When to consider this model

Consider it for difficult code review, reasoning across documents, architecture planning, and long-running agents. Use a real task with acceptance criteria to see whether it reduces rework before assigning it to an entire workflow.

How to evaluate it

Start with a tested code task and record first-pass acceptance, tool calls, input and output tokens, latency, and billing. Then add one image with a specific question and a long-context segment to evaluate visual and context handling separately.

What to check before integration

Use the exact claude-opus-5.5 ID. The published reference lists 15x (CNY 6 / 1M tokens), 1M context, and image support; live availability, output and cache billing must be confirmed from the live catalogue, ledger, and a real request.
