Operator guidance
The price/performance sweet spot of the Claude 4 line — a sensible default. Step up to Opus 4 for the hardest tasks; drop to Haiku 4 for cost/latency.
Use cases
- The default workhorse: strong quality at a moderate price/latency
- Production coding agents, RAG, and tool use at scale
Limitations
- Not as strong as Opus 4 on the very hardest reasoning/agentic tasks
- Capability ratings are qualitative, not a single cited benchmark run
