Give a Claude Opus 5 vs Sonnet 5… enough context to make the result specific, then test the part that matters to your project.
- 01
Segment tasks by consequence
Create groups for simple explanation, bounded edit, Blueprint plan, log diagnosis, architecture decision, long-running feature, visual review, and release-sensitive change. Record the correct answer and review cost.
- 02
Run a matched matrix
Give both models identical source, assets, logs, tools, permissions, effort ceiling, time budget, Unreal version, target, and acceptance checks. Repeat enough times to observe variance rather than scoring one lucky run.
- 03
Measure reviewer burden
Count unsupported assumptions, overbroad edits, missed project conventions, unnecessary tool calls, explanations reviewers must reconstruct, and failures detected only by native compilation or runtime tests.
Why use it
Make the next decision with something real.
Focus on the parts of the idea that need a concrete result before the next decision.

FAQ
Questions about Claude Opus 5 vs Sonnet 5…
Is Opus 5 always better than Sonnet 5?
No. Anthropic positions the tiers differently, and task-specific quality, speed, price, tools, and reviewer effort determine the best route.
Which should handle difficult Unreal bugs?
Start by testing Opus 5 on the hardest ambiguous cases, but require preserved failure evidence and native verification.
Which should handle routine code changes?
Use the model that produces the most accepted changes per unit of total cost, including review and retries; Sonnet may be the better hypothesis for volume.
