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
An EU-based company offers an inference API compatible with OpenAI and Anthropic models. Their premier model operates on dedicated GPUs located in EIA data centres and ensures that no data is retained, as all prompts and completions are processed solely in memory—meaning they are neither stored nor logged, and are not utilized for training purposes. Additionally, users have access to routed open models from various third-party providers using the same key, which are also clearly marked. The service includes a Data Processing Agreement (DPA) and an invoice from the EU entity. Notable features include streaming capabilities, tool calling, structured output, a publicly available DPA and sub-processor list, as well as a pricing model based on token usage. During a measurement conducted on the live system in August 2026, the service demonstrated a capacity of processing 176 tokens per second per stream, with the first token being generated in just 0.3 seconds, highlighting its efficiency and speed. Such performance metrics are critical for developers seeking reliable and rapid AI solutions in their applications.
