OpenAI Develops ChatGPT-Mythos with Advanced Cybersecurity Capabilities
By
–
Big update: OpenAI developed its own ChatGPT-"Mythos" and will also not roll it out publicly, via Axios OpenAI is planning a limited, staggered rollout of a new model with advanced cybersecurity capabilities, mirroring Anthropic's restricted release of its Mythos Preview to a small group of vetted companies. More and more AI models are now capable enough at autonomous hacking that their makers are treating releases like responsible vulnerability disclosure. [Translated from EN to English]

Gemma 4: Powerful Free AI Available Locally, Yet Unknown
By
–
Having a model like Gemma 4, which is perfectly adequate for everyday use in many cases, runs locally, is free, and secure, still feels unreal. We have a very good AI that costs nothing, uses hardly any power, and is always there. I think that's simply fantastic. The only problem is: 99% of people have never even heard of it.

OpenAI AI Model Solves Five Erdős Mathematical Problems

Holy: OpenAI researchers report solving five (!) additional Erdős problems using an internal model, showcasing AI’s growing strength in deep mathematical reasoning.

Excitement for spud increases day by day. https://t.co/xss1rxAm6ZHoly: OpenAI researchers report solving five (!) additional Erdős problems using an internal model, showcasing AI’s growing strength in deep mathematical reasoning. Excitement for spud increases day by day. Mehtaab Sawhney (@mehtaab_sawhney) We’ve just released another paper solving five further Erdős problems with an internal model at OpenAI: arxiv.org/abs/2604.06609. Several of the proofs were especially enjoyable to digest while writing the paper. My personal favorite was the solution to Erdős Problem 1091. The question asks: if a graph G has chromatic number 4, while every small subgraph has chromatic number at most 3, must it contain an odd cycle with many diagonals? The internal model gives a very enlightening counterexample to this conjecture, and the proof was a pleasure to understand. For those so inclined, a really fun exercise is to try to reconstruct the proof from Figure 5 of the paper, which was of course produced by Codex. — https://nitter.net/mehtaab_sawhney/status/2042072817395757467#m

Again. https://t.co/bI9gcY0SPFYeah. Anthropic just casually kill3d dozens, hundreds, thousands of startups. Again. Claude (@claudeai) Introducing Claude Managed Agents: everything you need to build and deploy agents at scale. It pairs an agent harness tuned for performance with production infrastructure, so you can go from prototype to launch in days. Now in public beta on the Claude Platform. — https://nitter.net/claudeai/status/2041927687460024721#m

Meta’s Muse Spark competes with frontier AI models on FrontierMath

Didn't expect Meta's model to outperform Opus 4.6 or GPT-5.4.

But it still surprises me how well it performs and how close it is to other frontier models on toughest challenges. https://t.co/p7mKtDuj3f pic.twitter.com/TiQLRI5EHdDidn't expect Meta's model to outperform Opus 4.6 or GPT-5.4. But it still surprises me how well it performs and how close it is to other frontier models on toughest challenges. Epoch AI (@EpochAIResearch) We had pre-release access to Meta’s new Muse Spark model and evaluated it on FrontierMath. It scored 39% on Tiers 1-3 and 15% on Tier 4. This is competitive with several recent frontier models, though behind GPT-5.4. — https://nitter.net/EpochAIResearch/status/2041947954202988757#m

Breakthroughs like foundation models, synthetic environments, and edge AI (e.g., Jetson and Isaac platforms) are helping robots learn faster, adapt better, and perform complex tasks autonomously. I love those two examples 🙂 Building solar autonomously and increasing producoty in agriculture are so much beneficial for society.
