▶️ Quick Scenario:

You’re building an AI help widget for a high-traffic ecommerce store. Each session needs:

• 120 words of context (≈ 160 tokens)
  
• 220 words of responses (≈ 295 tokens)

Meet Claude Haiku 4.5

Claude Haiku 4.5 is Anthropic’s fastest and most cost-efficient current model. Anthropic positions it as a near-frontier option for teams that want strong performance without paying Sonnet- or Opus-level rates, and says it is designed for real-time, high-volume use cases. Anthropic also states that Haiku 4.5 runs through the Claude API as claude-haiku-4-5 and highlights its strong balance of speed, capability, and cost efficiency.

Think of it as the model you choose when latency, scale, and unit economics matter just as much as quality.

Claude Haiku 4.5 vs. Claude Sonnet 4.6 — Speed vs. Balance

Hybrid tip: Run Haiku 4.5 for live chat, FAQ handling, classification, and agent sub-tasks, then escalate only the hardest reasoning, coding, or workflow-orchestration cases to Sonnet 4.6 or Opus 4.5. Anthropic’s own launch post describes Sonnet 4.5 planning work that can orchestrate multiple Haiku 4.5 agents in parallel.

When to Choose (or Skip) Claude Haiku 4.5
