Anthropic: Claude Opus 4.8
Analysis Summary
Claude Opus 4.8 is Anthropic's current flagship model, released May 2026. It holds the second-highest intelligence index in the database at 55.7, with a coding index of 56.7 and an agentic index of 76.4, placing it at or near the top of the field across all three primary capability dimensions. It supports text, image, and file input with tool use, function calling, and a 1M token context window.
For businesses, Opus 4.8 is the strongest available choice for autonomous coding agents, complex multi-step reasoning, long-document analysis, and high-stakes client-facing content. Its terminalbench score of 0.583 and scicode score of 0.535 confirm frontier-level performance on hard technical tasks. The main trade-off is cost: at $5 input and $25 output per million tokens, it is expensive for high-volume or routine workloads.
Adopt Opus 4.8 where answer quality, reasoning depth, and agentic reliability are the primary requirements. Pair it with a cheaper model such as Claude Sonnet for routine or high-volume calls to manage cost without sacrificing quality on tasks that demand it.
