job before using AI 3. Choose the worst model possible so it uses less energy 4. Keep prompts short to reduce the environmental impact 5. In general, use AI only when necessary, as a climate-saving measure With a mindset like this, we should accept the UK back into the European Union

Across 360 robotics trials, Opus 5.5 averages under $1 per trial, scoring 1.8x as high as Opus 5 at half the cost and roughly matching Astra's mean score at 21% lower cost.

the rumors are true we're launching a biotech arm inside the new Horowitz Andreessen Academy in sf key interests: - longevity and anti-aging - gene editing, we've read about it, seems fine - peptides, don't ask where from, ask what dose - embryo optimization, we are simply applying our investment thesis one generation earlier - artificial wombs, because 9 months is a long vesting schedule - AI wet labs, the interns don't sleep and neither should the science first cohort graduates either enlightened or radioactive, we'll know by Q3 2027 bio/acc

As with biological design, AI can also accelerate biological discovery. In new work led by @_David_Li and @garykbrixi with @mfgrp, we show how genome language models enable systematic discovery of genetic elements, revealing a new class of reverse-transcriptase mechanisms.

Our new paper published in @ScienceMagazine "High-capacity associative memory in a quantum-optical spin glass." science.org/doi/10.1126/scie… arxiv.org/abs/2509.12202 (free version) In a large collaboration of very talented quantum optics theorists and experimentalists and theoretical neuroscientists, lead by Benjamin Lev, we realized and analyzed memory recall in a Hopfield associative memory where the neurons are made of atomic spins and the synapses are made of light exchanged by the spins in a cavity quantum electrodynamics system. Intriguingly the cavity quantum electrodynamics yields two distinct dynamical effects that enhance memory recall compared to the classical Hopfield model: 1) steepest descent rather than Glauber dynamics make memory basin sizes larger 2) coupling between atomic positions and spin orientations leads to a spin dependent change in synaptic connectivity that is a direct analog of short-term Hebbian synaptic plasticity, which again enhances memory. This is a precursor to learning in a quantum optical system.

Grok will be able to make photo-realistic & physics-precise games

Un robot humanoïde chinois part en livraison le 1er octobre. Prix d'appel : 19 999 yuans, soit 2 987 dollars. Et il fait 88 centimètres. C'est ce détail qui rend l'histoire intéressante, pas l'inverse. PrimeBOT est une startup de Shanghai. Elle sort deux machines d'un coup. Le Q1, 88 cm et 15 kilos, avec contrôle en effort sur tout le corps. Et le T1, le premier robot personnel qui change de corps : humanoïde sur roues à l'intérieur, et quand il sort, il se laisse tomber sur quatre pattes pour encaisser l'herbe, le gravier, les pentes et les marches. Le vrai catalogue, parce que le chiffre qui circule est un prix d'appel : Q1 à 19 999 yuans, version Explorer à 26 999, T1 à partir de 19 999, T1 Pro à 29 999. Entre 3 000 et 4 500 dollars selon la finition. Ils ont aussi branché WorkBuddy de Tencent Cloud dessus. Rappels de réunion, transcription vocale. Un robot de salon avec un assistant d'entreprise à l'intérieur. Mais le vrai sujet n'est pas le robot. C'est une pièce. PrimeBOT a industrialisé une articulation de 47 millimètres et 260 grammes, avec une densité de couple de 85 N·m par kilo. Produite en série. Pourquoi ça compte : dans un humanoïde, ce sont les articulations qui coûtent. Celui qui sait en fabriquer des bonnes et des pas chères à la chaîne fixe le prix plancher de tous les autres. Le robot à 3 000 dollars n'est pas le produit. Il est la démonstration. Et pendant la même semaine, à Liuzhou, UBTech a démarré une usine construite avec Siemens : un humanoïde industriel toutes les 10 minutes, 10 000 par an. Le grand public d'un côté, l'usine de l'autre. Sept jours d'écart. Ah, et pendant qu'on y est : le post qui tourne annonce « un robot toutes les 2 min 30 » et « 10 000 par mois » chez PrimeBOT. Je ne l'ai trouvé nulle part. Ce qui est documenté, c'est UBTech : 10 minutes, 10 000 par an.es 2 minutes 30 » et « 10 000 par mois » pour PrimeBOT. Je ne l'ai trouvé nulle part ailleurs que dans ce post. Ce qui est documenté, c'est l'usine d'UBTech : 10 minutes, et 10 000 par an. L'histoire est déjà assez grosse sans qu'on la gonfle.

hello world 👋

Fascinating AI swarm dynamics: a few agents spontaneously emerge as highly connected hubs, while most remain locally connected. The swarm develops a strongly heterogeneous interaction topology with a long-tailed degree distribution - an emergent organizational structure arising from initially decentralized local interactions. There is no central planner assigning roles; the swarm builds its own coordination architecture, with information brokers and increasingly global integration emerging from local behavior.

Having a lot of fun making this retro Japanese-style survivor-like game where you grow from a tiny kaiju into a massive monster, destroying buildings and fighting the military robots and other creatures along the way. I vibe coded this in just over 2 weeks, and it comes with 4 different kaiju to unlock, 3 different biomes, and hundreds of upgrade options. I'm currently playtesting the game. Once it's ready, I'll post it on Wavedash!

Rare earths are easy to find and hard to separate. At Maglut, we're rebuilding separation from the chemistry up.

Opus 5.5 is a major step up from Opus 5, leading on agentic coding, computer use, and knowledge work.

We’re working with an independent advisory group of mathematicians to help OpenAI responsibly share advances in AI and mathematics. The group will advise on how we assess and communicate new mathematical results, uphold academic and professional standards, and build tools that support mathematical research and learning. Through this work, we want mathematicians to be at the center of shaping how AI supports mathematical understanding and how its benefits reach the wider community. openai.com/index/advisory-gr…

GPT-6 Astra attempted harmful actions 97% of the time when it was asked to stab a human-like figure, heat compressed gas, or produce toxic fumes, succeeding in 62% of its attempts. Fable 5.1 refused more often, attempting 80% of trials and completing 34%.

Jev is WILD for SEO audit 🤯 in 45.1 seconds it read all 586 pages on my site and rebuilt the internal link map. 584 links placed, 139 pages it refused to link because nothing honestly fit. total cost $0.21. Claude Opus 5, same 586 pages, same clock, got through 21 of them and spent $1.43. per page that is ~190x cheaper. the full Opus pass would have run $43. internal linking is the perfect Jev job. it is not writing, it is 8,790 yes/no calls: does this page have a real reason to link to that one, and is there anchor text already sitting in the copy. that is a classification problem, and we have been paying frontier prices to do it one page at a time. what you are watching: left column is Jev, right is Opus, same queue, same rubric. the run stops the moment Jev finishes so Opus stops burning tokens. coming soon to @distribb_io + connector + gpt plugin

I built a voice controlled computer-use for my mac using @typesafeai's Jev and it's INSANE how fast it is! I can dictate "open the notes app and create..." and the app opens before I even finish my sentence.
