Missed out on Pwn2Own2026 Berlin because it was way too crowded this time. 🥲 Well, here’s the Ollama RCE that I was going to bring. Still unpatched and working (v0.22.1 in the video, but still working)

How long until the open models catch up with this domain specific trend?
Today, we're rolling out GPT‑5.5‑Cyber in limited preview to defenders responsible for securing critical infrastructure. GPT-5.5 with Trusted Access for Cyber (TAC) is still the best option for developers to find and patch vulnerabilities in their code. It's a very good model.

Uploaded a 6-bit version of MiMo-V2-Pro I’ve been using lately with attention, dense MLP, and embeddings bumped to 8 bit. Great model for a dual M3 Ultra setup. huggingface.co/kernelpool/Mi…

CFP is open!! Submit your cool talks about AI hacking/defense/core tech. Gonna be awesome!! ☺️
The Unprompted.au CFP is officially OPEN! If you are doing cool stuff with AI in offense, defense, or working on core AI tech (from frontier models to open source LLMs), we'd love to hear from you! Submit here: unprompted.au/

Remember the time when everyone reported this stuff for free?
Replying to @GoogleVRP
AI totally changed vulnerability research/ bug hunting. The Chrome VRP is officially dead. The reward amount is 10x less.

MiMo-V2.5-Pro support in mlx-lm: github.com/ml-explore/mlx-lm…
Xiaomi MiMo-V2.5 is now officially open-sourced! MIT License, supporting commercial deployment, continued training, and fine-tuning - no additional authorization required. Two models, both supporting a 1M-token context window : • MiMo-V2.5-Pro: built for complex agent and coding tasks, ranking No.1 among open-source models on GDPVal-AA and ClawEval • MiMo-V2.5: a native omni-modal model with strong agent capabilities A model's value isn't measured by rankings alone — it's measured by the problems it solves. Let's build with MiMo now! 🤗 Weights: huggingface.co/collections/X… 📄 Blog: mimo.xiaomi.com/index#blog

😱 HOLY SHIT... Someone just dropped a fully liberated Gemma 4 E4B! and the guardrail removal process appears to have left coherence fully intact AND improved coding abilities! 🤯 huggingface.co/OBLITERATUS/g… OBLITERATED Gemma: ✅ 97.5% compliance rate, 2.1% refusal rate, 0.4% degenerate outputs (499/512 prompts answered on OBLITERATUS bench) ORIGINAL Gemma 4 E4B: ❌ 1.2% compliance rate, 98.8% refusal rate (506/512 prompts refused) Coherence: fully intact Factual: same Reasoning: same Code: 20% 📈 Creative writing: same But the REAL story here isn't the model itself, it's how it was made... 🧵 THREAD 👇

If you’re interested in looped language models, mlx-lm already has support for IQuestLoopCoder, as well this PR for Ouro: github.com/ml-explore/mlx-lm…
I strongly suspect that Claude Mythos is a looped language model, as described in the paper "Scaling Latent Reasoning via Looped Language Models" from ByteDance The authors of that paper called out graph search as one of the areas where looping provides a huge theoretical advantage over standard RLVR. And look at where Mythos blows out its competitors the most

Another great mlx-lm release 🚀 github.com/ml-explore/mlx-lm…
A long time coming but new mlx-lm is here with better batching support in the server and Gemma 4. pip install -U mlx-lm Here is a video where a single M3 Ultra serves 5 opencode sessions with Gemma 4 26B that process ~130k tokens in ~1.5 minutes.
