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.


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


@GoogleVRP AI totally changed vulnerability research/ bug hunting. The Chrome VRP is officially dead. The reward amount is 10x less.


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/Xi… 📄 Blog: #blog" target="_blank" rel="nofollow noopener">mimo.xiaomi.com/index#blog

Fixes/PR from @kernelpool for MiniMax M2.7 local issues with MLX has been merged in mlx-lm! LFG 2🔥.7🔥 Thanks @angeloskath 🙏



😱 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/ge… 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 👇

Labour abandons UK car industry, shamefully relaxed about unfair Chinese car imports Only @reformparty_uk will protect UK car industry & jobs Reform will impose heavy tariffs & small quotas of these subsidised Chinese cars bbc.co.uk/news/articles/…

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
