Anthropic releases Claude Haiku 5.5

Why it matters to executives

1. Anthropic's cheapest, fastest small model, aimed at high-volume work (summaries, classification, queries).
2. AWS says it costs roughly 75% less than Haiku 4.5 on Bedrock.
3. Re-price any high-volume AI workflow: unit costs for routine tasks keep falling.
