Anthropic: Claude Fable 5
The Anthropic: Claude Fable 5 is an AI model that handles text, image, and file input modalities within a context length of one million tokens. It supports reasoning capabilities and comes equipped with various tools, but its structured output options are undefined. The model can process complex inputs due to its high max completion token count. This model's pricing stands out at $10 per million input tokens and $50 per million output tokens. While it has a solid benchmark performance of 95.6 across two independent benchmarks, its coverage is limited to only two metrics, making broader evaluation uncertain. The Anthropic: Claude Fable 5 may be worth shortlisting for users seeking an AI model with reasoning capabilities and multi-modal input support who are willing to invest in its high output costs despite some uncertainty surrounding its overall performance.
