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-5.6-Cyber is a cybersecurity-focused OpenAI model introduced for trusted defenders through Daybreak Red access. Built on GPT-5.6 Sol, the model is trained to improve performance on advanced security research, vulnerability discovery, exploit validation, and specialized defensive workflows. GPT-5.6-Cyber is intended for authorized users who need deeper support across vulnerability research, security testing, exploit-chain analysis, incident response, malware analysis, secure code review, patch validation, and technical documentation. OpenAI created Daybreak to give approved individuals and organizations access to frontier cyber capabilities while managing the risks of reduced safeguards. Daybreak Blue provides access to frontier general-purpose models with safeguards tailored for defensive security work, while Daybreak Red provides access to cybersecurity-specific models such as GPT-5.6-Cyber. The model is designed to reduce unnecessary refusals that can interrupt legitimate security research while still operating inside a trusted access program. OpenAI reports that GPT-5.6-Cyber improves performance on certain specialized cybersecurity evaluations and has been used to support real-world vulnerability research and coordinated disclosure. Access controls include identity verification, account security, monitoring, legal attestations, approved-use restrictions, and additional requirements such as hardware security keys for individual Daybreak accounts. By combining cyber-specific training, trusted access controls, reduced refusal behavior, vulnerability research capabilities, and safety practices, GPT-5.6-Cyber helps approved defenders conduct advanced security work more effectively.
