Verdict

Missing from this catalog until now, which undersold it — this is Anthropic's first Haiku with extended thinking and computer use, matching Claude 4 Sonnet on reasoning and coding at $1/$5 per million tokens. 73.3% on SWE-bench Verified is a real number for a "fast" model. Drop-in replacement for Haiku 3.5 or Sonnet 4 wherever you were paying more than you needed to.
