High-volume summaries, classification, and subagent coding need a model you can afford to call repeatedly. Anthropic launches Claude Haiku 5.5 at a stated 75% lower average cost, with adjustable effort to trade cost against capability.

Here's what changed:
- Prompts up to 100,000 tokens cost 90% less, at $0.10 per million input tokens and $0.50 per million output tokens.
- Prompts above 100,000 tokens cost 50% less, at $0.50 for input and $2.50 for output per million tokens.
- Anthropic reports 39.2% on Terminal-Bench 4.0, versus Haiku 4.5's 0.0% and GPT-6 Luna's 16.4%.
- Adjustable effort is new to the Haiku class, letting you choose the cost-capability tradeoff.

One catch: The changed tokenizer consumes slightly more tokens per task.
