What is GPT-5.5-Cyber?

GPT-5.5-Cyber is an advanced AI model designed for authorized cybersecurity professionals who need stronger support for vulnerability research, codebase analysis, and remediation. The model builds on GPT-5.5’s general-purpose intelligence while adding more capable and permissive behavior for specialized defensive security workflows. It is designed to help reduce unnecessary refusals for verified defenders while still pairing advanced capabilities with verification, monitoring, scoped controls, and review. GPT-5.5-Cyber can sustain deeper analysis across large and complex codebases, making it useful for identifying security-relevant components and tracing how vulnerabilities may be reached. It can also help validate likely issues in controlled environments, develop and test patches, and organize evidence for human security teams. The model is intended to support the full remediation loop, helping defenders move from discovery to validation to fix preparation instead of only producing raw vulnerability findings. In benchmark testing, GPT-5.5-Cyber outperformed GPT-5.5 on CyberGym, ExploitGym, and SEC-bench Pro. These results show improved performance in reproducing known vulnerabilities, reasoning through exploitability, and handling long-horizon vulnerability discovery and proof-of-concept workflows. The model is also being evaluated through complex repositories and real remediation workflows as coordinated disclosures conclude. GPT-5.5-Cyber is positioned as a higher-capability option for defenders whose authorized work requires the most advanced cyber support, while GPT-5.5 with Trusted Access for Cyber and Codex Security remains the recommended starting point for most defenders. GPT-5.5-Cyber helps qualified security teams work faster, validate vulnerabilities more effectively, and support safer remediation across critical software systems.

What is Claude Mythos 5?

Claude Mythos 5 is Anthropic’s restricted-access Mythos-class AI model built for trusted organizations that require the highest level of Claude capability. The model shares the same underlying architecture as Claude Fable 5, but is offered with certain safeguards removed for approved use cases and vetted users. Claude Mythos 5 is designed for advanced cybersecurity, software engineering, scientific discovery, long-context reasoning, and autonomous research workflows. It is initially deployed through Project Glasswing for cyberdefenders and critical infrastructure providers. The model is intended to help security teams analyze complex systems, support defensive cybersecurity work, and protect important software environments. Claude Mythos 5 also demonstrates major potential in life sciences, where it can assist with protein design, binding-site selection, bioinformatics workflows, and research hypothesis generation. Anthropic reports that the model can carry out extended technical tasks, recover from failures, and operate with a high degree of autonomy. Its capabilities in genomics include assembling large-scale single-cell datasets and designing custom machine learning approaches for biological research. Because these capabilities may be dual-use, Anthropic limits access through trusted programs and applies a 30-day retention policy for Mythos-class traffic. The model is priced at $10 per million input tokens and $50 per million output tokens. Claude Mythos 5 helps vetted organizations apply frontier AI to critical defense, infrastructure, and scientific problems while maintaining controlled access and oversight.
