About

Claude Fable 5.5 is not currently an announced or released Anthropic model as of September 30, 2026. Anthropic's current model documentation lists Claude Fable 5.1 as the latest Fable model alongside Claude Opus 5.5 and Claude Sonnet 5.5. Fable 5.1 remains Anthropic's premium model for demanding reasoning and long-horizon agentic workloads, with a 1-million-token context window and maximum output of 128,000 tokens. It uses adaptive thinking that is always enabled and defaults to a high reasoning effort level. Fable 5.1 is priced at $10 per million input tokens and $50 per million output tokens, with cache reads priced at $0.25 per million tokens. Anthropic has released Opus 5.5 and Sonnet 5.5, but there is currently no official model documentation, pricing, release date, benchmark data, or API identifier for Claude Fable 5.5.

About

Stableoutput is a user-friendly AI chat client that allows users to interact with popular AI models like OpenAI's GPT-4o and Anthropic's Claude 3.5 Sonnet without requiring coding knowledge. It operates on a bring-your-own-key model, meaning users utilize their own API keys, which are securely stored in the browser's local storage; these keys are not transmitted to Stableoutput's servers, ensuring privacy and security. The platform offers features such as cloud synchronization, a usage tracker to monitor API consumption, customization options for system prompts, and model settings like temperature and maximum tokens. Users can upload PDFs, images, and code files for AI analysis, facilitating more personalized and context-aware interactions. Additional functionalities include pinning and sharing chats with controlled visibility and managing message requests to optimize API usage. Stableoutput provides lifetime access with a one-time payment.
