Claude Haiku 4.5
Very low latency for high-volume, simple tasks — classification, short summaries, and lightweight chat where response time matters more than depth.
Noticeably weaker on multi-step reasoning and long-context synthesis; pairing with a larger model for escalation is common.
Claude Opus 4.8
Best-in-class for complex multi-step agentic workflows, long-horizon planning, and large codebase refactors. Strong instruction-following on ambiguous, open-ended tasks.
Highest per-token cost in the catalog and noticeably higher latency — reserve for tasks that genuinely need top-tier reasoning rather than routine completions.
