Description
Claude Fable 5.2 is a frontier artificial intelligence model developed by Anthropic for advanced reasoning, autonomous software development, scientific discovery, and complex professional workflows. The model improves on Claude Fable 5.1 with stronger performance in programming, visual analysis, mathematical problem-solving, and agent-driven task execution. Its software engineering capabilities support large-scale codebase analysis, feature implementation, debugging, performance optimization, automated testing, and complex software migrations. Claude Fable 5.2 can coordinate multiple AI agents to complete long-running engineering projects and delegate simpler operations to smaller language models. The model also supports scientific research, hardware design, robotics-related reasoning, data analysis, and technical investigations that require iterative experimentation and evaluation. Configurable reasoning effort allows developers to balance computational cost, response time, and problem-solving depth according to task requirements. Anthropic reports a 49.1% score on FrontierCode 2.0, 69.9% on FrontierSWE v2, and 74.2% on Humanity's Last Exam with tools. Claude Fable 5.2 generates output up to 30% faster than its predecessor and offers an optional fast mode with up to 2.5 times faster generation, alongside safeguards for high-risk cybersecurity and biological research. The model is available through Claude applications, Claude Code, Anthropic's API, Amazon Web Services, Google Cloud, and Microsoft Azure, with standard API pricing of $8 per million input tokens and $40 per million output tokens.
Description
GPT-6 Cyber is a specialized artificial intelligence model developed by OpenAI for advanced cybersecurity research, vulnerability discovery, and authorized offensive security testing. The model combines frontier reasoning capabilities with cybersecurity-specific training to identify software weaknesses, investigate attack paths, and validate exploitable vulnerabilities. Its autonomous research capabilities allow security professionals to analyze complex codebases, reproduce known vulnerabilities, discover previously unknown flaws, and develop working proof-of-concept exploits. GPT-6 Cyber also assists with secure code reviews, vulnerability triage, patch generation, and verification of security fixes. During OpenAI's security research, the model helped identify 81 previously unknown high-severity vulnerabilities in Firefox and develop working exploits for 948 Linux kernel vulnerabilities. Its ExploitGym benchmark score of 48.5% represents a substantial improvement over GPT-5.6 Cyber's 32.1% result. Specialized alignment training helps the model follow rules of engagement, respect authorized testing boundaries, and avoid accessing unrelated systems during security investigations. Additional safeguards include cyber-specific activity monitoring, sandboxing recommendations, access restrictions, and controls designed to prevent harmful use against critical infrastructure. GPT-6 Cyber is available to selected approved customers through OpenAI Daybreak Red, with API and Codex access supporting advanced defensive research, vulnerability validation, and security testing workflows.
