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

SWE-2 Flash is a high-speed AI software engineering model developed by Cognition for automated coding, development workflows, and technical problem-solving. The model is based on Inkling-Small from Thinking Machines and uses a mixture-of-experts architecture containing 276 billion total parameters and 12 billion active parameters. Cognition applies large-scale mid-training and reinforcement learning to improve the model's programming accuracy, reasoning capabilities, and ability to complete complex software engineering tasks. SWE-2 Flash supports code generation, repository maintenance, automated code reviews, feature implementation, documentation updates, and agent-driven software development. Its optimized architecture delivers approximately 200 tokens per second, making it three times faster than SWE-2 while operating at one-fifth the inference cost. The model achieved a score of 24.0% on FrontierCode 2.0, 45.5% on FrontierCode 1.1 Main, and 89.2% on Terminal-Bench 2.1 in Cognition's published evaluations. Training improvements also target general reasoning, problem-solving, and cybersecurity tasks to expand the range of activities supported by autonomous coding agents. SWE-2 Flash is available in Devin Desktop and CLI, allowing developers to incorporate the model into interactive and automated software engineering workflows. Cognition is also developing a controlled model-weight access program for trusted industry partners and researchers interested in fine-tuning, infrastructure control, and deployment in sensitive environments.
