Where it may fit
These are evidence-bounded screening suggestions, not performance claims or purchase recommendations.
Code and reasoning evaluation
Consider it for hosted evaluations that span code generation, code autocompletion, and mathematical or quantitative reasoning.
Evidence fields: tasks, access [1]
Document and vision workflows
Consider it when OCR, image captioning, and visual question answering appear in the same workflow as language generation.

Limitations
The record documents task scope only. It does not report benchmark results, price, context window, latency, or safety evaluations, and no exact-match Arena rating exists for this record in the pinned snapshot.
Current standing
According to the LMArena snapshot published July 16, 2026, no exact match for this catalog record appears in the style-controlled text category, so this page reports no current rating for Claude Opus 4.5.
