About
Claude Mythos 5.2 is an advanced AI reasoning model developed by Anthropic for cybersecurity research, biomedical science, autonomous software engineering, and complex technical problem-solving. The model shares its underlying architecture with Claude Fable 5.2 but provides verified organizations with access to specialized cybersecurity and biological research capabilities that are restricted in the general-purpose version. Its capabilities include vulnerability discovery, secure code analysis, scientific research, protein design, technical investigations, and autonomous agent workflows. Claude Mythos 5.2 demonstrates improved vulnerability identification and scientific reasoning, achieving 76.3% on CyScenarioBench and 89.6% on Anthropic's CVE Rediscovery evaluation. The model generates output up to 30% faster than its predecessor and offers an optional fast mode that increases token generation speed by up to 2.5 times.

About
SWE-2 is Cognition’s advanced coding model designed to improve software engineering performance while reducing the cost of agentic coding workflows. The model is post-trained from Kimi K3 and uses reinforcement learning to optimize multiple reasoning-effort levels within a single training run. SWE-2 is designed to explore codebases more selectively, begin implementation sooner, and complete tasks with fewer redundant reads and reasoning steps than earlier Cognition models. Its capabilities include code generation, debugging, test creation, verification, repository analysis, and complex terminal-based software engineering tasks. The model also emphasizes stronger engineering judgment, end-to-end test coverage, instruction following, and evidence-based verification of user assumptions. SWE-2 is available through Devin Desktop and Devin CLI, with broader rollout planned across Devin Web and Fusion.
