Anthropic: Claude Opus 4.5 (batch)

Claude Opus 4.5 from Anthropic is designed for handling text, images, and files with a vast context length of up to 200,000 tokens and robust support for tools and reasoning. This model excels in processing complex tasks and can generate structured outputs when needed. While it scores well on benchmarks like AI Index and EqBench (76.8), the blended score is modest at 72.6 across only two benchmarks, indicating a mix of strengths and areas for improvement. For users seeking a flexible model that supports multiple input types and advanced reasoning, Claude Opus 4.5 could be worth considering, especially if cost is not a major constraint due to its pricing at $2.5 per million input tokens and $12.5 per million output tokens. However, given the limited benchmark coverage, potential users should weigh these costs against the model’s performance comprehensively before shortlisting it for critical applications.
