Claude Fable 5 (Adaptive Reasoning, Max Effort, Opus 5 Fallback)

Claude Fable 5 is an artificial intelligence model developed by Anthropic that features adaptive reasoning, max effort processing, and an Opus 5 fallback mechanism. The model is currently available with a pricing structure set at 10.00 dollars per million tokens for input and 50.00 dollars per million tokens for output, resulting in a blended rate of 20.00 dollars per million tokens. Specific performance metrics, including output speed and time to first token, remain unknown at this time. Furthermore, there are no standardized benchmark rows available for this model to provide a comparative analysis of its intelligence, coding, or mathematical capabilities. This model represents a specific configuration within the broader Anthropic product ecosystem.
