NEW Claude Capybara is INSANE! ๐ฑ
Claude Capybara is a leaked, unreleased AI model from Anthropic that represents a massive leap beyond their current most powerful model, Opus. The model accidentally leaked through exposed internal files, revealing advanced cybersecurity capabilities, autonomous agent features, and persistent memory that has made Anthropic cautious about public release.
Summary
Claude Capybara (internally called Claude Mythos) is an unreleased AI model from Anthropic that accidentally leaked when around 3,000 internal files and over 500,000 lines of code were exposed due to a content management system error. The model represents what Anthropic describes as a 'step change' - not an incremental improvement but a fundamental leap beyond their current flagship model, Opus. The leaked information reveals that Capybara has unprecedented cybersecurity capabilities, described as 'far ahead' of any other AI in this domain, able to find vulnerabilities and understand digital infrastructure at expert levels. This has caused significant concern in the cybersecurity community about potential misuse. The model also features cross-domain thinking, connecting ideas across multiple fields simultaneously, and superior reasoning and coding abilities. Beyond raw intelligence, the leaked code references a 'Cairo system' suggesting always-on AI agents that work continuously in the background, plus persistent memory systems that would remember conversations and user patterns over extended periods. Anthropic is keeping the model in limited early access testing rather than public release due to safety concerns about its autonomous capabilities and power level. The leak has already changed the AI landscape by revealing the direction of next-generation AI development, moving toward systems that work alongside users continuously rather than as tools that are picked up and put down.
Key Insights
- Anthropic describes Claude Capybara as representing a 'step change' rather than incremental improvement, comparing it to going from a bicycle to a jet rather than a slightly faster bicycle
- The leaked information described Claude Capybara as 'far ahead' of any other AI in cybersecurity capabilities, able to find vulnerabilities and move through security problems faster than human experts
- Hidden in the leaked code were references to a 'Cairo system' indicating development of always-on AI agents that run continuously in the background rather than only responding when prompted
- The leaked code revealed persistent memory systems that would allow Claude to remember conversations from weeks or months ago and build a comprehensive picture of users over time
- Anthropic is testing Capybara with only a small group of early access users because they are not yet confident they can release it without serious risks, showing extreme caution even from its creators

[0:00] New Claude Capiara is insane. This AI was so scary. It got leaked before it even launched. Anthropic built something so powerful they are scared to release. It got leaked by accident. And what's inside is wild. We're going to break down everything they didn't want you to see. Stay with me. This one changes everything. So, first, what even is Claude Capiara? You know Claude, right? Made by Anthropic. One of the best AI tools out there right now. Claude has three levels. You've got Haiku at the bottom, then Sonnet in the middle, then Opus at the top. Opus is the smartest, [0:30] the most powerful, the best one they've got. Well, Cappy Barrow goes above Opus.โฆ

Google AI Studio Just Got A Huge Security Upgrade
Google is reportedly developing a new "Security Check" mode for AI Studio that would apply secure coding practices to AI-generated applications. The feature aims to automate security verification during app development, addressing common vulnerabilities like exposed keys, weak authentication, and data access issues before deployment.
New Gemini Skills Update Is WILD!
Google has launched Gemini Skills, a new feature allowing users to save custom instructions once and reuse them repeatedly by typing a slash command, replacing the discontinued Gems feature. Skills can include reference files, be combined together, and are built on an open file format (skill.md) that allows portability across different AI tools.
NEW Codex CLI Update Is ABSURD!
OpenAI's new Codex CLI update transforms terminal-based programming assistance by enabling multiple AI agents to work simultaneously on different tasks, visible in a full-screen control center interface. The update includes features like Agent View, work trees, voice control, and parallel task execution, fundamentally changing how AI assistance operates from sequential Q&A to autonomous team-based work management.
NEW Hermes Cloud + Agent OS is Crazy! ๐คฏ
Hermes Cloud combined with Agent OS enables users to deploy AI agents in the cloud 24/7 using free models without API keys or local setup complexity. The system provides persistent memory, sandbox isolation, and integration with custom workflows like content research, competitor analysis, and news monitoring.
Manus 2.0 Just Changed AI Agents Forever
Manas 2.0 represents a fundamental architectural overhaul that enables users to create games, websites, videos, and automations through simple text requests, with the key innovation being editable components rather than fixed outputs. The platform uses a new Cascade engine that reduces token usage by 23% and improves task speed by 28%, while maintaining all project elements in one connected workspace.
