For coding Haiku 5.5 matches Sonnet at a tenth of the price
Anthropic released Claude Haiku 5.5 overnight, and the pace has not eased. Last year’s small model, Haiku 4.5, cost US$1 in and US$5 out per million tokens. Haiku 5.5 is US$0.10 and US$0.50, a tenth of the price, and Anthropic calls it its cheapest, fastest and most capable small model yet.
That is the pattern across the whole industry this year. Often each release is cheaper and quicker than the last, and every lab is pushing the others. OpenAI’s GPT-6 Luna sits at exactly the same price and appears in Anthropic’s own comparison table. Competition is working, and we are the ones collecting the winnings.
