Anthropic: Claude Opus 4.5

Claude Opus 4.5 is Anthropic's paid model accepting text, images, and file uploads, with a 200,000-token context window and up to 64,000 tokens of output per response. It supports tool use and reasoning, making it suitable for multi-step tasks and agentic workflows. Structured output support is unconfirmed based on available data. At $5.00 per million input tokens and $25.00 per million output tokens, this is an expensive option, particularly on the output side. Its blended benchmark score of 78.5 covers only two benchmarks, so that figure should be treated as suggestive rather than definitive. Teams that need large-context processing, tool-integrated pipelines, or reasoning over uploaded documents may find it worth shortlisting, but cost-sensitive users should weigh output volume carefully before committing.
