Anthropic has lowered pricing for its Claude Haiku 5.5 model by approximately 75% against its predecessor, while actions to block rival labs from distilling its models have reduced a dedicated revenue stream.[^1]

Distillation revenue previously made up 5% to 7% of Anthropic's total revenue. The company states its anti-distillation protocols have reduced harvesting of model data by 90 to 99%.[^2][^3] This enforcement is identified as a likely contributor to slowed third quarter revenue growth.[^4]

Anthropic has advised investors distillation revenue will decline further in future periods. The price cut comes amid an ongoing price war with OpenAI and Chinese AI labs.[^5] The lab had previously disclosed to prospective investors that rival firms were training competing systems on Claude outputs.[^6]
