It’s the cheapest and fastest Claude model yet, costing nearly 75% less than Haiku 4.5.
It beats GPT-6 Luna and approaches Sonnet 5.5-level performance in benchmarks.
Anthropic might have once wondered whether it should slow down AI development, but the company has since only become more aggressive.
It released the new Opus 5.5 model last month, followed by the slightly more economical Sonnet 5.5 nearly a week ago.
Now, it’s back with an even faster and more affordable model.
Anthropic today announced the new Claude Haiku 5.5 model, positioning it as the model of choice for high-volume, cost-sensitive tasks.
Haiku 5.5 outperforms its predecessor, Haiku 4.5, by a noticeable margin.
It approaches the benchmark numbers achieved by the considerably more expensive Sonnet 5.5 and beats the recently released GPT-6 Luna across all benchmarks shared by Anthropic.
