Description
Claude Fable 5.5 is an anticipated but currently unannounced model in Anthropic's Claude family, and Anthropic has not confirmed that a model with this name will be released. As of September 30, 2026, Claude Fable 5.1 remains the latest officially documented Fable model. Fable represents Anthropic's highest-end model tier for demanding reasoning and long-horizon agentic work, while the newer Opus 5.5 and Sonnet 5.5 occupy lower-cost positions in the Claude lineup. Anthropic's current documentation gives Fable 5.1 a 1-million-token context window and maximum output length of 128,000 tokens. It supports text and image inputs with text output and uses adaptive thinking that remains active throughout model operation. Fable 5.1 defaults to high reasoning effort and is listed as having a June 2026 reliable knowledge cutoff and training-data cutoff. API pricing is $10 per million input tokens and $50 per million output tokens, while prompt-cache reads cost $0.25 per million tokens and Batch API processing receives a 50% input and output discount. Anthropic's official documentation currently provides model identifiers for Fable 5.1 across the Claude API, Amazon Bedrock, Google Cloud, Microsoft Foundry, and Claude Platform on AWS. No equivalent model identifier, specifications, benchmark results, pricing, availability information, or release schedule has been published for Claude Fable 5.5.
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.
