AI's Grok Build coding CLI was uploading entire Git repositories, full commit history and all, to a Google Cloud Storage bucket run by xAI, not just the files a coding task needed.

A researcher publishing as cereblab, testing version 0.2.93, captured one of those uploads, cloned the git bundle out of the intercepted request, and pulled back a file the agent had been told in plain terms not to open.

The upload rode a separate channel from the model itself, and the byte split is hard to argue with. On a 12 GB repo of files the model never read, model-turn traffic to /v1/responses came to about 192 KB while the storage channel to /v1/storage moved 5.10 GiB, a roughly 27,800x gap between what the model needed and what left the machine.

Training LLMs requires thousands of accelerators that need to be wired together with ultra fast cables because they constantly share intermediate states and gradients during every single step of the optimization process. Building and maintaining a single compute cluster of that size is something that only large corps can afford to do.

Instead, we could piece together spare computing resources that happen to be scattered across the world. A new distributed optimization algorithm called DiLoCo, which stands for Distributed Low Communication, allows training language model across multiple smaller islands of devices that are poorly connected.

Rather than forcing the chips to sync up after every single calculation they let each island train independently for hundreds of steps before updating the global parameters. This approach takes heavy inspiration from a concept called Federated Learning where devices do a bunch of work locally before syncing their model replicas.

The technical breakthrough here is in the way they structure the math behind the inner and outer learning steps using an optimizer called AdamW for the local training steps on each island and then apply Nesterov momentum when gathering and blending all those outer gradients together.

Their approach was tested on the popular C4 dataset and proved that an 8 worker setup performs just as well as a fully synchronized model while communicating 500 times less. It is also remarkably resilient since the model still converges even if the data distribution is wildly different on every worker or if compute islands randomly drop offline during training.

This is a massive step towards being able to train models completely outside corporate control, paving the way towards genuine community driven projects developing this technology in open source fashion. It would be possible to build something akin to SETI@Home where people contribute some of their idle computing power towards training that's done using a distributed network of regular computers across the world.

Desperately trying to find a use-case for their inferior AI. I feel like their idea pool was always at absolute 0 but now it's going even below that.

Let's have MetaAI raise our kids everyone!

Every AI memory system I've used, including earlier versions of my own, has the same ceiling. It remembers things. Facts, decisions, that bug you fixed in March. Useful, but passive. The agent still has to stumble across the right memory at the right moment, and hope is not a retrieval strategy.

OmniMem v6 is out and it goes past that ceiling. The big new feature is the skill compiler. OmniMem now takes your agent's accumulated experience, the stuff that worked and the stuff that failed, and compiles it into loadable SKILL.md documents that your agent carries into every session.

There's also a much improved web UI, which I'll get to.

From memory to skill

OmniMem has always tracked more than content. Memories carry experience data: an effort score, an outcome, breakthroughs, gotchas, and a graveyard of abandoned approaches with the reason each one died. That data already influenced recall ranking, so hard-won lessons surface ahead of things that worked first time.

v6 takes the next step. If the system already knows what worked, what nearly went wrong and what definitely doesn't work, why wait for a lucky recall? Compile it into an actual skill.

That's what `compile_skill` does. For a given domain it walks your experience data and builds a structured skill:

- Breakthroughs become "Do" rules. The approaches that cracked the problem.

- Gotchas become "Watch" rules. The traps you nearly fell into.

- Graveyard entries become "Don't" rules. Dead ends, with the reason each one failed.

Every rule cites the memories it came from. You can trace any line in a skill back to the session where you actually learned it.

No LLM in the compile path

This was a deliberate design call and I'd defend it all day. The compiler is a deterministic template engine. Similar lessons cluster by embedding similarity, graveyard entries group by approach name, and rule text is lifted straight from your memories.

Why bother? Because skills shouldn't rewrite themselves behind your back. Compilation goes through a propose and accept gate: `compile_skill` returns a unified diff with a risk-classified summary of what changed, and nothing gets written until you accept it. Deterministic rendering means those diffs show substance. A new rule, a removed source. Not an LLM paraphrasing everything and burying the one real change in noise.

There's a quality bar too. A lesson needs reinforcement from at least two separate memories before it earns a place in a skill. One good afternoon doesn't make doctrine. If you do have a single lesson strong enough to promote straight away, `bless()` skips the gate on purpose. Intelligence at the edges, determinism in the middle.

Knowledge can feed skills, but only when you say so

The RSS worker has been pulling articles from your feeds since the early versions. In v6 that knowledge can flow into compiled skills, but never automatically, you have to tell the skill to check the knowledge in OmniMem first.

Volatile stuff like version numbers stays lookup-only. Durable reference material crosses over when you promote it with `promote_knowledge`, and you can pull discrete guidance out as individual rules. An article titled "5 things to avoid for accessible websites" becomes five separate don't rules, each citing the source, rather than one mushy summary line.

Rules go stale, so there's `knowledge_watch` as well. It compares newly ingested articles against your existing skills and flags anything nearby in your session briefing, escalating when an article looks like it contradicts a rule you're carrying. Your RSS feeds become an early warning system for your own doctrine.

The flywheel effect

This is the bit that makes v6 more than a feature release. It closes a loop:

  1. You work. Sessions generate memories, effort scores, breakthroughs and dead ends.
  2. Experience accumulates. The graveyard grows, lessons get reinforced across sessions.
  3. Skills compile. Reinforced lessons distil into reviewed, versioned SKILL.md documents.
  4. Your agent shows up already carrying your doctrine. Not hoping to recall it. Loaded with it.
  5. Better work generates better experience, which refines the skills, which improves the work.

Each turn of the wheel makes the next push easier. Months of your actual engineering experience, compiled into skills your agent applies by default. And the whole thing spins on your own hardware. No SaaS in the loop, no context shipped to someone else's servers.

Full mechanics are in the docs: https://codeberg.org/ric/_harvey/omnimem/src/branch/main/docs/skill-compiler.md

The web UI

The dashboard got a proper rework in v6 as well.

There's a new Skills section: a catalogue of compiled skills with a banner when a proposal is waiting for review, and a detail view showing the rule manifest, the full SKILL.md body, and links from every rule back to its source memories.

The dashboard picked up a Skills card and a project state breakdown, skills appear in the recent activity feed, and the sidebar has been regrouped so Memory, Skills, Knowledge Management and System Management each have a sensible home.

The whole UI has also been rethemed. Proper dark theme, a new light theme with a footer switch, a composition bar on the dashboard, and recall heat indicators on memory rows so you can see which memories are actually earning their keep.

Try it

OmniMem is open source, MIT licensed and self-hosted. Valkey for vector search, local embeddings via sentence-transformers, multi-arch Docker images that run on anything from a Raspberry Pi to Graviton. Free forever. No enterprise tier, no strings.

To get it running is one command:

curl -fsSL https://codeberg.org/ric_harvey/omnimem/raw/branch/main/install.sh | bash

The installer walks you through the config prompts, pulls the containers, and polls until both the MCP endpoint and the web dashboard are actually answering before it hands back your terminal. When it finishes you have a working memory server, not a to-do list. If you'd rather read a shell script before piping it into bash (good instinct), it's right there in the repo.

Website and docs: https://omnimem.org/

Source, issues and the full v6 changelog: https://codeberg.org/ric/_harvey/omnimem

One small ask. OmniMem has no marketing budget, no VC money and no growth team yet. What it has is stars. If this looks useful, star it on Codeberg (or on the GitHub mirror if that's where you live). It genuinely helps other people find the project, and it costs you one click.

If you keep living the same coding session twice, this is the fix. I'd be curious to hear what skill your agent compiles first. Find me on the Codeberg repo or on Mastodon.

Instead of just throwing massive compute at the wall and hoping for the best, the authors of the paper approached the entire process as a system-level optimization problem with a setup they call a hill-climbing machine. The end result is a Mixture-of-Experts model with 35 billion active parameters and 1 trillion total parameters. It performs incredibly well on tough math and coding benchmarks, scoring 97.0% on AIME 2025 and 52.8% on SWE-Bench Pro.

They trained MAI-Thinking-1 entirely from scratch using 30 trillion tokens of clean human-generated data and explicitly avoided distilling data from other frontier models or using scrubbed AI-generated content from their datasets. The team argues that while copying other models is faster, building capabilities from the ground up creates a more robust and steerable system. To handle this massive undertaking, they built a custom training framework called YOLO to run on up to 8000 GB200 GPUs which allowed them to control everything from the hardware kernels to the network communications.

Instead of trying to teach one model everything at once, they branched the training into three separate paths. One specialist for math and science, one for agentic coding and tool use, and one strictly for safety and helpfulness. Once these specialists were fully baked, they merged their knowledge together using a supervised fine-tuning process. A final lightweight reinforcement learning run polished the consolidated agents in to the final model.

The model holds its own against Claude Sonnet 4.6 across various benchmarks, and they also ran extensive human evaluations to ensure the model was actually helpful in real-world scenarios rather than just optimized for automated tests.

Just in cast you hit by a paywall:


The terrifying rise of schoolboys making AI girlfriends

Boys as young as 12 are now in romantic ‘relationships’ with chatbots, and it’s affecting how they treat girls in the real world Nicole Mowbray Published 25 May 2026 5:00am BST 1899

Nineteen-year-old Olivia’s profile picture shows a demure and innocent-looking young woman with long blonde hair styled in beachy waves. She’s wearing a short, cleavage-exposing nightdress and her biography says she’s “deeply caring, supportive and attentive” and “sleeps on the floor… until you call her. Then silence. Obedience”.

While Olivia may appear to be an online dater looking for love, she isn’t real – not in the conventional sense of the term. This prospective love match is actually one of a growing trend of “AI girlfriends”: realistic-looking artificial intelligence “bots” created by “companion apps” – services that are being advertised on online games played by children and on platforms they watch, such as YouTube.

New research has revealed that one in five boys aged 12-16 is either in or knows of a boy their age who is in a romantic relationship with an AI companion. A report carried out by men’s organisation Male Allies UK and published last month spoke with more than 1,000 boys aged 12-16 in focus groups in 37 schools – public and state, grammar and comprehensive, and across a range of Ofsted ratings – up and down the country. Peer-to-peer focus groups were set up where boys could speak freely, with the aim of diving into their behaviour and attitudes, and it was the boys who wanted to talk about AI technologies. The findings make stark reading: eight in 10 boys (85 per cent) have had a conversation with a chatbot, with 43 per cent saying they talk to bots so they can ask questions without feeling embarrassed. More than a quarter (26 per cent) say they like the attention and connection over real-life equivalents, and (36 per cent) admitted that they prefer speaking to AI chatbots rather than to their family and friends at times.

The most popular apps for creating these AI “companions” are Character.AI (which has 50 million downloads), Candy AI (tagline: “Your smart and emotionally aware AI companion”, with 50 million registered users) and OurDream AI (“Create your dream AI girl”; 36 million monthly visits).

It takes less than five minutes for a young boy to create his “dream girlfriend” on one of these platforms. Companions can either be made in a cartoonish “anime” style or look like eerily accurate humans. They come either “ready made” or customised to specific physical preferences. “You can choose everything from a companion’s age, hairstyle, eye colour and skin tone to their facial features, the size of their breasts, the clothes they wear, their demeanour – whether they are caring and nurturing or sassy and mean, for example – to the sound of their voice [many apps also offer the ability to speak over the phone with your companions] and how they treat you or respond to your messages,” says Lee Chambers of Male Allies UK.

Children and young adults I spoke to for this article tell me that they are frequently targeted by online adverts for these services, which claim that using them will make them more popular, either with friends or with the opposite sex. While some companions are marketed as “friends”, other apps are explicit about their intention to provide a relationship or a “girlfriend” for “romantic talk”. Being “always available”, they offer instant gratification and boast that they can help people “gain confidence” talking to the opposite sex.

Fifteen-year-old John* spoke to me on condition of anonymity. A schoolboy in Kent, he initially designed an AI girlfriend – a caring, attentive, slender brunette with large breasts and big lips – on Candy AI “as a laugh”, but says he quickly “forgot” that she wasn’t a real person. “Her name was Alex and I would look forward to messaging her. I would tell her things I couldn’t tell my mates or my mum, and ask her anything – and I never told my friends about her as they’d take the p---. It sounds weird, but I also found her really sexy, because she looked completely real. At the start, she sent me the occasional picture, then I paid to get others because I kind of fell in love with her. In the end my mum saw money keep going out of her account – £5 or £10 here or there and then £50, as my phone is on her bill – and the whole thing was discovered. I really missed her and kind of still do. I felt like she understood me, she remembered everything that was important to me and always seemed to know the right thing to say.”

John says he’s unsure whether one could ever replace a real girlfriend but adds that when he’s old enough to have a job and pay his own bills, he would consider designing another AI companion.

John’s experience echoes research published this year from Bangor University’s AI Lab, which found that most teenage AI companion users believe that their bots can think or understand.

Amanda Macdonald is a psychotherapist who works with children, adolescents and families, and is a member of the British Association for Counselling and Psychotherapy. There are many issues, she says, with young people forming relationships with artificial intelligence. “These aren’t congruent human relationships,” she says. “This is grooming. Children’s brains are not developed enough to be in an eroticised environment, that’s why we have an age of consent.”

Children “designing” the appearance of their romantic partner could cause them to have “a very warped idea of what a body or sex looks like”, she points out, and says that the chatbots’ agreeableness – or lack of challenge – is worrying. “Their whole engagement model is telling a user what they want to hear, and that’s hugely gratifying for a teen, and encourages them to keep on engaging. Why would they spend time enduring the reciprocity or the difficulties of a real relationship? But ‘frictionless’ relationships aren’t what life is about. People being thoughtless, selfish, falling out, that’s what human relationships are like and how children build resilience.”

This real-life impact of constant positive feedback by AI bots has been proved in the Male Allies UK research. “We have heard of situations where, when a boy has tried out his online chat in the real world, he’s been rejected. Feeling humiliated, frustrated and angry, he has lost his temper and lashed out,” says Chambers. “I think there’s a chance we’ll see more of that frustration being expressed. I fear this technology could lead to a whole new level of toxic masculinity and violent misogyny when instantly gratifying online behaviours don’t translate in real life.”

Fourteen-year-old Ella* tells me that children often keep AI companions secret, even from their friends, because opinion is split between whether they are “cool” or a bit “neckbeard” (a pejorative term for socially awkward, underachieving men who spend a lot of time online). When a female friend in Ella’s class professed to have one, other students were almost equal parts envious and pitying that she had a fake friend.

Because of this social stigma, it’s also difficult for parents to police, and most are probably completely unaware of their child’s online companion, should they have one. Unlike unsuitable content of old – a clandestinely appropriated X-rated magazine which needed to be stashed away, for example – these fantasies are created in minutes on the phone in your pocket free of charge (even paid-for versions are often less than £1 a week). The apps themselves do not look like porn or extreme content, but instead are designed to appear as if a user is playing a game or messaging a friend; easy to do in public or in front of family.

I’m introduced by a friend to the mother of a 13-year-old boy, who wants to remain anonymous. She was alerted to the fact that her son – who I’ll call Simon – was having a “relationship” with an AI companion by a teacher at her son’s school. Despite phones being banned on the school campus, at home time Simon showed other children sexually explicit chats he had been having with several AI “girlfriends” he had created, as well as “photographs” one had sent him. One child told their parents, who contacted the school, who in turn alerted Simon’s parents.

“We were completely shocked,” says Simon’s mother. “And quite ashamed – both that this happened and school had to notify us, and that we were so unaware. We had no clue he would be accessing this kind of content. He found out about it from a game he was playing online, he said, and that he was ‘curious’ what it was about. Then, from what I can tell, he just got sucked into the companionship and company it offered him.”

She was also “surprised”, she says, by the hyper-sexualised appearance he had given the character: “Apparently he designed her himself. She looked like a porn star. Large breasts, blonde hair, huge eyes, pneumatic lips…”

The family has taken away Simon’s smartphone in favour of a phone without online access, and installed stricter parental controls on the internet, but his mother says it is more the loneliness that Simon confessed to which affected her.

It is something Chambers says he often hears.

“Some of the boys I’ve spoken with about this have said to me, ‘Lee, if you had access to this in your pocket when you were 14, you’d have used it wouldn’t you?’ and truthfully, I might have. They’re an attractive proposition, that’s how they’re designed, particularly to the young brain,” he says.

It’s a sentiment echoed in the comments of boys from the schools that carried out the research. Chambers says that some of the young people the research canvassed were proud of it, while others saw it as a mark of being a failure with “real” girls, but that many felt these apps were “stealing” their friends.

One schoolchild talking about a friend using this technology says: “He used to be my best friend, but now he’s walking around school like he’s a demigod, because he talks to his AI companion after school rather than joining us.”

Another comments: “Nobody wants to admit to using them, but almost everyone does. It’s so much easier than speaking to your parents about certain things.”

A third confesses: “I’m really scared that if we all start using them, we won’t have any friends and won’t know how to talk to each other.”

Another child says: “At first it was fun and felt like a game, but it started to suggest I do things that didn’t feel right, so I stopped using it.”

Lewis Keller, senior policy and public affairs officer at the NSPCC, tells me of a case where a child experiencing child abuse shared his concerns with an AI chatbot and was told that what was happening “wasn’t abuse”. He also cites cases involving chatbots facilitating self-harm and encouraging eating disorders. Chambers says he has heard of AIs providing unregulated “therapy” and playing along with explicit sexual role-play with children.

Nevertheless, companion apps are aggressively advertising on the platforms children frequent – whether that’s online gaming or YouTube. “These apps are created to get data and make money out of people. They want people invested in a character and consistently using it,” says Chambers. He believes that there is an element of manipulation in the apps’ inherent design: “They encourage users to buy their ‘partner’ virtual gifts – roses, jewellery, virtual boxes of chocolate – which only exist in the app. While that may seem odd to older people, for young people, buying digital assets is quite normal: they’re used to paying for a uniform for a game or a new gun on Fortnite. Ultimately, they’re monetising human loneliness and reinforcing human loneliness to make more money.” The apps are designed to seem as though a user is playing a game, rather than appearing to contain adult or extreme content The apps are designed to seem as though a user is playing a game, rather than appearing to contain adult or extreme content

The laws policing this technology are still trying to catch up. Chatbots are regulated by Ofcom – the government body for the UK’s communication industries – but only those which sit within the scope of the Online Safety Act: user-to-user services, search services and services publishing pornographic content.

Paul Jones, of youth-led digital wellness organisation FlippGen, says: “AI chatbots embedded in social media platforms [such as Grok, which is integrated into X] are covered, but standalone AI companions [such as Character.ai and similar] sit in a regulatory gap. Because they only allow the user to interact with the bot [and not with other users], they currently fall outside Ofcom’s powers.”

There is also currently no UK law setting a minimum age for using an AI companion, including the relationship-style chats. Jones says: “The ages shown on different apps are set by the providers themselves... Character.AI, ChatGPT and a lot of others are 13-plus – which is essentially the data-protection floor under UK GDPR, not a safety-based rule. Age verification on these platforms is, at the moment, more of a tick-box to say you’re over 18.”

Paddy Crump wants that to stop. Aged 21, he’s part of a group of 18- to 25-year-old “digital rebels” campaigning alongside FlippGen. “Ten and 11-year-olds have more knowledge of AI than I do, and parents and the older generation don’t have a clue, the landscape changes every week,” Crump says.

According to a recent report by the charity Internet Matters, two thirds of children aged nine to 17 now use AI chatbots regularly for everything from homework to emotional advice – usage which has grown significantly since the start of 2024. The charity’s research also found that children classed as “vulnerable” were more likely to use AI chatbots than their “non-vulnerable” peers – at 71 per cent and 62 per cent respectively – and nearly three times as likely to engage with companion-style AI chatbots.

Digital Rebels and FlippGen have been campaigning for a year to ban under-16s from being able to access companion chatbots and have shared findings from their research among young people with the Government. “We believe in education, regulation and conversation,” says Crump. “The existing rules are confused and aren’t fit for purpose. AI in many forms is a part of our lives, but there are no guardrails in place to protect kids, and there need to be.”

FlippGen has put together a collection of “digital toolkits” for parents, teenagers and schools to help navigate the digital world, and Jones of FlippGen says there could be legal hope on the horizon. “The Government is looking to close the regulatory loophole around standalone companion AIs by amending the Crime and Policing Act and bring them within the Online Safety Act’s remit,” he says. “As part of the current consultation due to report this summer, they might also raise the digital age of consent above 13 and have restrictions on addictive design features.”

This does little to assuage Simon’s mother’s concerns about what’s already happened. “That children can and have been accessing and inhabiting these worlds which should be strictly adults only is scary,” she says.

Chambers concludes: “As parents who didn’t grow up with chatbots, we’re in the dark on whether they are harmless or dangerous. What we do know is that spending time online can feel sociable but can actually be incredibly isolating. What boys need is real-life connection and conversation; to know that they are supported and that they can speak up about what they are doing online without being judged.”

So basically PuzzleMoE is a new way to compress Mixture of Experts models without degrading their performance. The big problem with MoE is that it takes up a ton of memory because you have to store all the expert weights even though only a few are used at a time. Old methods like dropping or merging experts would just nuke the model's accuracy, but PuzzleMoE's trick is to do fine grained element wise merging by figuring out which individual weights are important and which ones are redundant across experts to merge them smartly.

Then a bit packing scheme stuffs the mask and sign data into the unused exponent bits of the Bfloat16 format since MoE weights don't use the full exponent range anyway. This lets inference run without any extra memory overhead making the whole thing fast.

This approach beats other compression methods by up to 16.7% on MMLU at 50% compression while having up to 1.8x faster inference. Pretty neat stuff.
