When to choose Claude Opus 5.5
1
Architecture decision
Turn requirements and constraints into options, trade-offs, and a decision record.
Prompt starter
Act as a staff architect. Compare three approaches for [system]. Use these constraints: [constraints]. Return a decision table, risks, migration steps, and a final recommendation.
2
Repository-scale code review
Trace behavior across files, identify failure paths, and propose a scoped patch plan.
Prompt starter
Review the attached code for [goal]. Trace the request end to end, list findings by severity with file evidence, then propose the smallest safe patch and focused tests.
3
Multi-step agent plan
Decompose a long-running goal into checkpoints, tools, verification, and recovery steps.
Prompt starter
Plan and execute [goal] in checkpoints. Before each action state the evidence needed; after each action verify the result and update the remaining plan. Stop on irreversible ambiguity.

What inputs does Claude Opus 5.5 currently support in PixMind?
This PixMind route accepts text and images. Video, audio, or PDF availability is shown separately and should not be inferred from the model family. The current catalog flags: text, vision.
How should I prompt Claude Opus 5.5?
State the outcome and constraints directly. For long work, define checkpoints and the expected deliverable instead of repeatedly asking the model to be thorough.
How is Claude Opus 5.5 usage priced?
Studio and API share the same rates: $3.20 per 1M input tokens and $16 per 1M output tokens, at 80% of the official reference. Cache reads and 5-minute or 1-hour cache writes have separate rates below.
When should I choose another model over Claude Opus 5.5?
Claude Opus 5.5 is positioned for architecture decisions, repository review, and multi-step technical reasoning. Check the comparison table when lower cost, different input support, or a heavier reasoning tier matters more.
What should I do if a Claude Opus 5.5 response stops?
A network interruption, insufficient balance, or temporary model availability can stop a reply. Before resending, check whether token usage and points were already settled.
