Description

Claude Mythos Preview is a next-generation language model designed with exceptional capabilities in cybersecurity analysis and exploit development. It has demonstrated the ability to autonomously identify zero-day vulnerabilities in major operating systems, web browsers, and widely used software. The model can go beyond detection by constructing functional exploits, including remote code execution and privilege escalation chains. It uses agentic workflows to explore codebases, test vulnerabilities, and validate findings without human intervention. Mythos Preview can also reverse engineer closed-source binaries, reconstructing logic and identifying potential weaknesses. Compared to earlier models, it shows a dramatic improvement in exploit success rates and complexity handling. The model is capable of chaining multiple vulnerabilities together to bypass modern security defenses. It can assist both defenders and attackers, depending on how it is used, highlighting the dual-use nature of advanced AI systems. These capabilities have led to initiatives focused on strengthening cybersecurity defenses using the model. Overall, Claude Mythos Preview represents a major advancement in AI-driven security research and automation.

Description

Holo4 is H Company's series of generalist computer-use and agentic AI models built to perform multi-step work across software interfaces. It is available as Holo4 27B, a dense 27-billion-parameter model, and Holo4 35B-A3B, a Mixture-of-Experts model containing 35 billion total parameters with 3 billion active. Holo4 can interact with applications by clicking and typing through graphical interfaces, writing and executing code, or calling MCP and API tools. The same model can operate across desktops, websites, Android devices, code sandboxes, and business APIs without requiring developers to select a separate specialized model for each environment. H Company trained Holo4 using 127 billion supervised fine-tuning tokens, with approximately three-quarters consisting of successful agentic trajectories spanning desktop, web, MCP/API, and mobile tasks. Reinforcement learning then trained separate experts for desktop and web interaction and for terminal, MCP, and API work before merging them into a single model. Holo4 27B scored 85.2% on OSWorld, 61.7% on OSWorld 2.0, 45.4% on AutomationBench, and 85.1% on AndroidWorld in the evaluations reported by H Company. The models support a 256K context window, with the 27B model positioned for greater accuracy on long multi-step tasks and the 35B-A3B version positioned as a faster and less expensive alternative. Holo4 is available through a hosted API and downloadable model weights, enabling developers and enterprises to build agents that perform workflows spanning multiple applications and interaction methods.
