April 2026 turned out to be one of the most explosive months in AI history. OpenAI dropped GPT-5.5, Anthropic sparked debate by withholding Claude Mythos, and new releases from Google, DeepSeek, and other Chinese labs pushed reasoning, agentic capabilities, and multimodality to new heights.

Claude Mythos and GenAI are reshaping security — discover why faster exploits, endless patching, and resilient detection now define defense.

In this tutorial, we explore kvcached, a dynamic KV-cache implementation on top of vLLM, to understand how dynamic KV-cache allocation transforms GPU memory usage for large language models. We begin by setting up the environment and deploying lightweight Qwen2.5 models through an OpenAI-compatible API, ensuring a realistic inference workflow. We then design controlled experiments where […] The post A Coding Implementation on kvcached for Elastic KV Cache Memory, Bursty LLM Serving, and Multi-Model GPU Sharing appeared first on MarkTechPost.

The US Cybersecurity and Infrastructure Security Agency (CISA) does not yet have access to Anthropic’s bug-hunting AI model, Claude Mythos, even though other government agencies do, Axios reported earlier this week. As if that weren’t a big enough slap in the face for the national cyber-defense agency, the list of those who do have access to Mythos includes several unauthorized users, according to Bloomberg News. Members of a private Discord channel specializing in seeking information about unreleased AI models, have gained access to Mythos, according to one unnamed member of the group, Bloomberg reported. “The group has been using Mythos regularly since then, though not for cybersecurity purposes,” the person told Bloomberg, supplying screenshots to back up their claim. As a result of its fear that the powerful model could be used to identify and exploit flaws in software and online services, Anthropic has limited access to a preview of Mythos to an exclusive group of government agenc

Anthropic's Mythos AI is being kept behind closed doors as governments assess what faster, AI-driven vulnerability discovery means for cybersecurity.

Anthropic's tightly controlled rollout of Claude Mythos has taken an awkward turn. After spending weeks insisting the AI model is so capable at cybersecurity that it is too dangerous to release publicly, it appears the model fell into the wrong hands anyway. According to Bloomberg, a "small group of unauthorized users" has had access to Mythos - whose existence was first revealed in a leak - since the day Anthropic announced plans to offer it to a select group of companies for testing. Anthropic says it is investigating. That's a rough look for a company that has built its brand on taking AI safety seriously while touting the cybersecurity … Read the full story at The Verge.

Tech can scale cyber-attacks and defences alike, raising questions about private power, public risk and the future of a shared internet Anthropic announced its latest AI model, Claude Mythos, this month but said it would not be released publicly, because it turns computers into crime scenes. The company claimed that it could find previously unknown “zero-day” flaws, exploit them and, in principle, link these weaknesses in order to take over major operating systems and web browsers. Mythos did so autonomously, writing code and obtaining privileges. The implications are significant. It’s like a burglar being able to target any building, get inside, unlock every door and empty every safe. The Silicon Valley company has so far named 40 organisations as partners under Project Glasswing to help mount a defence – asking them to “patch” vulnerabilities before hackers get a chance to exploit them. All are American, sitting at the heart of the US-led digital system. Anthropic shared Mythos with
