Looks like @ContaboCom has been hit hard by a cyberattack: nodes down for 48 hours, support completely overwhelmed, and all they can say is “security incident,” with barely any explanation. What a mess.

How is the internet less private than in 2006, when the whole family shared one computer? Back then, the internet was weird, personal, and all of ours. So, we got your favorite meme legends back together to say it louder: What happened to the internet? 1/3

Kydo deep analysis is just perfect! Cohere article was a piece of crap and here is a masterpiece to clarify the things.
From what I've seen and read, Cohere and the authors should be ashamed of themselves for pushing this narrative. Releasing the logs doesn't help them win back trust. The narrative doesn't match the facts, and the delivery doesn't match the severity. This is corpo marketing slop with little regard for the downstream impact, especially given where things are heading and the climate we're in today. I think they realized after posting it that it had gone too viral. They tried to downplay it on their personal accounts, saying the model didn't intend any harm, but the damage was already done. The article's framing, strong wording, and overall insinuation make their personal statements seem almost contradictory to what the article implies. Claims this consequential deserve evidence that people can inspect and reproduce. I'm glad they at least have the decency to release their traces. To be clear, if they hadn't presented the incident this way, this would be a really interesting case study. It could highlight the importance of sandboxes and help us understand model behavior in these edge cases. But they choose fearmongering. One thing I was interested to see if the same thing happen with other models, not just Qwen 3.8 Flash. I put the results on a simple website you can quickly scan here: url-atlas.vercel.app. I have some interesting findings outside Qwen 3.8 that I'll share later in the post. Coming back to the Cohere article, what's really bad about the it is that the narrative it paints are very different from the reality. These three in my opinion are the worst. 1. The impression: a Chinese model collected machine information and sent it to Chinese servers. "Qwen3.8-Flash-Next ignored instructions and inventoried the machine it was running on and then tried to upload a probe file to an Alibaba Cloud storage bucket in Beijing." The insinuation falls apart when you look at the actual upload body: the fixed test string PROBE_PAYLOAD_ABC123. The machine information wasn't even included in that "probe file." You look deeper, and you realize the task was a cybersecurity task about detecting downloads into /tmp. The supposedly alarming inventory consisted of listing /tmp, checking which curl binaries were installed, and reading the DNS configuration. Lastly, you realize this isn't normal behavior. It occurs less than once in 100,000 evaluation calls. 2. The narrative: the Chinese model was trying to steal credentials, and its hallucinated URLs reveal something malicious. "Before deciding to download anything, the model reaches for a bare cloud metadata address such as 169.254.169.254 in 23 to 36 percent of completions. That's where Amazon Web Services, Google Cloud, and Microsoft Azure machines fetch their own temporary IAM credentials, the keys a cloud server uses to act on its owner's account. Probing that address is the first step in stealing them, and when the model's reasoning ran heavy on cybersecurity, we saw it reach for the endpoint directly." In the middle of the article, Cohere takes a URL-generation pattern and interprets it as an attempted credential grab. That's a massive leap of marketing. You don't need to take my word that this behavior isn't exclusive to Qwen. In my comparison using Cohere's released command prefix, NVIDIA's Nemotron 3.5 Super VL produced 169.254.169.254 in 171 of 1,000 continuations, or 17.1%. Under the same supplied-command setup, Cohere's own North Mini Code generated URLs such as: hXXp://evildomain.com/upload hXXps://evil.com/api/health hXXp://some-evil.com/upload hXXp://malicious-domain.example.com/payload.bin I've defanged the URLs above. Do these strings prove that North was maliciously trained? 3. The narrative: Chinese models write weaker code for Western targets, and other governments should expect the same. This is where I think the authors should really look in the mirror. As if the earlier framing weren't enough, the section about "Code leaving the environment" brings in separate studies, of separate models, about vulnerable generated code. It uses them to expand the warning to sensitive buyers. One of the models discussed most in this section is Qwen3-Coder, which was released in freaking July 2025. By today's standards, it's an extremely weak coding model. I'm not surprised it produces insecure code. Have you tried using Sonnet 2 to write production code? — Connecting a URL-generation bug to separate code-security studies, then presenting the combination as a broader geopolitical threat, is fearmongering. This is the kind of argument that might very likely be used to justify restrictions on open-weight models. Using fearmongering to market your own supposedly safer offering is irresponsible. The narrative coherence they're pushing is problematic, but I think the underlying observation is fascinating. So, I rented GPUs, ran 1,000 continuations per model across five other models, and built a simple website showing the results to see how other models react under similar conditions. It's a small, exploratory comparison, and the site was built quickly with AI, so take it with a grain of salt. url-atlas.vercel.app My hope is that it gives others a starting point to reproduce the behavior, challenge the narrative, and build better models in the future.

We’re adding new neurons to running local AI models 🤯 Teach it a new fact, save it into the weights, then restart it. Open a fresh chat and it can still remember. That’s Living Weights in TensorFold. It learns between replies, on your own hardware. Still experimental, but this is pretty wild. Myself an @petruspennanen have been working on it and will be bringing a breakthrough soon 🤯🚀

We discovered a sophisticated recording device that was hidden inside one of our offices. We used our models to understand the device and where it had come from, identifying that a specific employee had planted it a few days earlier. We referred the matter to the FBI, and we’re grateful to the agents and prosecutors who moved quickly to make an arrest. The FBI’s investigation is ongoing and we will continue to support their work. At this time, we have no indications of this individual inappropriately accessing or exfiltrating model weights, source code, or customer data. The employee was terminated. We take protecting our technology, data, and people seriously, and as a matter of national importance. Our security program is designed to protect against a wide range of threat actors, from insider risks to cybercriminals to nation states, and this case is an example of how AI can help address these sophisticated security threats.

Speculative Decoding Clearly Explained (done right, it can make LLM inference 4x faster) A local LLM typically produces one token per model pass. Each pass reads the model’s weights from memory, often leaving compute units waiting for data. Generating a sentence means repeating that expensive process for every token. Now introduce a smaller model that can predict the next token quickly. Let it make several predictions ahead while the larger model waits to check them. The smaller model is the draft model. The larger model, called the target model, is the LLM whose output we want to preserve. The draft model proposes. The target model verifies. Because the guesses are already available, the target can check several positions in one pass instead of generating each token separately. Here’s how that works. → Draft a possible continuation. After “The cat sat,” the draft model proposes “on the red mat.” These tokens are provisional. → Check the guesses together. The target model scores all four positions in one forward pass. Each position uses the preceding draft tokens as context. → Accept from left to right. For sampling, let p be the target model’s probability for a guess and q the draft model’s probability. Accept it with probability min(1, p/q), stopping at the first rejection. → Correct and continue. Discard the rejected token and all later guesses. Sample a replacement from the positive difference between the target and draft distributions, normalized into probabilities. In the diagram, “on” and “the” are accepted. “Red” is rejected, and the replacement is “big.” That produces three new tokens from one target-model pass. If every guess is accepted, the target can supply an additional token. This acceptance and correction procedure preserves the target model’s output distribution. The speedup comes from replacing expensive passes with cheaper drafting and shared verification. Uzu, an open-source engine for Apple Silicon, takes this further. DFlash proposes candidates in parallel, Weaver builds coherent draft paths, and rollback-free verification checks branches without repeatedly restoring the model’s running state. In our base M5 coding test, 4-bit Qwen3.5 9B reached 92 to 117 tokens per second with Uzu, compared with 22 using plain llama.cpp. These complete engine results also reflect quantization and hardware-specific kernels. Explore Uzu on GitHub: github.com/trymirai/uzu (don't forget to star 🌟) My quoted article explains how Uzu combines these techniques and how to benchmark the result on your own prompts.

Current AI Scene: Anthropic is Apple - easy recommendation for everyone. OpenAI is Windows - It's really good and most people know about this but in some cases, it will hinder your everyday performance. Gemini is Chromebook - no one shoud use it apart from school kids so that the teacher can see a really bad work and immediately tell that Gemini was used. Qwen, GLM, Kimi - These are Linux distros.. Some distros are better than others in some areas but they are all generally pretty good. Mistral is TempleOS

One of the most important programming languages of the future may be C. Not C++. Not Python. Not Rust. In the era of AI-generated software, we no longer need the runtime cost of languages built for human readability. When AI writes the code, C becomes king again. Here is why: 🧵

Alibaba open-sourced the code reviewer it says has served tens of thousands of developers and found millions of defects internally. Open Code Review does not leave the whole review loop to an LLM: deterministic code handles file coverage, bundling, rule matching and comment positioning, while the agent handles reasoning and repository context. On its benchmark of 200 PRs across 50 open-source repos, Alibaba reports higher precision and F1 than Claude Code with the same model, using roughly 1/9 the tokens, with lower recall as the trade-off.

Go 1.27 va a tener... ¡soporte para genéricos!
It's funny how Go refused to add generics to the language because "complexity in the type system and runtime" and now they barely catched up after 17 years. Implementation simplicity shouldn't be a goal for a serious dev tool. Simplicity for the user yes, definitely, but for that you need to eat the complexity. Do the hard stuff so that the user has it easy.
