Claude Sonnet 4.5 from Anthropic is designed for extensive text, image, and file processing with a context length of 1 million tokens. It supports reasoning and tools integration, enabling more complex tasks, though structured output support remains unimplemented.

Its blended benchmark score of 64.8 across four metrics suggests strong performance, albeit with some areas needing improvement. With a pricing structure of $1.5 per million input tokens and $7.5 per million output tokens, it offers flexibility but comes at a cost that may not be ideal for all budgets, particularly considering its current ranking in the benchmark coverage category.
