Claude Haiku 5.5 (Max) vs Claude Opus 5.5 (Max, Default Fallback)

What the captured data shows

Haiku 5.5 Max improves the aggregate index available for the Haiku configuration while retaining lower listed token rates than Opus 5.5. Opus still has the higher intelligence index in the captured records. Both entries show substantial first-token delays, so a fast-looking throughput figure should not be mistaken for immediate delivery.

Which model fits your workflow

Use the same task and acceptance rule when testing these entries. Include the waiting period before the first token and the total time to an acceptable answer. If Haiku needs extra attempts, include those attempts in the practical cost comparison.

Decision takeaway

Haiku Max offers lower listed prices with a lower recorded aggregate index. Check whether that difference affects the result you need.
