Anthropic's Claude Haiku 5.5 cuts prices but adds a 100K token cliff

By PulseAugur Editorial · [11 sources] ·

Anthropic has released Claude Haiku 5.5, a new iteration of its cost-effective language model. While the base price for prompts under 100,000 tokens has significantly decreased, potentially by up to 90% compared to Haiku 4.5, a new pricing tier and tokenizer mean that prompts exceeding this threshold incur a fivefold increase in cost. This change, coupled with a new tokenizer that counts text as approximately 30% more tokens, necessitates careful prompt engineering and monitoring to manage expenses effectively. The model also introduces adjustable "effort" settings, impacting thinking time and cost, and shows improved performance on benchmarks like Terminal-Bench, making it a more capable option for certain agentic tasks. AI

IMPACT New pricing structure and improved performance for Haiku 5.5 may shift adoption patterns for cost-sensitive, high-volume AI tasks.

RANK_REASON Model release from a frontier lab (Anthropic) with specific pricing and performance details.
