Anthropic: Claude Opus 4.8
Claude Opus 4.8 is a paid model from Anthropic that accepts text, images, and file uploads, giving it a broad intake for mixed-media workflows. Its context window reaches one million tokens, and it supports tool use and reasoning, making it a viable candidate for multi-step agentic tasks. Maximum output sits at 128,000 tokens per response. Structured output support is not confirmed in available specifications. At $5.00 per million input tokens and $25.00 per million output tokens, this is a premium-tier model, so cost-conscious teams running high-volume inference should weigh that carefully. Its blended benchmark score of 95.5 across four benchmarks is strong, and a perfect score on the coding sub-benchmark stands out for developer-focused use cases; the agentic score of 77.8 is more moderate, worth noting if autonomous task completion is the primary requirement. Teams doing document-heavy analysis or complex coding work have the clearest case for shortlisting it.
