Claude Haiku 5.5 (Xhigh)

Claude Haiku 5.5 (Xhigh) records an intelligence index of 41.2 in Franklin's current Artificial Analysis-sourced snapshot. Within the five listed Haiku 5.5 settings, that places its aggregate result above High and below Max. This is a comparison of captured scores, without a claim that every task follows the same order. Xhigh gives you another configuration to include when High and Max produce different quality, latency, or cost results in your own evaluation. Use identical prompts and judge the outputs against the same requirements. Check performance and pricing independently of the intelligence index. Missing coding or math measurements cannot be filled in from the family name or inferred from the aggregate result.
