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
Hy4 preview is a new-generation open source Mixture-of-Experts flagship model built for real-world productivity tasks across software engineering, office work, game development, and scientific research. The model contains 770B total parameters with 49B activated per token and supports a 1M-token context window, giving it the capacity to work through large codebases, extensive document collections, and long multi-step tasks. Its 78-layer architecture combines Gated DeepSeek Sparse Attention with IndexCache for cross-layer sparse index reuse and identity Hyper-Connections to expand information flow between layers. A native Multi-Token Prediction layer is included for speculative decoding. Hy4 preview is designed to understand, plan, debug, and verify long-horizon engineering tasks, with additional gains in front-end visual quality and interaction design.
