Claude Haiku 4.5 is the small, fast member of the Claude family. It's a common pick for the many cheap calls an agent makes — file triage, summarization, tool routing, subagents — where Opus or Sonnet would be overkill. Quality is a clear step below the larger Claudes but the speed and price are the point.

Strengths
  • Very fast responses
  • Cheap enough for high-volume loops
  • Same Claude reliability and tool use
Trade-offs
  • Quality well below Sonnet/Opus on hard tasks
  • 200K context, not 1M
